==Overview==
'''Health Sciences''' is the multidisciplinary field of applied science that deals with [[Health|health]], [[Disease|disease]], and healthcare. It combines traditional scientific disciplines (such as biology and chemistry) with clinical practices to improve the well-being of humans and animals.

In the context of '''[[Stomatology]]''', the health sciences provide the physiological and biochemical foundation upon which all dental treatments are built.

==Core Disciplines in Health Sciences==

===1. Biomedical Sciences===
The biological foundation of clinical practice.
* '''[[Anatomy]]''': The study of the structure of the human body, specifically the [[Maxillofacial]] complex.
* '''[[Physiology]]''': How the body functions, including salivary flow and bone remodeling.
* '''[[Histology]]''': The microscopic study of tissues, essential for [[Oral and Maxillofacial Pathology]].
* '''[[Pharmacology]]''': The study of drugs, including [[Local Anesthesia]] and antibiotics.

===2. Clinical Sciences===
The application of theory to patient care.
* '''[[Dentistry]]''': The primary focus of this wiki, specializing in oral health.
* '''[[Medicine]]''': The broader field encompassing systemic health.
* '''[[Nursing]]''' and '''[[Dental Hygiene]]''': The essential support and preventive branches of clinical care.

===3. Population Health===
The study of health at a societal level.
* '''[[Epidemiology]]''': Tracking the spread of oral diseases (e.g., the prevalence of [[Dental Caries]]).
* '''[[Dental Public Health]]''': Policies aimed at community-wide prevention.
* '''[[Bioethics]]''': The moral framework governing patient autonomy and professional conduct.

==The Interdisciplinary Nature of Health Sciences==
Modern healthcare in 2026 emphasizes the '''Interprofessional Education (IPE)''' model. This means that a student of the health sciences must understand how different fields overlap:
* **Nutrition Science**: Impacts tooth development and decay.
* **Biomaterials Science**: The engineering of [[Zirconia]], [[Titanium]], and composite resins.
* **Genetics**: Understanding hereditary conditions like [[Amelogenesis Imperfecta]].

==Overview==
The intersection of '''Dentistry''' and '''Medicine''' is increasingly recognized through the "Oral-Systemic Link." While dentists are doctors of the oral cavity, their work frequently overlaps with various medical specialties. This category serves as a directory for those medical fields that collaborate most closely with dental professionals.

==Primary Intersections==

===1. Oncology & Hematology===
* '''[[Oral Cancer]]''': Requires collaboration between [[Oral and Maxillofacial Surgery|Oral Surgeons]], Medical Oncologists, and Radiation Oncologists.
* '''[[Hematology]]''': Crucial for managing patients with bleeding disorders (e.g., Hemophilia) or those on anticoagulant therapy before surgical procedures.

===2. Cardiology===
* '''[[Infective Endocarditis]]''': A critical area where dental infections or procedures can impact heart valve health.
* '''[[Cardiovascular Disease]]''': Studied extensively in [[Periodontology]] due to the inflammatory links between gum disease and heart health.

===3. Endocrinology===
* '''[[Diabetes Mellitus]]''': Perhaps the most significant medical-dental intersection. Poor glycemic control exacerbates [[Periodontitis]], while chronic oral inflammation can interfere with blood glucose regulation.

===4. Otolaryngology (ENT)===
* '''[[Maxillary Sinusitis]]''': Often odontogenic (tooth-related) in origin.
* '''[[Sleep Apnea]]''': Managed collaboratively using Mandibular Advancement Splints (MAS) or orthognathic surgery.

===5. Anesthesiology===
* '''[[Sedation Dentistry]]''': The use of pharmacological agents to manage patient anxiety and pain, ranging from [[Nitrous Oxide]] to General Anesthesia.

===6. Dermatology===
* Many systemic diseases first manifest as lesions on the '''[[Oral Mucosa]]'''. Conditions like Lichen Planus or Pemphigus Vulgaris require a dual diagnostic approach between [[Oral and Maxillofacial Pathology|Oral Pathologists]] and Dermatologists.

| focus = Remote dental care, triage, and consultation via telecommunications technology.
| related_fields = [[Digital Dentistry]], [[Dental Public Health]], [[Mobile Health]] (mHealth)
}}

==Definition==
'''Tele-dentistry''' is a subset of telehealth that uses electronic information and telecommunications technologies to support long-distance clinical oral health care, patient and professional health-related education, and public health administration.

It is not a separate specialty but rather a '''method of delivery''' for existing dental services, ranging from diagnostic triage to post-operative follow-ups.

==Modalities of Delivery==
Teledentistry is categorized into four distinct functional modalities:

===1. Synchronous (Live Video)===
Live, two-way interaction between a person (patient, caregiver, or student) and a provider using audiovisual telecommunications technology. This is commonly used for:
* Emergency '''[[Triage]]''' to determine if an in-person visit is necessary.
* Virtual consultations for '''[[Orthodontics]]''' or '''[[Cosmetic Dentistry]]'''.

===2. Asynchronous (Store-and-Forward)===
Transmission of recorded health information (e.g., intraoral photographs, [[Digital Radiology|radiographs]], and digital impressions) through a secure communications system to a practitioner who evaluates the data at a later time.
* This is highly effective in '''[[Dental Public Health]]''' programs where a hygienist in a school takes records for a dentist in a central office to review.

===3. Remote Patient Monitoring (RPM)===
Personal health and medical data collection from an individual in one location, which is transmitted to a provider in a different location for monitoring and care management.
* Examples include "Smart" toothbrushes that track brushing frequency and pressure, or remote monitoring of orthodontic aligner progress.

===4. Mobile Health (mHealth)===
Health care and public health practice and education supported by mobile communication devices such as cell phones, tablets, and PDAs.

==Applications in Clinical Practice==
* '''Emergency Management''': Assessing swelling or trauma remotely to prescribe antibiotics or analgesics before an in-person appointment.
* '''Post-Operative Follow-up''': Inspecting a surgical site (e.g., after an [[Oral Surgery|extraction]]) via high-resolution photos to ensure proper healing and rule out [[Alveolar Osteitis]].
* '''Oral Hygiene Instruction (OHI)''': Providing personalized coaching on brushing and flossing techniques without taking up physical chair time.

==Legal and Ethical Considerations==
The implementation of teledentistry requires strict adherence to regulatory standards:
* '''[[HIPAA]] Compliance''': In the U.S., platforms must be secure and encrypted to protect patient privacy (PHI).
* '''Licensure''': Practitioners must typically be licensed in the state or jurisdiction where the ''patient'' is located at the time of the encounter.
* '''Informed Consent''': Patients must be made aware of the limitations of a remote exam compared to a physical clinical exam.

==Benefits and Limitations==
{| class="wikitable"
! Benefits !! Limitations
|-
| Increased access for rural/underserved areas || Lack of tactile sensation (palpation)
|-
| Reduced overhead for follow-up care || Dependence on high-speed internet

}}

==Overview==
'''Dental instruments''' are specialized tools used by dental professionals to examine, manipulate, treat, and restore the oral cavity and its associated structures. Modern instruments are engineered for high precision, durability under '''[[Autoclave]]''' sterilization, and ergonomic comfort to prevent repetitive strain injuries.

==Classification by Function==
Instruments are generally categorized based on the specific clinical task they perform:

===1. Diagnostic Instruments===
The "Basic Three" found in almost every dental tray setup:
* '''[[Mouth Mirror]]''': Used for indirect vision, retraction of soft tissues (cheeks/tongue), and transillumination.
* '''[[Dental Explorer]]''' (e.g., Shepherd's Hook): Used to detect [[dental caries]], calculus, and irregularities in tooth structure.
* '''[[Periodontal Probe]]''': A graduated instrument used to measure the depth of the [[periodontal pocket]] in millimeters.

===2. Hand Cutting Instruments===
Used to manually remove tooth structure or refine cavity preparations:
* '''[[Spoon Excavator]]''': Used to remove soft, carious dentin.
* '''[[Chisel]]''', '''[[Hatchet]]''', and '''[[Hoe]]''': Used to refine walls and floors of a cavity preparation.
* '''Gingival Margin Trimmer''': A specialized chisel for beveling the gingival cavosurface margin.

===3. Restorative Instruments===
Used for placing, carving, and contouring filling materials like [[Composite resin]] or [[Amalgam]]:
* '''[[Amalgam Carrier]]''': Transports material to the cavity.
* '''[[Condenser]]''' (Plugger): Compresses restorative material into the preparation.
* '''[[Burnisher]]''': Smoothes the surface of a restoration (e.g., Football or Ball burnisher).
* '''[[Carver]]''' (e.g., Hollenback or Discoid-Cleoid): Shapes the anatomy of the restoration before it hardens.

===4. Rotary Instruments===
High-speed and low-speed devices used for cutting and polishing:
* '''[[Dental Handpiece]]''': The air-driven or electric motor that holds the bur.
* '''[[Dental Bur]]''': The cutting head, made of tungsten carbide or diamond, available in various shapes (Round, Fissure, Inverted Cone).

===5. Surgical Instruments===
Specifically designed for [[Oral Surgery]] and [[Periodontology]]:
* '''[[Elevator]]''': Used to luxate (loosen) a tooth within its socket.
* '''[[Forceps]]''': Used to grasp and remove a tooth after it has been luxated.
* '''[[Periosteal Elevator]]''': Used to reflect a soft tissue flap from the bone.
* '''[[Hemostat]]''' and '''[[Needle Holder]]''': Used for grasping tissue and [[Suturing]].

==Materials and Maintenance==
* '''[[Stainless Steel]]''': The most common material due to its resistance to corrosion.
* '''[[Titanium]]''': Often used for instruments used around '''[[Dental Implants]]''' to prevent "galvanic shock" or scratching of the implant surface.
* '''Sterilization''': Instruments must undergo a rigorous cycle of ultrasonic cleaning followed by pressurized steam sterilization in an '''[[Autoclave]]'''.

==Ergonomics==
Modern instruments feature hollow, large-diameter handles with knurled (textured) surfaces to reduce "pinch force" and hand fatigue, decreasing the risk of '''[[Carpal Tunnel Syndrome]]'''.

| related_fields = [[Periodontology]], [[Implantology]], [[Anesthesiology]]
}}

==Definition==
'''Oral Surgery''' refers to any medical procedure performed in the [[oral cavity]] or on the jaws to treat a variety of conditions, defects, or injuries. While it is a recognized specialty (see [[Oral and Maxillofacial Surgery]]), many "minor" oral surgeries are performed by general practitioners in a clinical setting.

The primary goal of oral surgery is to restore function, alleviate pain, or resolve pathological conditions that cannot be managed through non-surgical means.

==Common Procedures==

===1. Dentoalveolar Surgery===
The most frequent category of oral surgery, involving the teeth and their supporting bone.
* '''[[Tooth Extraction]]''': The removal of a tooth from its socket in the [[alveolar process]].
* '''Surgical Extraction''': Required when a tooth is not easily accessible (e.g., broken at the gum line) and requires a soft tissue flap and bone removal.
* '''[[Impacted teeth]]''': Most commonly involving the third molars (wisdom teeth) that fail to erupt properly.

[Image of an impacted wisdom tooth classification]

===2. Preprosthetic Surgery===
Surgical preparation of the mouth before the placement of [[dentures]] or other prostheses.
* '''[[Alveoloplasty]]''': Reshaping and smoothing the jawbone after extractions.
* '''[[Torus Palatinus|Tori Removal]]''': The surgical reduction of bony outgrowths (tori) that interfere with denture fit.
* '''Frenectomy''': The removal of a "frenum" (fold of tissue) that may be causing a gap between teeth or interfering with tongue movement.

===3. Biopsy and Pathology Management===
When an abnormal lesion is found during a [[Stomatology|stomatological]] exam, oral surgery is required to obtain a definitive diagnosis.
* '''[[Incisional Biopsy]]''': Removing a small piece of a large lesion.
* '''[[Excisional Biopsy]]''': Removing the entire lesion (often used for small growths like fibromas).

===4. Periradicular Surgery===
Surgical procedures related to the root of the tooth, often performed when [[Endodontic Therapy]] fails.
* '''[[Apicoectomy]]''': The removal of the root tip and the surrounding infected tissue.

==Surgical Principles==
Success in oral surgery relies on several fundamental principles:
* '''[[Asepsis]]''': Maintaining a sterile or highly clean environment to prevent post-operative infection.
* '''Hemostasis''': Controlling bleeding during and after the procedure through pressure, suturing, or hemostatic agents.
* '''Flap Design''': Creating surgical incisions that preserve the blood supply to the soft tissue and allow for proper healing.
* '''[[Suturing]]''': The use of stitches (resorbable or non-resorbable) to close wounds and promote primary intention healing.

==Anesthesia and Sedation==
Oral surgery requires effective pain management. Depending on the complexity and patient anxiety, options include:
* '''[[Local Anesthesia]]''': Numbing a specific area (e.g., IANB for the [[mandible]]).
* '''[[Nitrous Oxide]]''': "Laughing gas" for mild sedation.
* '''[[Intravenous Sedation]]''': Inducing a state of deep relaxation while the patient remains conscious.

==Post-Operative Complications==
* '''[[Alveolar Osteitis]] (Dry Socket)''': Loss of the blood clot in an extraction site, leading to exposed bone and severe pain.
* '''Paresthesia''': Numbness or tingling caused by nerve trauma (often the [[Inferior Alveolar Nerve]]).
* '''Trismus''': "Lockjaw" or limited opening of the mouth due to muscle inflammation.

| image =
| caption = Progression from an infected pulp to a completed root canal obturation.
| specialty = [[Endodontics]]
| indications = Irreversible [[pulpitis]], apical [[periodontitis]], dental trauma.
| outcome = Retention of the natural tooth.
}}

==Definition==
'''Endodontic therapy''' is a sequence of dental treatments for the infected [[pulp]] of a tooth which results in the elimination of infection and the protection of the decontaminated tooth from future microbial invasion.

While popularly referred to as a "root canal," the root canal is actually the anatomical space within the root of a tooth; the therapy is the cleaning, shaping, and filling of that space.

==Indications for Treatment==
Endodontic intervention is required when the dental pulp becomes inflamed or infected. Common causes include:
* '''Deep [[Dental Caries]]''': Bacteria reaching the pulp chamber.
* '''Dental Trauma''': Impact causing pulp necrosis or internal resorption.
* '''Fractured Teeth''': Cracks extending into the pulp.
* '''Irreversible Pulpitis''': Severe inflammation where the pulp cannot heal, characterized by lingering pain to cold/heat and spontaneous pain.

==The Procedure (Step-by-Step)==

===1. Access Preparation===
The dentist or [[Endodontics|Endodontist]] creates an opening through the crown of the tooth (occlusal for molars, lingual for incisors) to reach the pulp chamber.

===2. Cleaning and Shaping===
The diseased pulp tissue is removed using specialized '''endodontic files'''.
* '''Irrigation''': The canals are flushed with disinfecting solutions, most commonly '''Sodium Hypochlorite''' (NaOCl), to dissolve organic debris and kill bacteria.
* '''Instrumentation''': Files are used to shape the canals into a tapered form to allow for effective filling.

===3. Obturation===
Once the canals are cleaned and dried, they are filled with a biocompatible material to prevent re-infection.
* '''[[Gutta-percha]]''': A thermoplastic latex material that is the standard for root canal filling.
* '''Sealer''': A medicinal cement used to ensure a fluid-tight seal between the gutta-percha and the canal walls.

===4. Restoration===
Because an endodontically treated tooth is "non-vital" (brittle) and often has significant lost structure, a final restoration is required.
* In most posterior teeth, a '''[[Dental Crown]]''' is mandatory to prevent tooth fracture.

==Success Rates and Prognosis==
Modern endodontic therapy has a success rate of approximately 85% to 97%. Factors affecting prognosis include:
* The presence of a pre-existing periapical lesion (bone infection).
* The quality of the final coronal seal (the filling/crown).
* The complexity of the root canal anatomy (e.g., curved canals or calcification).

==Complications==
* '''[[Sodium Hypochlorite Accident]]''': Extrusion of irritant past the apex.
* '''Instrument Separation''': A file breaking inside the canal.
* '''Perforation''': An accidental hole made through the side of the root.

==See Also==
* [[Endodontics]]
* [[Pulpitis]]

| image =
| caption = Application of fluoride varnish is a primary preventive measure.
| focus = Prevention of oral disease, maintenance of oral health, and patient education.
| related_fields = [[Dental Hygiene]], [[Dental Public Health]], [[Periodontology]]
}}

==Definition==
'''Preventive Dentistry''' is the branch of [[dentistry]] that focuses on procedures and life practices that help patients prevent the beginning or progression of oral disease. The goal is to maintain the natural dentition and supporting structures by preventing '''[[dental caries]]''', '''[[gingivitis]]''', and '''[[periodontitis]]'''.

Preventive dentistry is a collaborative effort between the dental professional (dentist and [[dental hygienist]]) and the patient.

==Levels of Prevention==
In public health and clinical practice, prevention is categorized into three levels:

===1. Primary Prevention===
Measures taken before any disease appears.
* '''[[Community Water Fluoridation]]''': Systemic mineral enrichment to strengthen developing enamel.
* '''[[Dental Sealants]]''': Plastic coatings applied to the pits and fissures of permanent molars to "seal out" bacteria.
* '''Dietary Counseling''': Reducing the frequency of fermentable carbohydrate intake to limit acid production by ''[[Streptococcus mutans]]''.

===2. Secondary Prevention===
Early detection and intervention to stop the progression of disease in its earliest stages.
* '''Routine Dental Exams''': Using [[radiology]] and visual inspection to find "incipient" (early) caries.
* '''[[Professional Prophylaxis]]''': Scaling and polishing to remove plaque and [[calculus]] (tartar) that the patient cannot remove at home.
* '''[[Fluoride Therapy]]''': High-concentration topical applications to promote '''remineralization''' of demineralized enamel.

===3. Tertiary Prevention===
Rehabilitative measures to replace lost tissues and restore function after significant disease has occurred.
* '''[[Dental Implants]]''' or '''[[Bridges]]''': To prevent the shifting of teeth and "collapse" of the bite after an extraction.
* '''[[Periodontal Surgery]]''': To prevent further bone loss in advanced cases.

==Home Care: The Patient's Role==
The "Medical Model" of preventive dentistry relies heavily on daily patient compliance:
* '''Mechanical Plaque Control''': Brushing twice daily with a soft-bristled toothbrush and daily interdental cleaning (flossing, interdental brushes).
* '''Chemotherapeutic Agents''': The use of toothpaste and mouthrinses containing '''[[Fluoride]]''', '''Xylitol''', or antimicrobial agents like '''Chlorhexidine'''.
* '''Habit Cessation''': Programs to stop tobacco use, which is a major risk factor for '''[[Oral Cancer]]''' and periodontal disease.

==Clinical Procedures==

* '''[[Prophylaxis]]''': The mechanical removal of biofilm and extrinsic stains.
* '''[[Caries Risk Assessment]] (CRA)''': A diagnostic tool used to categorize a patient’s risk level (Low, Moderate, High, Extreme) based on salivary flow, diet, and existing restorations.
* '''Oral Hygiene Instruction (OHI)''': Personalized coaching on brushing techniques (e.g., the Bass Method) and flossing.

==Economic Impact==
Preventive dentistry is highly cost-effective. Research consistently shows that every dollar spent on preventive measures (like water fluoridation or sealants) saves significantly more in future restorative and emergency dental costs.

==Definition==
'''Prosthodontics''' (also known as '''Dental Prosthetics''' or '''Prosthetic Dentistry''') is the dental specialty pertaining to the diagnosis, treatment planning, rehabilitation, and maintenance of the oral function, comfort, appearance, and health of patients with clinical conditions associated with missing or deficient teeth and/or oral and maxillofacial tissues using biocompatible substitutes.

A '''Prosthodontist''' is often considered the "architect" of a dental treatment plan, frequently coordinating with [[Periodontology|Periodontists]], [[Endodontics|Endodontists]], and [[Oral Surgery|Oral Surgeons]].

==Scope of Practice==
Prosthodontics is traditionally divided into four main sub-categories:

===1. Fixed Prosthodontics===
Restorations that are permanently attached to the teeth or implants and cannot be removed by the patient.
* '''[[Dental Crown]]''': A "cap" that covers a damaged tooth to restore its shape, size, and strength.
* '''[[Dental Bridge]]''' (Fixed Partial Denture): Replaces one or more missing teeth by anchoring to the adjacent natural teeth (abutments).
* '''[[Veneer]]''': A thin layer of porcelain or composite bonded to the facial surface of teeth for esthetic improvement.

===2. Removable Prosthodontics===
Prostheses that the patient can remove for cleaning and while sleeping.
* '''Complete Dentures''': Used when all teeth in an arch are missing.
* '''Removable Partial Dentures (RPD)''': Used when some natural teeth remain; these utilize clasps to stay in place.

===3. Implant Prosthodontics===
The restoration of '''[[Dental implants]]'''. This includes single crowns, implant-supported bridges, or "All-on-X" fixed hybrid proteheses where a full arch of teeth is supported by four to six implants.

===4. Maxillofacial Prosthetics===
A sub-specialty involved in treating patients with acquired or congenital defects of the head and neck (e.g., due to cancer surgery or trauma). This involves creating artificial eyes, ears, noses, or obturators to close defects in the [[palatine process|palate]].

==Materials in Prosthodontics==
Modern prosthodontics relies on a variety of high-tech materials:
* '''[[Zirconia]]''': Highly durable, tooth-colored ceramic used for crowns and bridges.
* '''Lithium Disilicate''' (e.g., e.max): Known for superior esthetics and translucency.
* '''[[Titanium]]''': The standard material for dental implant bodies due to its biocompatibility.
* '''[[Acrylic Resin]]''': The primary material for denture bases and teeth.

==The Digital Workflow==
The field has moved toward '''[[Digital Dentistry]]''', utilizing:
* '''Intraoral Scanners''': Replacing traditional "goopy" impressions with 3D digital models.
* '''[[CAD/CAM]]''': Computer-Aided Design and Manufacturing, allowing for the milling of crowns in-office or in a lab.
* '''3D Printing''': Used for creating surgical guides, models, and temporary prostheses.

==Professional Education==
To become a Board-Certified Prosthodontist:
# Earn a [[DDS]] or [[DMD]] degree.
# Complete a 36-month CODA-accredited residency.
# Achieve Diplomate status through the '''[[American Board of Prosthodontics]]''' (ABP).

}}

==Definition==
'''Periodontology''' (from Greek ''peri'' "around" and ''odous'' "tooth") is the specialty of [[dentistry]] that studies the supporting structures of teeth, as well as diseases and conditions that affect them. The supporting tissues are collectively known as the '''[[periodontium]]'''.

A '''Periodontist''' is a specialist who focuses on the prevention, diagnosis, and treatment of periodontal disease, and in the placement of [[dental implants]].

==The Periodontium==
The periodontium is composed of four main tissues:
# '''[[Gingiva]]''' (Gums): The visible soft tissue covering the alveolar bone.
# '''[[Periodontal Ligament]] (PDL)''': The connective tissue fibers that anchor the tooth to the bone and act as a shock absorber.
# '''[[Cementum]]''': The calcified layer covering the tooth root.
# '''[[Alveolar Bone]]''': The part of the jawbone that contains the tooth sockets.

==Periodontal Diseases==
Periodontal disease is typically an inflammatory response to the bacterial [[biofilm]] (plaque) on the teeth. It is broadly classified into two stages:

===1. Gingivitis===
The mildest form of periodontal disease.
* '''Symptoms''': Red, swollen, and bleeding gums.
* '''Reversibility''': Completely reversible with professional cleaning and good [[oral hygiene]].
* '''Bone loss''': No loss of supporting bone occurs in this stage.

===2. Periodontitis===
If gingivitis is left untreated, it can progress to periodontitis, where the inflammation spreads below the gum line.
* '''[[Periodontal Pocket]]''': The attachment between the tooth and gum breaks down, creating a space where bacteria thrive.
* '''Bone Destruction''': The body's immune response causes the breakdown of the alveolar bone.
* '''Classification''': Staged by severity (Stage I–IV) and graded by rate of progression (Grade A–C) according to the '''AAP/EFP 2017 Classification'''.

==Clinical Procedures==
Periodontists utilize both non-surgical and surgical interventions:

===Non-Surgical Therapy===
* '''[[Scaling and Root Planing]] (SRP)''': A deep cleaning that removes plaque and calculus from below the gum line and smoothes the root surfaces.
* '''Local Delivery Antimicrobials''': Placing antibiotics directly into periodontal pockets.

===Surgical Therapy===
* '''[[Flap Surgery]] (Pocket Reduction)''': Lifting the gums to remove deep tartar and suturing them back in a way that makes the area easier to clean.
* '''[[Soft Tissue Grafting]]''': Using tissue (from the palate or a donor) to cover exposed roots caused by '''[[gingival recession]]'''.
* '''[[Guided Tissue Regeneration]] (GTR)''': Using membranes and bone grafts to "regrow" lost bone and ligament.

==The Perio-Systemic Link==
Modern periodontology emphasizes the "Oral-Systemic Connection." Chronic periodontal inflammation is linked to several systemic conditions:
* '''[[Diabetes Mellitus]]''': A bidirectional relationship where uncontrolled diabetes worsens gum disease, and gum disease makes blood sugar harder to control.
* '''[[Cardiovascular Disease]]''': Increased risk of heart disease and stroke.
* '''Adverse Pregnancy Outcomes''': Potential links to low birth weight and preterm birth.

==Professional Education==
To become a Board-Certified Periodontist:
# Earn a [[DDS]] or [[DMD]] degree.
# Complete a 36-month CODA-accredited residency.
# Achieve Diplomate status through the '''[[American Board of Periodontology]]''' (ABP).

}}

==Definition==
'''Pediatric Dentistry''' is an age-defined specialty of [[dentistry]] that provides both primary and comprehensive preventive and therapeutic oral health care for infants and children through adolescence, including those with special health care needs.

A pediatric dentist is often referred to as the "pediatrician of dentistry," focusing on the unique physiological and psychological development of young patients.

==Scope of Practice==
The scope of pediatric dentistry is broad, encompassing growth and development, disease prevention, and restorative care:

===1. Preventive Care===
* '''[[Dental sealants]]''': Application of thin, protective coatings to the chewing surfaces of molars to prevent [[dental caries]].
* '''[[Fluoride therapy]]''': Professional application of fluoride varnish to strengthen developing [[enamel]].
* '''Nutrition Counseling''': Educating parents on the "caries-promoting" nature of sugary liquids and snacks.

===2. Management of Primary Dentition===
Treating "baby teeth" is critical as they maintain space for the permanent successors.
* '''[[Pulpotomy]]''': Often called a "baby root canal," this involves removing the infected coronal portion of the pulp.
* '''Stainless Steel Crowns (SSC)''': Durable, pre-formed crowns used to restore heavily decayed primary molars.
* '''Space Maintainers''': Appliances used to hold the gap open if a primary tooth is lost prematurely, preventing '''[[malocclusion]]'''.

===3. Growth and Development===
* Monitoring the transition from '''[[primary dentition]]''' to '''[[mixed dentition]]''' and finally '''[[permanent dentition]]'''.
* Early (Phase I) [[Orthodontics]] to intercept skeletal growth issues or deleterious habits like thumb-sucking.

===4. Behavior Guidance===
One of the most distinct aspects of the specialty is the use of psychological techniques to alleviate dental anxiety:
* '''Tell-Show-Do''': Explaining the procedure, showing the instrument, and then performing the task.
* '''Positive Reinforcement''': Rewarding desired behaviors to build trust.
* '''Pharmacological Support''': Use of [[Nitrous Oxide]] (laughing gas), conscious sedation, or general anesthesia for complex cases or highly anxious patients.

==Key Milestones in Pediatric Oral Health==
* '''The First Visit''': The American Academy of Pediatric Dentistry (AAPD) recommends the first dental visit by age one ("First visit by first birthday").
* '''Tooth Eruption''': Lower central incisors typically erupt between 6–10 months of age.
* '''Exfoliation''': The natural process of "losing" baby teeth, which usually begins around age 6.

==Special Health Care Needs (SHCN)==
Pediatric dentists receive specialized training to treat patients with physical, mental, sensory, or emotional impairments (e.g., [[Autism Spectrum Disorder]], [[Down Syndrome]], or [[Cerebral Palsy]]). This includes modifying the clinical environment and using specialized stabilization techniques.

==Professional Education==
To become a Board-Certified Pediatric Dentist:
# Earn a [[DDS]] or [[DMD]] degree.
# Complete a 24-month CODA-accredited residency.
# Achieve Diplomate status through the '''[[American Board of Pediatric Dentistry]]''' (ABPD).

}}

==Definition==
'''Oral and Maxillofacial Surgery (OMFS)''' is a globally recognized dental specialty that focuses on the diagnosis and surgical management of a wide range of diseases, injuries, and defects in the head, neck, face, jaws, and the hard and soft tissues of the oral and maxillofacial region.

Due to the complexity of the anatomical region, OMFS is considered the "bridge" between medicine and dentistry, often requiring practitioners to be proficient in both fields.

==Scope of Practice==
The scope of OMFS is broad, ranging from minor office-based procedures to major hospital-based reconstructive surgeries:

===1. Dentoalveolar Surgery===
The most common aspect of OMFS in daily practice.
* '''[[Tooth extraction]]''': Management of erupted, broken, or complex teeth.
* '''[[Impacted teeth]]''': Surgical removal of third molars (wisdom teeth) that are trapped under the bone or gingiva.
* '''[[Preprosthetic surgery]]''': Recontouring the [[alveolar process]] to prepare for [[dentures]] or implants.

===2. Dental Implantology===
* Placement of '''[[Dental implants]]''' to replace missing teeth.
* '''[[Bone grafting]]''': Procedures like sinus lifts or ridge augmentations to provide sufficient bone volume for implants.

===3. Orthognathic Surgery===
Corrective jaw surgery to fix skeletal deformities, malocclusion, and obstructive sleep apnea. This involves surgically repositioning the '''[[maxilla]]''' or '''[[mandible]]''' to achieve functional and esthetic balance.

===4. Trauma Surgery===
Treatment of acute injuries to the facial skeleton and soft tissues.
* Repair of facial lacerations.
* Reduction and fixation of fractures (e.g., mandibular, maxillary, zygomatic, or orbital fractures).

===5. Pathology and Oncology===
* Surgical management of benign and malignant tumors of the oral cavity (e.g., [[Squamous cell carcinoma]]).
* Treatment of [[Odontogenic tumors]] and cysts.
* Salivary gland surgery.

===6. Temporomandibular Joint (TMJ) Surgery===
Surgical intervention for severe '''[[TMJ]]''' disorders, ranging from arthroscopy (minimally invasive) to total joint replacement.

==Education and Training==
The training pathway for an Oral and Maxillofacial Surgeon is among the most rigorous in the healthcare professions:
# '''Dental School''': Completion of a [[DDS]] or [[DMD]] degree.
# '''Residency''': A 4-to-6-year hospital-based surgical residency.
#* '''4-Year Program''': Leads to a certificate in OMFS.
#* '''6-Year Program''': Includes the completion of a Medical Degree (MD) alongside the surgical certificate.
# '''Fellowship''' (Optional): Further specialization in areas like Pediatric Maxillofacial Surgery or Head and Neck Oncology.

==Clinical Techniques==
* '''[[Intravenous Sedation]] and General Anesthesia''': OMFS is the only dental specialty where practitioners are extensively trained to administer deep sedation and general anesthesia in an office setting.
* '''[[Guided Surgery]]''': Using 3D imaging ([[CBCT]]) and CAD/CAM technology to plan implants and jaw movements with sub-millimeter precision.

}}

==Definition==
'''Oral and Maxillofacial Radiology''' is the specialty of [[dentistry]] concerned with the prescription, production, and interpretation of images produced by all modalities of radiant energy. These images are used for the diagnosis and management of diseases, disorders, and conditions of the [[oral cavity]] and the [[maxillofacial]] region.

==Imaging Modalities==
OMFR has evolved from traditional silver-halide film to advanced digital 3D imaging:

===1. Intraoral Radiography===
The most common imaging used in daily practice, where the sensor is placed inside the mouth.
* '''[[Periapical Radiograph]] (PA)''': Shows the entire tooth from crown to the apex of the root and surrounding bone.
* '''[[Bitewing Radiograph]] (BW)''': Primarily used to detect interproximal [[dental caries]] and evaluate alveolar bone levels.
* '''[[Occlusal Radiograph]]''': Used to view larger areas of the floor of the mouth or the palate.

===2. Extraoral Radiography===
The sensor is located outside the patient's head.
* '''[[Panoramic Radiograph]] (Orthopantomogram/OPG)''': Provides a wide-angle view of the entire maxilla, mandible, and [[temporomandibular joint]].
* '''[[Cephalometric Analysis]]''': Standardized lateral views used primarily in '''[[Orthodontics]]''' to measure skeletal relationships.

===3. Advanced 3D Imaging===
* '''[[Cone Beam Computed Tomography]] (CBCT)''': The "gold standard" for modern dental imaging. Unlike medical CT, it uses a cone-shaped beam to reduce radiation dose while providing high-resolution 3D data.
* '''[[Magnetic Resonance Imaging]] (MRI)''': Used specifically for soft tissue evaluation, such as the articular disc in the [[TMJ]].

==Diagnostic Interpretation==
A radiologist looks for specific "radiographic signs" to categorize lesions:
* '''Radiolucency''': Dark areas indicating a loss of density (e.g., [[Abscess]], [[Cyst]], or [[Caries]]).
* '''Radiopacity''': Light areas indicating dense material (e.g., [[Enamel]], [[Fillings]], or [[Osteoma]]).
* '''Mixed Lesions''': Containing both light and dark components (e.g., [[Calcifying Epithelial Odontogenic Tumor]]).

==Radiation Safety and Biology==
A core responsibility of the OMFR specialist is the application of the '''ALARA Principle''' (As Low As Reasonably Achievable).
* '''[[Dosimetry]]''': Measuring the "effective dose" to the patient.
* '''Lead Shielding''': The use of thyroid collars and aprons to protect radiosensitive tissues.
* '''Digital Sensors''': These require significantly less radiation than traditional film (up to 80% reduction).

==Professional Education==
To become a Board-Certified Oral and Maxillofacial Radiologist:
# Earn a [[DDS]] or [[DMD]] degree.
# Complete a 24 to 36-month CODA-accredited residency.
# Pass the examination of the '''[[American Board of Oral and Maxillofacial Radiology]]''' (ABOMR).

}}

==Definition==
'''Oral and Maxillofacial Pathology''' (also known as '''Oral Pathology''') is the specialty of [[dentistry]] and [[pathology]] that investigates the causes, processes, and effects of diseases affecting the oral cavity, jaws, and associated structures (such as salivary glands and facial muscles).

It is a "bridge" specialty that links basic clinical science to patient care through the definitive diagnosis of biopsies and surgical specimens.

==The Diagnostic Process==
Oral pathologists utilize a combination of clinical, radiographic, and microscopic data to reach a diagnosis:

===1. Clinical Correlation===
The pathologist evaluates the "clinical presentation":
* '''Location''': e.g., lateral border of the tongue vs. hard palate.
* '''Morphology''': Is the lesion a [[macule]], [[papule]], [[vesicle]], or [[ulcer]]?
* '''Symptoms''': Is it asymptomatic or painful?

===2. Radiographic Interpretation===
For lesions within the [[maxilla]] or [[mandible]], imaging (Periapical, Panoramic, or [[CBCT]]) is essential.
* '''Radiolucent''': Dark areas indicating bone destruction (e.g., [[Dentigerous cyst]]).
* '''Radiopaque''': Light areas indicating mineralized tissue (e.g., [[Odontoma]]).

===3. Histopathology===
The "gold standard" of diagnosis. Tissue is obtained via [[biopsy]], processed into slides, and stained (most commonly with '''[[Hematoxylin and Eosin]]''' or H&E).
* '''[[Incisional biopsy]]''': Taking a representative sample of a large lesion.
* '''[[Excisional biopsy]]''': Removal of the entire lesion.

==Key Areas of Study==

===Odontogenic Lesions===
Unique to the jaws, these arise from the tissues that form teeth (dental lamina, enamel organ).
* '''Cysts''': [[Radicular cyst]], [[Odontogenic Keratocyst]] (OKC).
* '''Tumors''': [[Ameloblastoma]], [[Ameloblastic fibroma]].

===Mucosal Pathology===
Diseases of the [[oral mucosa]], ranging from viral infections to auto-immune conditions.
* '''Infectious''': [[Candidiasis]], [[Herpes Simplex]].
* '''Immune-mediated''': [[Pemphigus vulgaris]], [[Lichen planus]].

===Oral Malignancy===
The study of '''[[Oral Cancer]]'''. The most prevalent form is '''[[Squamous Cell Carcinoma]]''', which accounts for over 90% of all oral cancers. Pathologists play a critical role in "grading" (degree of cell differentiation) and "staging" (extent of spread).

==Professional Education==
To become a Board-Certified Oral and Maxillofacial Pathologist, a practitioner must:
# Earn a [[DDS]] or [[DMD]] degree.
# Complete a 36-month CODA-accredited residency program.
# Pass the examination of the '''[[American Board of Oral and Maxillofacial Pathology]]''' (ABOMP) or equivalent national body.

| related_fields = [[Epidemiology]], [[Preventive Dentistry]], [[Health Economics]]
}}

==Definition==
'''Dental Public Health (DPH)''' is a non-clinical specialty of [[dentistry]] involved in the assessment of dental health needs and the implementation of solutions to improve the dental health of populations rather than individuals.

The '''[[American Board of Dental Public Health]]''' defines it as "the science and art of preventing and controlling dental diseases and promoting dental health through organized community efforts."

==Core Functions==
DPH professionals typically operate based on three core pillars of public health:

===1. Assessment===
* '''[[Epidemiology]]''': Monitoring the prevalence and incidence of oral diseases (e.g., [[dental caries]] and [[periodontitis]]) within a specific demographic.
* '''Surveillance''': Tracking oral health trends over time to identify emerging disparities.

===2. Policy Development===
* Advocating for legislation that promotes oral health, such as taxes on sugar-sweetened beverages or mandatory dental screenings for schoolchildren.
* Establishing clinical guidelines and standards of care for public clinics.

===3. Assurance===
* Ensuring that the community has access to cost-effective and high-quality oral healthcare.
* Managing public dental programs and community health centers.

==Key Interventions==
DPH is most notable for large-scale preventive measures that do not require individual clinical visits:

* '''[[Water Fluoridation]]''': The adjustment of fluoride in community water supplies to a level optimal for preventing tooth decay. It is considered one of the "10 Great Public Health Achievements of the 20th Century."
* '''School-based Sealant Programs''': Providing [[dental sealants]] to children in high-risk areas.
* '''Tobacco Cessation Programs''': Targeting oral cancer prevention through community-wide education.

==The Social Determinants of Oral Health==
DPH practitioners study how non-medical factors influence dental outcomes:
* '''Socioeconomic Status (SES)''': The correlation between income level and access to restorative care.
* '''Health Literacy''': A patient's ability to understand and act upon oral hygiene instructions.
* '''Geographic Access''': The challenge of "dental deserts" in rural or underserved urban areas.

==Professional Career Path==
To become a '''[[Public Health Dentist]]''', a practitioner usually follows this path:
# Obtain a [[DDS]], [[DMD]], or [[BDS]] degree.
# Complete a **Master of Public Health (MPH)** or a Master of Science in Dental Public Health (MSDPH).
# Complete a residency program in Dental Public Health.
# Achieve Board Certification (e.g., Diplomate of the ABDPH).

| equivalence = [[Doctor of Dental Surgery]] (DDS) / [[Doctor of Medicine in Dentistry]] (DMD)
| latin_name = Baccalaureus Chirurgiae Dentalis
}}

==Overview==
The '''Bachelor of Dental Surgery (BDS or BChD)''' is a professional degree in [[dentistry]] awarded by universities in the United Kingdom, Ireland, Australia, New Zealand, India, Pakistan, and many other Commonwealth countries.

Unlike the North American [[DDS]]/[[DMD]] model, which is a post-graduate "professional doctorate" (requiring a prior 4-year bachelor's degree), the BDS is typically an '''undergraduate-entry''' professional degree. Despite the "Bachelor" title, it is the primary clinical qualification that allows a practitioner to register as a [[dentist]].

==Educational Structure==
The BDS curriculum generally spans five to six years. Because students enter directly from secondary school, the program integrates basic sciences with clinical training from the outset.

# '''Pre-clinical Years (1–2)''': Focus on Human [[Anatomy]], [[Physiology]], [[Biochemistry]], and [[Oral Biology]]. Students begin "phantom head" (simulation) labs to learn operative techniques.
# '''Clinical Years (3–5)''': Students transition to treating patients in a hospital or university clinic setting, covering specialties such as [[Periodontology]], [[Prosthodontics]], and [[Oral Surgery]].
# '''Foundation Training (Post-graduation)''': In many jurisdictions (like the UK's NHS), a newly qualified BDS must complete a year of supervised "Vocational Training" or "Foundation Training" before practicing independently.

==Nomenclature Variations==
While '''BDS''' is the most common abbreviation, some prestigious universities use alternative Latin-based titles:
* '''BChD''': ''Baccalaureus Chirurgiae Dentalis'' (University of Leeds).
* '''BDentSc''': ''Baccalaureus in Dentaria Scientia'' (Trinity College Dublin).
* '''BDS (Adel)''', '''BDS (Syd)''': Often followed by the university's abbreviation in brackets to denote the granting institution.

==Global Equivalence and the "Doctor" Title==
A common point of confusion is the professional title used by BDS holders:
* '''Clinical Parity''': The [[World Health Organization]] (WHO) and the [[FDI World Dental Federation]] recognize the BDS as clinically equivalent to the DDS and DMD.
* '''The Title "Doctor"''': Historically, BDS dentists in the UK and Australia did not use the title "Doctor" (as they were technically "Mr." or "Ms." surgeons). However, in recent decades, regulatory bodies (such as the GDC in the UK and AHPRA in Australia) have permitted BDS holders to use the courtesy title '''"Dr."''' to align with international standards and patient expectations.

==Licensure and Registration==
To practice, a BDS graduate must register with their national dental board:
* '''United Kingdom''': General Dental Council (GDC).
* '''Australia''': Dental Board of Australia (AHPRA).
* '''India''': Dental Council of India (DCI).
* '''Overseas Practitioners''': A BDS holder moving to the USA must usually complete a 2-year "International Dentist Program" (IDP) to earn a DDS/DMD before they can be licensed in most states.

==Overview==
The '''Doctor of Medicine in Dentistry (DMD)''' is a professional doctoral degree awarded to clinicians upon the completion of a four-year dental curriculum. In the United States and Canada, the DMD is functionally and academically identical to the [[Doctor of Dental Surgery]] (DDS).

The choice between awarding a DDS or a DMD is entirely a matter of institutional preference by the granting university. Both degrees signify that the recipient has met the national standards for clinical competency and is eligible for licensure as a general [[dentist]].

==The Harvard Origin (Etymology)==
The existence of two different titles for the same profession is rooted in 19th-century academic tradition.
* In 1867, '''[[Harvard University]]''' established its dental school.
* Harvard's policy required all degree titles to be expressed in Latin.
* The Latin translation of "Doctor of Dental Surgery" (''Chirurgae Dentium Doctor'') was considered ungrammatical or phonetically displeasing by the faculty.
* They instead created the title '''Dentariae Medicinae Doctor''' (Doctor of Dental Medicine), abbreviated as **DMD**.

Since that time, many other universities—particularly those with a strong emphasis on the medical integration of dentistry—have adopted the DMD title.

==Curriculum and Standards==
All DMD programs in North America must be accredited by the '''Commission on Dental Accreditation (CODA)'''. The curriculum typically mirrors that of a DDS program:

# '''Didactic Science (Years 1-2)''': Focuses on Gross [[Anatomy]], [[Histology]], [[Pharmacology]], [[Pathology]], and [[Biochemistry]].
# '''Pre-clinical Simulation''': Students practice restorative techniques on manikins (typodonts) before entering the clinic.
# '''Clinical Rotations (Years 3-4)''': Hands-on patient care involving [[Oral Diagnosis]], [[Radiology]], [[Periodontology]], and [[Oral Surgery]].

==Professional Recognition==
The '''[[American Dental Association]] (ADA)''' explicitly states that there is no difference between the two degrees:
<blockquote>"The DDS and DMD are the same degrees. They use the same curriculum requirements set by the Commission on Dental Accreditation (CODA). The difference is only in the name of the degree."</blockquote>

Regardless of whether a practitioner holds a DDS or a DMD, they are entitled to use the prefix "Dr." and are referred to as a "Dentist."

==International Variations==
While the DMD is standard in the U.S. and Canada, other countries use different nomenclature for the same level of training:
* '''[[Bachelor of Dental Surgery]] (BDS)''': The standard in the United Kingdom, Australia, and much of the Commonwealth.
* '''[[Stomatologist]]''': Often used in European countries where the degree is closely tied to general medicine (MD).

}}

==Overview==
The '''Doctor of Dental Surgery (DDS)''' is a professional doctoral degree awarded to individuals who have completed a recognized program of study in [[dentistry]]. It is one of the two primary degrees (alongside the [[DMD]]) that qualifies a person to practice as a general [[dentist]] in the United States, Canada, and several other jurisdictions.

While the titles differ in name, the '''[[American Dental Association]] (ADA)''' and the '''Commission on Dental Accreditation (CODA)''' treat the DDS and DMD as academically and clinically equivalent.

==History and Nomenclature==
The DDS is the older of the two titles, first awarded by the '''[[Baltimore College of Dental Surgery]]''' in 1840—the world's first dental school.

The alternative title, [[Doctor of Medicine in Dentistry]] (DMD), was created in 1867 by [[Harvard University]]. Harvard, which traditionally granted degrees in Latin, translated "Doctor of Dental Surgery" into ''Chirurgae Dentium Doctor'', but found it linguistically awkward. They instead opted for ''Dentariae Medicinae Doctor'' (DMD). Since then, universities have chosen between the two based on institutional tradition.

==Educational Requirements==
In North America, obtaining a DDS typically requires a minimum of eight years of post-secondary education:

===1. Undergraduate Preparation===
* Completion of a Bachelor's degree with a heavy emphasis on science (Biology, General Chemistry, Organic Chemistry, Physics, and Biochemistry).
* Achievement of a competitive score on the '''[[Dental Admission Test]] (DAT)'''.

===2. Dental School Curriculum===
* '''Years 1–2 (Pre-clinical)''': Intensive study of biomedical sciences (Anatomy, Biochemistry, Physiology, Microbiology, and Pharmacology) and "simulation lab" training in operative dentistry.
* '''Years 3–4 (Clinical)''': Direct patient care under faculty supervision in a dental clinic, rotating through specialties such as [[Endodontics]], [[Periodontology]], and [[Oral Surgery]].

==Licensure and Practice==
Earning a DDS degree is the academic requirement for licensure, but it does not automatically grant the right to practice. Candidates must also pass:
* '''[[Integrated National Board Dental Examination]] (INBDE)''': A comprehensive written exam covering clinical and basic sciences.
* '''Regional Clinical Exams''': Hands-on exams (e.g., ADEX, WREB) involving procedures on manikins or live patients.
* '''Jurisprudence Exam''': A test of the specific dental laws in the practitioner's state or province.

==Specialization==
Upon receiving a DDS, a dentist may practice as a general practitioner or apply for a residency to specialize in one of the twelve recognized dental specialties, such as [[Orthodontics]] or [[Prosthodontics]]. These programs typically lead to a '''Master of Science (MS)''' or a '''Certificate of Specialty Training'''.

| known_for = Author of ''Le Chirurgien Dentiste''; defining dentistry as a scientific discipline.
}}

==Introduction==
'''Pierre Fauchard''' (1678 – March 22, 1761) was a French physician and surgeon, widely considered the "Father of Modern Dentistry." He is credited with transforming dentistry from a trade practiced by "tooth-pullers" and barbers into a scientific medical profession.

His seminal work, '''''Le Chirurgien Dentiste''''' (''The Surgeon Dentist''), published in 1728, provided the first systematic clinical description of dental anatomy, operative techniques, and [[prosthodontics]].

==Early Life and Career==
Fauchard was born in Brittany and joined the French Royal Navy at age 15. It was there that he encountered the scurvy-related oral diseases common among sailors. Under the mentorship of Alexander Poteleret, a surgeon-major, Fauchard began documenting his observations of the [[oral cavity]] and the effects of malnutrition on the [[periodontium]].

By the early 18th century, he established a practice in Paris, where he broke the tradition of "trade secrets" by openly sharing his surgical techniques and instrument designs with colleagues.

==Le Chirurgien Dentiste (1728)==
This two-volume treatise was a revolutionary document that challenged medieval dental myths.
* '''Rejection of the "Tooth Worm":''' Fauchard was among the first to argue that [[dental caries]] were not caused by worms, but by sugar consumption and chemical processes.
* '''Clinical Documentation:''' He provided detailed instructions on how to treat caries, perform [[tooth extraction]], and manage [[periodontal disease]].
* '''Ergonomics:''' He was the first to suggest that the patient should sit in a dedicated, upholstered chair rather than on the floor or in the lap of an assistant.

==Major Contributions to Dentistry==

===1. Prosthodontics===
Fauchard pioneered the use of '''[[dental bridges]]''' and early '''[[dentures]]'''. He used carved ivory and bone, often held in place by springs made of steel or whalebone. He also experimented with using human teeth (transplants) and artificial enamels to improve esthetics.

===2. Orthodontics===
He is credited with the invention of the '''Bandeau''', a horseshoe-shaped strip of gold or silver that was tied to the teeth with silk threads to expand the [[dental arch]] and align crowded teeth—the precursor to modern [[orthodontic appliances]].

===3. Operative Dentistry===
Fauchard introduced several specialized '''[[dental instruments]]''', adapting

| Articulation = [[Condylar process]] of the [[mandible]], [[Mandibular fossa]] of the [[temporal bone]]
| Nerve = [[Auriculotemporal nerve]], [[Masseteric nerve]]
}}

==Definition==
The '''temporomandibular joint (TMJ)''' is the bilateral [[synovial joint]] that articulates the [[mandible]] (lower jaw) to the [[temporal bone]] of the [[skull]]. It is unique in the human body as a '''ginglymoarthrodial joint''', meaning it allows for both hinging (rotation) and gliding (translation) movements.

The two joints must function in unison to facilitate [[mastication]], speech, and yawning.

==Anatomy and Structure==

===1. Articular Surfaces===
* '''Mandibular Condyle''': The superior-posterior part of the mandibular ramus.
* '''Mandibular Fossa''' (Glenoid Fossa): The depression in the temporal bone.
* '''Articular Eminence''': The raised bony projection anterior to the fossa that guides the condyle during translation.

===2. The Articular Disc (Meniscus)===
The TMJ is divided into upper and lower compartments by a biconcave '''articular disc''' made of dense [[fibrocartilage]] (unlike most synovial joints which use hyaline cartilage).
* The disc is avascular and non-innervated in its central load-bearing zone.
* It is attached posteriorly to the '''retrodiscal tissue''' (bilaminar zone), which is highly vascular and innervated.

===3. Ligaments===
The joint is stabilized by several key ligaments:
* '''Temporomandibular (Lateral) ligament''': Prevents excessive posterior and lateral displacement.
* '''Sphenomandibular ligament''': An accessory ligament.
* '''Stylomandibular ligament''': Limits excessive protrusion of the mandible.

==Biomechanics and Movement==
TMJ movement occurs in two distinct phases:
# '''Rotation (Hinging)''': Occurs in the '''lower compartment''' (between the condyle and the disc) during the first 20–25 mm of mouth opening.
# '''Translation (Gliding)''': Occurs in the '''upper compartment''' (between the disc and the temporal bone) as the condyle moves forward down the articular eminence for wide opening.

==Clinical Significance==

===Temporomandibular Disorders (TMD)===
TMD is a broad term encompassing pain and dysfunction of the TMJ and the [[masticatory muscles]].
* '''Internal Derangement''': Most commonly '''[[Disc Displacement with Reduction]]''', characterized by a "click" or "pop" as the disc snaps back into position during opening.
* '''Disc Displacement without Reduction''': Often leads to "closed lock," where the patient has limited opening because the disc acts as an obstruction.

===Dislocation (Subluxation)===
Occurs when the condyle moves anteriorly past the articular eminence and becomes trapped, preventing the patient from closing their mouth.

===Bruxism===
Chronic grinding or clenching can lead to flattening of the condyle, perforation of the disc, or hypertrophy of the associated muscles (e.g., [[masseter muscle]]).

}}

==Definition==
'''Stomatology''' (from Greek ''stoma'' "mouth" and ''logos'' "study") is the branch of [[medicine]] concerned with the study of the structures, functions, and diseases of the [[oral cavity]] and the associated structures of the [[maxillofacial]] region.

In a modern clinical context, stomatology bridges the gap between traditional [[dentistry]] and [[internal medicine]], focusing on the oral manifestations of systemic diseases and the medical management of non-tooth-related pathologies.

==Scope of Practice==
While the term is often used interchangeably with dentistry, stomatology typically emphasizes:
* '''[[Oral Medicine]]''': The non-surgical management of chronic conditions such as [[xerostomia]], [[oral lichen planus]], and [[burning mouth syndrome]].
* '''Systemic Correlation''': Diagnosis of systemic conditions that present with oral symptoms, such as [[Crohn's disease]], [[leukemia]], and [[HIV/AIDS]].
* '''[[Oral Pathology]]''': The microscopic study and clinical diagnosis of oral tumors and cysts.
* '''Orofacial Pain''': Management of complex pain conditions, including [[Temporomandibular joint|TMJ disorders]] and [[trigeminal neuralgia]].

==International Perspective==
The terminology and educational pathways for stomatology vary globally:
* '''European/Latin American Model''': In many countries (e.g., Italy, Spain, Russia, China), stomatology is a specialized branch of medicine. Practitioners often hold a medical degree (MD) before specializing in the mouth.
* '''North American Model''': The term is less common; "Oral Medicine" is the preferred sub-specialty, practiced by dentists (DDS/DMD) who have completed postgraduate residency.

==Common Stomatological Conditions==
Stomatologists treat conditions that fall outside the scope of traditional restorative dentistry:
# '''[[Vesiculobullous diseases]]''': Such as [[Pemphigus vulgaris]] and [[Mucous membrane pemphigoid]].
# '''[[Infectious diseases]]''': Including [[Candidiasis]] (thrush) and [[Herpes Simplex Virus]] (HSV).
# '''[[Potentially Malignant Disorders]]''': Such as [[Leukoplakia]] and [[Erythroplakia]].
# '''[[Salivary Gland Pathology]]''': Including [[Sialadenitis]] and [[Sjogren's syndrome]].

==History==
The term gained prominence in the late 19th and early 20th centuries as practitioners sought to integrate dental surgery into the broader field of medicine. In 1907, the International Stomatological Association (ASI) was founded to promote the medical education of dentists.

| Function = Production of [[saliva]], lubrication, initial [[digestion]], and tooth protection.
}}

==Definition==
'''Salivary glands''' are [[exocrine glands]] in the [[oral cavity]] that produce and secrete '''[[saliva]]'''. Saliva contains enzymes (like [[amylase]]) that begin the breakdown of carbohydrates, as well as mucus, electrolytes, and antimicrobial agents that maintain oral health.

The salivary system is divided into two main groups: the three pairs of **major salivary glands** and hundreds of **minor salivary glands**.

==Major Salivary Glands==

===1. Parotid Gland===
The largest of the salivary glands, located bilaterally in the pre-auricular region (in front of the ears).
* '''Secretory type''': Purely '''serous''' (watery) secretion.
* '''Duct''': '''[[Parotid duct]]''' (Stensen's duct), which opens into the oral vestibule opposite the maxillary second molar.
* '''Innervation''': Secretomotor supply from the '''[[Glossopharyngeal nerve]]''' (CN IX).
* '''Clinical Note''': The '''[[facial nerve]]''' (CN VII) passes through the gland but does not innervate it.

===2. Submandibular Gland===
Located in the submandibular triangle, medial to the body of the [[mandible]].
* '''Secretory type''': Mixed, but predominantly '''serous'''.
* '''Duct''': '''[[Submandibular duct]]''' (Wharton's duct), which opens at the sublingual caruncle at the base of the tongue.
* '''Innervation''': Secretomotor supply from the '''[[Facial nerve]]''' (CN VII) via the chorda tympani.

===3. Sublingual Gland===
The smallest of the major glands, located in the floor of the mouth, superior to the mylohyoid muscle.
* '''Secretory type''': Mixed, but predominantly '''mucous''' (thick).
* '''Duct''': Multiple small ducts (ducts of Rivinus) and the major sublingual duct (Bartholin's duct).
* '''Innervation''': Same as the submandibular gland (CN VII).

==Minor Salivary Glands==
There are 600 to 1,000 minor salivary glands distributed throughout the [[oral mucosa]] (except the anterior hard palate and gingiva). They are primarily mucous-secreting and provide continuous lubrication.

==Microscopic Anatomy==
The functional unit of a salivary gland is the '''[[salivon]]''', which consists of:
* '''Acinus''': A cluster of cells that produce the primary secretion.
* '''Intercalated duct''': Short duct leading from the acinus.
* '''Striated duct''': Involved in the reabsorption of sodium and secretion of potassium, making saliva '''hypotonic'''.
* '''Excretory duct''': The final path to the oral cavity.

==Clinical Significance==
* '''[[Sialolithiasis]]''': The formation of "salivary stones," most common in Wharton's duct due to the upward flow and high calcium content of submandibular saliva.
* '''[[Xerostomia]]''': The subjective feeling of dry mouth, often a side effect of medications or '''[[Sjogren's syndrome]]'''.
* '''[[Mucocele]]''': A common lesion caused by the rupture of a minor salivary gland duct, leading to mucus extravasation into the tissue.
* '''[[Pleomorphic Adenoma]]''': The most common benign tumor of the salivary glands, usually occurring in the parotid.

}}

==Definition==
The '''mandible''' is the horseshoe-shaped bone that forms the lower jaw and holds the lower [[teeth]]. It consists of a horizontal portion, the '''body''', and two vertical portions, the '''rami''' (singular: ramus), which articulate with the [[temporal bone]] to form the [[temporomandibular joint]] (TMJ).

Unlike the [[maxilla]], which is fused to the skull, the mandible is a movable structure essential for [[mastication]], [[speech]], and facial expression.

==Anatomical Features==

===1. The Body of the Mandible===
The horizontal part of the bone that supports the lower dentition.
* '''[[Alveolar process]]''': The superior margin containing the sockets for the mandibular teeth.
* '''Mental Foramen''': An opening typically located below the second [[premolar]] that transmits the [[mental nerve]] and vessels.
* '''Mental Protuberance''': The bony prominence forming the chin.
* '''Mylohyoid Line''': A ridge on the internal surface where the [[mylohyoid muscle]] attaches, forming the floor of the mouth.

===2. The Ramus===
The vertical part of the mandible that extends upward.
* '''[[Condylar process]]''': The posterior projection that articulates with the glenoid fossa of the temporal bone.
* '''[[Coronoid process]]''': The anterior projection that serves as the attachment point for the [[temporalis muscle]].
* '''Mandibular Notch''': The depression between the condylar and coronoid processes.
* '''Mandibular Foramen''': Located on the internal (medial) surface of the ramus; it is the entry point for the [[inferior alveolar nerve]].

===3. The Angle of the Mandible===
The junction where the inferior border of the body meets the posterior border of the ramus. It is a major attachment site for the [[masseter muscle]] and [[medial pterygoid muscle]].

==Clinical Significance==

===Local Anesthesia===
The '''[[Inferior Alveolar Nerve Block]] (IANB)''' is the most common anesthetic

| System = [[Skeletal system]]
| Articulation = [[Frontal bone]], [[Ethmoid bone]], [[Nasal bone]], [[Zygomatic bone]], [[Palatine bone]], [[Vomer]]
}}

==Definition==
The '''maxilla''' (plural: '''maxillae''') is a vital viscerocranium bone that forms the upper jaw. It holds the upper [[teeth]], forms the boundaries of three cavities (the roof of the [[oral cavity]], the floor and lateral wall of the [[nasal cavity]], and the floor of the [[orbit]]), and contains the largest of the paranasal sinuses.

The two maxillae fuse at the **intermaxillary suture** during embryonic development to form the upper jaw skeleton.

==Anatomical Parts==
The maxilla consists of a central body and four projections known as processes:

===1. The Body of the Maxilla===
The pyramid-shaped central portion containing the '''[[maxillary sinus]]''' (Antrum of Highmore).
* '''Infraorbital foramen''': Located on the anterior surface, transmitting the infraorbital nerve and vessels.
* '''Maxillary tuberosity''': A rounded eminence on the posterior surface, located distally to the third molar; an important landmark for [[local anesthesia]] (PSA nerve block).

===2. The Four Processes===
* '''[[Alveolar process]]''': The thickest part of the bone, containing the dental sockets ([[dental alveoli]]) for the maxillary teeth.
* '''[[Zygomatic process]]''': Points laterally to articulate with the [[zygomatic bone]] (cheekbone).
* '''[[Frontal process]]''': Extends upward to articulate with the [[frontal bone]], forming part of the lateral boundary of the nose.
* '''[[Palatine process]]''': A horizontal projection that forms the anterior three-quarters of the [[hard palate]].

==Clinical Significance==
The maxilla is of paramount importance in several dental specialties:

===Sinus Proximity===
The roots of the maxillary [[molars]] and [[premolars]] are often in close proximity to the floor of the '''[[maxillary sinus]]'''.
* '''[[Oroantral communication]]''': A potential complication after extraction where a hole is created between the mouth and the sinus.
* '''[[Sinus lift]]''': A surgical procedure to increase bone volume in the posterior maxilla for [[dental implant]] placement.

===Le Fort Fractures===
In oral and maxillofacial surgery, the maxilla is the site of classic "Le Fort" midface fractures:
* '''Le Fort I''': Horizontal fracture above the alveolar process (floating palate).
* '''Le Fort II''': Pyramidal fracture involving the nasal bones and orbital floor.
* '''Le Fort III''': Complete craniofacial dysjunction.

===Orthodontics===
The maxilla can be expanded using a '''[[Rapid Palatal Expander]] (RPE)''' by opening the mid-palatal suture, typically in growing patients.

| Image =
| Caption = Histological cross-section showing the epithelium, basement membrane, and lamina propria.
| System = [[Exocrine system]], [[Digestive system]]
| Component = [[Stratified squamous epithelium]], [[Lamina propria]]
}}

==Definition==
The '''oral mucosa''' is the mucous membrane lining the inside of the [[oral cavity]]. It consists of '''[[stratified squamous epithelium]]''' and an underlying connective tissue called the '''[[lamina propria]]'''. In certain areas, it is supported by a deeper '''submucosa'''.

The oral mucosa serves as a primary barrier against mechanical trauma, microorganisms, and toxic substances, while also providing sensory information (touch, temperature, and [[taste]]).

==Classification by Function==
The oral cavity is not uniform; the mucosa is specialized based on the mechanical stress it endures:

===1. Masticatory Mucosa===
This mucosa is designed to withstand the forces of [[mastication]] (chewing). It is typically '''keratinized''' or '''parakeratinized'''.
* '''Locations''': [[Hard palate]] and [[Attached gingiva]].
* '''Characteristics''': Firmly bound to the underlying bone (mucoperiosteum); lacks a submucosa in most areas.

===2. Lining Mucosa===
The most common type, providing flexibility for speech and swallowing. It is '''non-keratinized'''.
* '''Locations''': [[Buccal mucosa]] (cheeks), [[labial mucosa]] (lips), [[floor of the mouth]], ventral surface of the [[tongue]], and [[soft palate]].
* '''Characteristics''': Soft, moist, and elastic; usually has a well-developed submucosa containing [[minor salivary glands]].

===3. Specialized Mucosa===
Found specifically on the dorsal (top) surface of the '''[[tongue]]'''.
* '''Characteristics''': Contains both keratinized and non-keratinized areas and is characterized by the presence of '''[[lingual papillae]]''' and '''[[taste buds]]'''.

==Microscopic Structure==
The oral mucosa is composed of several distinct layers:
# '''Epithelium''': Stratified squamous type. It can be orthokeratinized (no nuclei in the top layer), parakeratinized (shrunken nuclei present), or non-keratinized.
# '''Basement Membrane''': The interface between the epithelium and connective tissue.
# '''Lamina Propria''': A layer of connective tissue containing blood vessels, nerves, and collagen fibers. It is divided into the papillary layer and the reticular layer.
# '''Submucosa''' (where present): Contains larger blood vessels, nerves, and adipose tissue or salivary glands.

==Clinical Significance==
* '''[[Permeability]]''': The lining mucosa (especially under the tongue) is highly permeable, allowing for '''sublingual administration''' of medications (e.g., nitroglycerin).
* '''[[Fordyce granules]]''': Ectopic sebaceous glands commonly found in the buccal mucosa; considered a variation of normal.
* '''[[Lineal alba]]''': A white line on the buccal mucosa caused by frictional keratinization from the teeth.
* '''[[Oral Lichen Planus]]''': A common chronic inflammatory condition affecting the oral mucosa.

==Introduction==
'''Teeth''' (singular: '''tooth''') are hard, mineralized structures found in the [[alveolar process|alveolar arches]] of the [[maxilla]] and [[mandible]]. Unlike bone, teeth are not technically part of the skeletal system; they are considered specialized organs of the [[integumentary system]] that have evolved for the mechanical breakdown of food ([[mastication]]) and to facilitate [[speech]].

==Anatomical Structure==
A tooth is divided into two primary parts:
* '''Crown''': The visible portion of the tooth above the [[gingival margin]].
* '''Root''': The portion embedded within the alveolar bone, anchored by the [[periodontal ligament]].
* '''Cervix (Neck)''': The slight constriction at the junction of the crown and the root ([[Cementoenamel junction]]).

===Tissue Layers===
A tooth is composed of four distinct tissues:
# '''[[Enamel]]''': The hardest substance in the human body. It is highly mineralized (96% hydroxyapatite) and covers the crown. It is non-vital and cannot regenerate.
# '''[[Dentin]]''': Located beneath the enamel and cementum. It is a vital, mineralized tissue that contains microscopic '''[[dentinal tubules]]'''.
# '''[[Dental pulp]]''': The unmineralized central chamber containing loose connective tissue, blood vessels, and nerves.
# '''[[Cementum]]''': A bone-like mineralized tissue covering the root surface, providing attachment for the [[periodontal ligament]].

==Types of Teeth==
Humans are '''[[diphyodont]]''', meaning they develop two sets of teeth during their lifetime:

===Primary Dentition (Baby Teeth)===
* **Count**: 20 teeth.
* **Composition**: 8 [[incisors]], 4 [[canines]], 8 [[molars]].
* **Eruption**: Typically begins at 6 months and is complete by age 3.

===Permanent Dentition (Adult Teeth)===
* **Count**: 32 teeth (including third molars).
* **Composition**: 8 incisors, 4 canines, 8 [[premolars]], 12 molars.
* **Eruption**: Typically begins at age 6 and concludes in late adolescence.

==Dental Notation Systems==
To uniquely identify each tooth, clinicians use standardized systems:
* '''[[Universal Numbering System]]''': Primarily used in the United States (1–32).
* '''[[FDI World Dental Federation notation]]''': International standard using a two-digit quadrant-based system (e.g., 11, 21, 31, 41).
* '''[[Palmer notation method]]''': Uses a symbol ($┘, └, ┐, ┌$) representing the quadrant and a number.

==Clinical Significance==
* '''[[Dental caries]]''': The demineralization of tooth structure by bacterial acids.
* '''[[Bruxism]]''': Excessive grinding or clenching that leads to tooth wear ([[attrition]]).
* '''[[Endodontic therapy]]''': Treatment required when the dental pulp becomes infected or necrotic.
* '''[[Impacted tooth]]''': A tooth that fails to erupt fully into the oral cavity (common with [[wisdom teeth]]).

| Artery = [[Maxillary artery]], [[Facial artery]], [[Lingual artery]]
| Nerve = [[Trigeminal nerve]] (CN V), [[Facial nerve]] (CN VII), [[Glossopharyngeal nerve]] (CN IX)
}}

==Definition==
The '''oral cavity''', commonly referred to as the '''mouth''', is the first portion of the [[digestive system]]. It is bounded by the [[lips]] anteriorly, the [[cheeks]] laterally, the [[palate]] superiorly, and the [[floor of the mouth]] inferiorly. It communicates posteriorly with the [[oropharynx]] through the [[isthmus of fauces]].

==Anatomical Divisions==
The oral cavity is divided into two major parts by the [[alveolar process|alveolar arches]] (teeth and gums):

===1. Oral Vestibule===
The '''vestibule''' is the slit-like space between the inner surface of the lips and cheeks and the outer surface (facial/buccal) of the teeth and gingiva.
* The '''[[parotid duct]]''' (Stensen's duct) opens into the vestibule opposite the maxillary second molar.
* It is lined by non-keratinized [[stratified squamous epithelium]].

===2. Oral Cavity Proper===
The '''oral cavity proper''' is the space internal to the dental arches.
* '''Roof''': Formed by the [[hard palate]] (anterior two-thirds) and the [[soft palate]] (posterior third).
* '''Floor''': Occupied primarily by the [[tongue]] and supported by the [[mylohyoid muscle]].
* '''Lateral/Anterior boundaries''': The lingual surfaces of the teeth and [[gingiva]].

==Major Structures==

===The Tongue===
A muscular organ vital for [[mastication]], [[deglutition]] (swallowing), and [[speech]]. It is covered in [[papillae]], some of which contain '''[[taste buds]]'''.

===The Palate===
* '''[[Hard Palate]]''': A bony structure formed by the [[palatine process]] of the maxilla and the horizontal plate of the palatine bone.
* '''[[Soft Palate]]''': A muscular flap that closes the [[nasopharynx]] during swallowing. The '''[[uvula]]''' hangs from its posterior margin.

===Salivary Glands===
While the major glands ([[parotid gland|parotid]], [[submandibular gland|submandibular]], and [[sublingual gland|sublingual]]) are located outside the cavity walls, their ducts open into it. Hundreds of '''[[minor salivary glands]]''' are located within the oral mucosa.

==Clinical Significance==
* '''[[Oral Cancer]] Screening''': Most malignancies occur on the lateral borders of the tongue and the floor of the mouth.
* '''[[Xerostomia]]''': Subjective feeling of dry mouth, often caused by salivary gland hypofunction.
* '''[[Stomatitis]]''': Inflammation of the mucous membrane of the mouth.

==Definition==
'''Dentistry''', also known as '''Dental and Oral Medicine''', is the branch of [[medicine]] focused on the study, diagnosis, prevention, and treatment of diseases, disorders, and conditions of the [[oral cavity]], particularly the [[teeth]], [[oral mucosa]], and adjacent structures such as the [[maxilla]], [[mandible]], and [[salivary glands]].

While primarily associated with teeth among the general public, the field of dentistry or [[stomatology]] encompasses the entire craniofacial complex, including the [[temporomandibular joint]] (TMJ) and supporting muscular and nervous structures.

==History==
Evidence of dental surgery dates back to the [[Indus Valley Civilization]] (c. 7000 BC). Modern dentistry began to take shape in the 18th century, notably with the work of '''[[Pierre Fauchard]]''', known as the "Father of Modern Dentistry," who published ''Le Chirurgien Dentiste'' in 1728.

==Professional Education==
To practice dentistry, a practitioner must typically earn a professional degree:
* '''[[Doctor of Dental Surgery]] (DDS)'''
* '''[[Doctor of Medicine in Dentistry]] (DMD)'''
* '''[[Bachelor of Dental Surgery]] (BDS)''' (Common in Commonwealth nations)

Continuing Dental Education (CDE) is mandatory in most jurisdictions to maintain licensure and keep pace with technological advancements like '''[[Digital Dentistry]]'''.

==Specialties==
Most countries recognize several formal dental specialties that require additional residency training (usually 2–6 years):
* '''[[Dental Public Health]]''': Improving oral health on a population level.
* '''[[Endodontics]]''': Diagnosis and treatment of the [[dental pulp]] and periapical tissues.
* '''[[Oral and Maxillofacial Pathology]]''': The study of oral diseases (See [[Category:Oral Pathology]]).
* '''[[Oral and Maxillofacial Radiology]]''': Interpretation of [[X-ray]], [[CT]], and [[MRI]] data.
* '''[[Oral and Maxillofacial Surgery]]''': Surgical treatment of injuries and defects.
* '''[[Orthodontics]] and Dentofacial Orthopedics''': Alignment of teeth and jaws.
* '''[[Pediatric Dentistry]]''': Dental care for children and adolescents.
* '''[[Periodontology]]''': Treatment of the supporting structures of teeth (See [[Category:Periodontology]]).
* '''[[Prosthodontics]]''': Restoration of missing teeth with [[dentures]], [[bridges]], or [[implants]].

==Clinical Procedures==
Modern dental practice utilizes a variety of interventions:
* '''[[Preventive Dentistry]]''': [[Scaling and root planing]], [[fluoride therapy]], and patient education.
* '''[[Restorative Dentistry]]''': Fillings (see [[Dental composite resin]]), [[crowns]], and inlays.
* '''[[Endodontic Therapy]]''': Commonly known as a [[root canal]].
* '''[[Oral Surgery]]''': Tooth extractions and [[Guided Bone Regeneration]].

| Caption = Dental plaque made visible using a pink [[disclosing agent]].
| Symptoms = Fuzzy feeling on teeth, [[halitosis]], [[gingivitis]]
| Prevention = [[Toothbrushing]], [[flossing]], professional [[dental prophylaxis]]
}}

==Definition==
'''Dental plaque''' is a complex, organized '''[[biofilm]]''' that forms naturally on the surfaces of teeth and other hard structures in the mouth (such as [[dental implants]] and [[dentures]]). It consists of a diverse community of [[microorganisms]] embedded in a self-produced matrix of extracellular polymeric substances (EPS).

Unlike a simple food debris or "materia alba," dental plaque cannot be removed by rinsing with water; it requires mechanical disruption through oral hygiene practices.

==Composition==
* '''Microorganisms (70-80%)''': Primarily [[bacteria]], with over 700 species potentially present.
* '''Intercellular Matrix (20-30%)''': A "scaffold" composed of:
** '''[[Polysaccharides]]''' (e.g., glucans and fructans produced by ''[[Streptococcus mutans]]'').
** '''Proteins''' (derived from [[saliva]] and bacterial products).
** '''Lipids''' and '''DNA'''.
** '''Inorganic components''': Mainly [[calcium]] and [[phosphorus]].

==Formation Stages==
The development of dental plaque is a dynamic process occurring in four distinct phases:

# '''Acquired Pellicle Formation''': Within minutes of cleaning, a thin layer of salivary [[glycoproteins]] deposits on the [[enamel]].
# '''Initial Colonization''': Gram-positive facultative cocci (e.g., ''Streptococcus sanguinis'') bind to the pellicle via specific adhesins.
# '''Secondary Colonization (Co-aggregation)''': Filamentous bacteria like ''Actinomyces'' and "bridge" organisms like ''[[Fusobacterium nucleatum]]'' allow late-colonizing anaerobes to attach.
# '''Maturation''': The biofilm develops a 3D architecture with nutrient channels and reaches a state of '''[[homeostasis]]'''.

==Classification==
Dental plaque is clinically categorized by its location relative to the [[gingival margin]]:

===Supragingival Plaque===
Located above the gum line. It is predominantly aerobic and, if rich in saccharolytic bacteria, leads to the development of '''[[dental caries]]'''.

===Subgingival Plaque===
Located below the gum line within the [[gingival sulcus]]. It is dominated by anaerobic, proteolytic bacteria (the "[[Red Complex]]") which drive '''[[periodontitis]]'''.

==Pathological Potential==
If plaque is not disrupted, the microbial community undergoes '''[[dysbiosis]]'''.
* '''Acidogenesis''': Bacteria ferment dietary sugars into lactic acid, causing [[demineralization]] of enamel.
* '''Calculus Formation''': Over time, plaque can mineralize into '''[[dental calculus]]''' (tartar), which provides a rough surface for further plaque accumulation.
* '''Inflammation''': Microbial toxins trigger an immune response in the [[periodontium]].

==Introduction==
'''Oral microorganisms''', collectively known as the '''[[oral microbiome]]''' or oral microflora, refers to the complex community of [[bacteria]], [[archaea]], [[fungi]], [[protozoa]], and [[viruses]] that inhabit the human oral cavity. The mouth is one of the most colonized parts of the body, containing over 700 established species of bacteria.

While many of these organisms are commensal (harmless), an imbalance in the community—known as '''[[dysbiosis]]'''—is the primary driver of the two most common dental diseases: [[dental caries]] and [[periodontal disease]].

==The Oral Ecosystem==
The oral cavity provides various distinct habitats for microbial colonization:
* '''Hard surfaces''': Supragingival and subgingival tooth surfaces.
* '''Soft tissues''': The [[buccal mucosa]], tongue, and [[gingival sulcus]].
* '''Saliva''': Acts as a transport medium and nutrient source, though it also contains antimicrobial proteins like [[lysozyme]] and [[IgA]].

==Key Bacterial Taxa==
Bacteria are the most studied component of the oral microbiota. They are generally categorized by their role in health and disease.

===Gram-Positive Cocci (Early Colonizers)===
* '''[[Streptococcus mutans]]''': The primary pathogen associated with [[dental caries]] due to its ability to produce acid ([[acidogenicity]]) and survive in low pH environments ([[aciduricity]]).
* '''[[Streptococcus sanguinis]]''': Typically associated with oral health; it competes with ''S. mutans'' for space.

===Gram-Negative Anaerobes (Periodontal Pathogens)===
Commonly referred to as the "Red Complex" (as defined by Socransky et al.), these are highly associated with severe [[periodontitis]]:
# '''[[Porphyromonas gingivalis]]''': A "keystone pathogen" that subverts the immune response.
# '''[[Tannerella forsythia]]'''
# '''[[Treponema denticola]]'''

==Biofilm Formation==
Microorganisms in the mouth do not exist in isolation but form a complex '''[[dental plaque|biofilm]]'''. The process occurs in stages:
# '''Pellicle Formation''': Salivary proteins adhere to the enamel.
# '''Initial Adhesion''': Pioneer species (e.g., ''Streptococcus'' and ''Actinomyces'') bind to the pellicle.
# '''Co-aggregation''': Secondary colonizers (e.g., ''Fusobacterium nucleatum'') act as a bridge between early and late colonizers.
# '''Maturation''': The biofilm develops a complex 3D structure with water channels for nutrient transport.

==Clinical Implications==
* '''Caries''': Driven by acid-producing bacteria fermenting dietary carbohydrates.
* '''Endodontic Infections''': Usually polymicrobial, dominated by obligate anaerobes within the [[root canal]] system.
* '''Systemic Link''': Oral microorganisms can enter the bloodstream ([[bacteremia]]) and are linked to conditions like [[infective endocarditis]], diabetes, and cardiovascular disease.

| Image = [File:Anatomy_of_the_periodontium.jpg]
| Caption = The four main components of the periodontium supporting a tooth.
| System = [[Digestive system]]
| Latin = Periodontium
}}

==Definition==
The '''periodontium''' is the specialized biological system of tissues that both surround and support the [[teeth]], maintaining them in the [[maxilla]] and [[mandible]]. The word is derived from the Greek prefix ''peri-'' ("around") and ''-odont'' ("tooth").

Physiologically, the periodontium serves to attach the tooth to the bone tissue of the jaws and to act as a shock absorber during [[mastication]].

==Components==
The periodontium is composed of four main tissues. Two are mineralized (hard) and two are fibrous (soft):

===1. Gingiva (Gums)===
The '''[[gingiva]]''' is the epithelial and connective tissue that covers the [[alveolar process]] and surrounds the neck of the teeth. It provides a biological seal that protects the underlying structures from bacterial invasion.
* '''Free gingiva''': The unattached portion surrounding the tooth.
* '''Attached gingiva''': Firmly bound to the underlying alveolar bone.

===2. Periodontal Ligament (PDL)===
The '''[[periodontal ligament]]''' is a dense connective tissue organized into fiber bundles (primarily [[Type I collagen]]) that connect the [[cementum]] of the tooth to the alveolar bone.
* It transforms the pressure of biting into tension on the bone.
* It contains sensory receptors for proprioception (detecting tooth position and pressure).

===3. Cementum===
'''[[Cementum]]''' is a thin, mineralized layer of tissue covering the tooth root. Its primary function is to provide a medium for the attachment of the PDL fibers to the tooth. It is softer than [[dentin]] and [[enamel]].

===4. Alveolar Bone===
The '''[[alveolar process]]''' is the part of the jawbone that contains the tooth sockets ([[dental alveoli]]). It undergoes constant [[remodeling]] in response to mechanical forces and tooth movement.

==Clinical Significance==
The health of the periodontium is the primary focus of the dental specialty known as '''[[Periodontology]]'''.
* '''[[Gingivitis]]''': Inflammation confined to the gingiva.
* '''[[Periodontitis]]''': An inflammatory disease that leads to the destruction of the PDL and alveolar bone, potentially resulting in tooth loss.
* '''[[Periodontal pocket]]''': Pathological deepening of the gingival sulcus.

==Biological Width==
In [[restorative dentistry]], the '''[[biological width]]''' (or supracrestal attached tissues) refers to the combined height of the connective tissue attachment and the junctional epithelium. Maintaining this width is crucial for the health of the periodontium when placing [[crowns]] or [[fillings]].

Dentalwiki:

{{Infobox disease
| Name = Periodontitis
| Image =

[Image of stages of periodontal disease]

| Caption = Progression from healthy gums to advanced periodontitis.
}}

==Definition==
'''Periodontitis''' is a set of inflammatory diseases affecting the [[periodontium]]—the tissues that surround and support the teeth. It involves progressive loss of the alveolar bone around the teeth, and if left untreated, can lead to the loosening and subsequent loss of teeth.

==Pathogenesis==
Periodontitis is caused by [[microorganisms]] that adhere to and grow on the tooth's surfaces (notably '''[[dental plaque]]''' or biofilm), along with an overly aggressive immune response against these microorganisms.

===Stages===
# '''Gingivitis''': The precursor to periodontitis, characterized by inflammation of the gums without bone loss.
# '''Slight Periodontitis''': Early bone loss and pocket depth of 3–4 mm.
# '''Moderate Periodontitis''': Increased bone loss and pocket depth of 5–7 mm.
# '''Advanced Periodontitis''': Severe bone loss, tooth mobility, and pocket depths exceeding 7 mm.

==Treatment==
* '''Non-surgical''': Scaling and root planing (SRP) to remove biofilm and [[calculus]].
* '''Surgical''': Flap surgery, bone grafts, and guided tissue regeneration (GTR).

== Definition ==
'''Endodontics''' is the branch of [[Dentistry]] concerned with the morphology, physiology, and pathology of the human dental pulp and periradicular tissues. Its study and practice encompass the basic and clinical sciences including the biology of the normal pulp and the etiology, diagnosis, prevention, and treatment of diseases and injuries of the pulp and associated periradicular conditions.

== Anatomy of the Internal Tooth ==
The internal structure of the tooth is divided into:
* '''Pulp Chamber:''' The central portion in the crown of the tooth.
* '''Root Canals:''' The extensions of the pulp that run the length of the root to the apical foramen (the opening at the tip).
* '''[[Dental Pulp]]:''' A specialized loose connective tissue containing the neurovascular bundle.

== Common Procedures ==
=== Root Canal Therapy (RCT) ===
The most common endodontic procedure, involving the removal of diseased pulp tissue.
# '''Anesthesia and Isolation:''' Use of a [[Rubber dam]] is mandatory to maintain a sterile field.
# '''Cleaning and Shaping:''' Utilizing hand files or [[Nickel-Titanium (NiTi) Alloys|NiTi rotary files]] to remove bacteria and debris.
# '''Disinfection:''' Chemical irrigation with antimicrobial solutions.
# '''Obturation:''' Three-dimensional sealing of the canal system, typically with '''Gutta-percha'''.

=== Endodontic Microsurgery ===
When conventional RCT fails or cannot be performed, an '''Apicoectomy''' may be necessary. This involves the surgical removal of the root tip and a retrograde filling of the canal.

=== Vital Pulp Therapy ===
Procedures such as '''Pulpotomy''' or '''Pulp Capping''' aimed at preserving the vitality of the pulp, frequently performed in pediatric patients with immature permanent teeth.

== Technological Innovations ==
* '''[[CBCT]] Imaging:''' Allows for the detection of extra canals (e.g., MB2 in maxillary molars) and periapical lesions in 3D.
* '''Ultrasonics:''' Used for removing calcifications, posts, and activating irrigants for better cleaning.
* '''Bioceramic Sealers:''' Highly biocompatible materials that expand slightly upon setting to provide an exceptional seal.

== Clinical Success and Prognosis ==
Endodontic treatment has a high success rate (often >90%). Factors affecting prognosis include:
* The presence of a pre-operative periapical lesion.
* The quality of the final coronal restoration (Crown).
* The complexity of the root canal anatomy.

== Definition ==
'''Dental Biomaterials''' is a multidisciplinary field that combines [[Materials Science]] with clinical dentistry. These materials are engineered to replace missing tooth structure or supporting tissues while maintaining a harmonious relationship with the biological environment of the oral cavity.

== Classification by Material Type ==

=== 1. Dental Ceramics ===
Ceramics are inorganic, non-metallic solids. They are favored for their excellent aesthetics and biocompatibility.
* '''[[Zirconia]]:''' Often called "ceramic steel" due to its high fracture toughness. Used for crowns and implant abutments.
* '''Glass-Ceramics:''' Such as Lithium Disilicate (E.max), which provides superior translucency for anterior restorations.

=== 2. Metallic Materials ===
Metals are used primarily for their strength and ductility.
* '''[[Titanium]]:''' The gold standard for [[Dental Implants]] due to its ability to undergo [[Osseointegration]].
* '''Noble Alloys:''' Gold, Platinum, and Palladium alloys remain the most durable materials for posterior restorations (inlays/onlays).

=== 3. Polymeric Materials ===
Polymers are long-chain molecules used in various dental applications:
* '''Acrylic Resins:''' Used for the base of removable dentures.
* '''Thermoplastics:''' Used for the production of [[Orthodontic Aligners]].

=== 4. Composite Resins ===
A "composite" combines two or more different materials to achieve properties that neither could achieve alone.
* '''Matrix:''' Usually a resin like Bis-GMA.
* '''Filler:''' Glass or silica particles that provide strength and reduce shrinkage.
* '''Coupling Agent:''' Silane, which bonds the filler to the matrix.

== Biological Requirements ==
For a material to be considered a "biomaterial" in dentistry, it must pass several safety tests:
# '''Acute Toxicity:''' Must not release harmful substances.
# '''Hypersensitivity:''' Must have a low potential for causing allergic reactions (e.g., concerns regarding Nickel).
# '''Pulp Compatibility:''' Materials used in deep cavities must not irritate the dental pulp.

== Future Trends: Bioactive Materials ==
The next generation of biomaterials is shifting from "passive" (inert) to "active."
* '''Remineralizing Materials:''' Releasing fluoride, calcium, or phosphate ions to heal early [[Dental Caries|caries]].
* '''Scaffold Materials:''' Used in tissue engineering to regrow pulp or bone.

{{Short description|Shape-memory alloys used in orthodontics and endodontics}}
__TOC__

== Definition ==
'''Nickel-Titanium (NiTi)''' alloys, commonly known as '''Nitinol''' (Nickel Titanium Naval Ordnance Laboratory), are a class of [[Dental Biomaterials|biomaterials]] that exhibit unique mechanical properties: superelasticity and shape memory. They typically consist of approximately 55% Nickel and 45% Titanium.

== Phase Transformations ==
The mechanical behavior of NiTi is governed by the transformation between two crystalline lattice structures:
* '''Austenite:''' The rigid, "high-temperature" phase. In this state, the wire "remembers" its manufactured shape.
* '''Martensite:''' The flexible, "low-temperature" phase. The metal is easily deformed in this state, allowing it to be engaged into crowded teeth or curved canals.

=== The Stress-Strain Relationship ===
Unlike stainless steel, which follows a linear elastic relationship, NiTi exhibits a '''Stress Plateau'''. This means that as the wire is deactivated (the tooth moves), the force delivered remains nearly constant over a large range of movement, which is biologically ideal for bone remodeling.

== Applications in Dentistry ==

=== Orthodontic Archwires ===
NiTi archwires are used in the initial stages of treatment to:
* Align crowded teeth with minimal patient discomfort.
* Provide constant force that reduces the risk of [[Root Resorption]].
* '''Copper-NiTi (Cu-NiTi):''' A variant that adds copper to the alloy to make the transformation temperature more precise (often triggered by the heat of the patient's mouth).

=== Endodontic Rotary Files ===
The introduction of NiTi transformed [[Endodontics]] by allowing for:
* '''Increased Flexibility:''' Files can follow the natural curvature of the root canal.
* '''Reduced Procedure Time:''' Transition from manual hand-filing to mechanized rotary systems.
* '''Cyclic Fatigue Resistance:''' Modern heat-treated (Gold or Blue) NiTi files are highly resistant to breaking inside the canal.

== Clinical Precautions ==
* '''Nickel Allergy:''' While the $TiO_2$ layer provides protection, patients with a severe nickel hypersensitivity should be treated with alternative materials like Titanium-Molybdenum Alloy (TMA) or Stainless Steel.
* '''Sterilization:''' Repeated autoclaving can alter the transformation temperatures of certain NiTi alloys, potentially affecting their clinical performance.

__TOC__

== Our Identity ==
'''Dental.wiki''' is an independent, community-driven platform designed to be the comprehensive digital reference for the dental profession. In an era where [[Digital Dentistry]] and [[Dental Technology]] are evolving at an unprecedented pace, we provide a stable, verified, and structured environment for knowledge exchange.

== The Vision ==
Our vision is to democratize high-level dental education. We believe that a dentist in a remote clinic should have access to the same evidence-based protocols as a specialist at a major university. By centralizing our collective knowledge, we reduce the "information silo" effect in the dental industry.

== Key Pillars of the Project ==

=== 1. Evidence-Based Dentistry (EBD) ===
Every clinical entry on Dental.wiki is encouraged to cite high-level evidence, including:
* Systematic Reviews and Meta-analyses.
* Randomized Controlled Trials (RCTs).
* Clinical Practice Guidelines from recognized international dental associations.

=== 2. Technological Integration ===
We focus heavily on the intersection of biology and technology. This includes dedicated sections for:
* [[CAD/CAM]] workflows.
* [[Artificial Intelligence in Dentistry]].
* Novel [[Dental Biomaterials]].

=== 3. Global Collaboration ===
Dental.wiki is a multilingual project. We aim to break down language barriers in dental research, allowing for the translation of complex surgical and restorative protocols into multiple languages to serve a global patient base.

== Editorial Standards ==
To maintain the integrity of our content, Dental.wiki follows three strict rules:
# '''Verifiability:''' Information must be supported by reliable, third-party sources.
# '''Non-Commercialism:''' Articles should describe technologies (e.g., "Intraoral Scanners") rather than serve as advertisements for specific brands.
# '''Professionalism:''' Content is written for a professional audience, utilizing correct anatomical and clinical terminology.

== How to Help ==
As a community-based project, we rely on your expertise. You can help by:
* Creating new pages for emerging dental topics.
* Updating existing articles with the latest research findings.
* Donating high-quality clinical photographs or [[CBCT]] scans to our media library.

== Contact and Support ==
Dental.wiki is managed by a global team of dental educators and technologists.

__TOC__

== Definition ==
'''Cephalometric Analysis''' is a diagnostic procedure in [[Orthodontics]] that involves the measurement and interpretation of a lateral head radiograph (Cephalogram). It is used to analyze dental and skeletal relationships to determine the nature of a [[Malocclusion]] and to plan surgical or orthodontic treatment.

== Landmarks and Planes ==
The analysis relies on identifying specific points (landmarks) on the radiograph:

=== Skeletal Landmarks ===
* '''Sella (S):''' Midpoint of the sella turcica.
* '''Nasion (N):''' The most anterior point of the suture between the frontal and nasal bones.
* '''A-Point:''' The deepest point on the curve of the maxilla between the anterior nasal spine and the dental arch.
* '''B-Point:''' The deepest point on the curve of the mandible.
* '''Menton (Me):''' The lowest point of the chin.

=== Reference Planes ===
* '''SN Plane:''' Represents the anterior cranial base.
* '''Frankfort Horizontal (FH):''' A line connecting the upper border of the external auditory meatus (Porion) and the lower border of the orbital rim (Orbitale).
* '''Mandibular Plane:''' A line representing the lower border of the mandible.

== Clinical Interpretations ==
The measurements derived from these landmarks help classify the patient's skeletal profile:

{| class="wikitable"
! Measurement !! Normative Value !! Interpretation
|-
| '''SNA Angle''' || 82° ± 2° || Position of the Maxilla relative to the skull.
|-
| '''SNB Angle''' || 80° ± 2° || Position of the Mandible relative to the skull.
|-
| '''ANB Angle''' || 2° || 0-4° = Class I; >4° = Class II; <0° = Class III skeletal relationship.
|-
| '''IMPA''' || 90° || The inclination of the lower incisor relative to the mandibular plane.
|}

== Digital Cephalometry ==
With the rise of [[Digital Dentistry]], manual tracing of radiographs on acetate paper has been largely replaced by software (e.g., Dolphin Imaging, CephX). Modern systems utilize [[Artificial Intelligence]] to automatically detect landmarks, increasing speed and reducing inter-operator variability.

== Applications ==
* '''Treatment Planning:''' Deciding whether a case requires extraction, surgery, or simple alignment.
* '''Growth Prediction:''' Assessing the remaining growth potential in adolescent patients.
* '''Research:''' Studying the long-term effects of orthodontic mechanics on the facial profile.

__TOC__

== Definition ==
'''Fixed Appliances''' are orthodontic systems where the components are bonded or cemented to the teeth and cannot be removed by the patient. They are used to treat a wide variety of [[Malocclusion|malocclusions]] by applying precise, continuous forces to achieve three-dimensional control over tooth position.

== Components ==
A standard fixed appliance setup (often called "braces") consists of:
* '''Brackets:''' Metal or ceramic attachments bonded to the facial or lingual surface of the teeth.
* '''Archwires:''' The "engine" of the appliance. Initial wires are usually flexible [[Nickel-Titanium]] (NiTi), while finishing wires are often rigid stainless steel.
* '''Ligatures:''' Elastic "modules" or wire ties that secure the archwire into the bracket slot. '''Self-ligating brackets''' use a built-in "trap door" to hold the wire without elastics.
* '''Molar Bands/Tubes:''' Anchors placed on the posterior teeth to stabilize the archwire.
* '''Elastics:''' Removable rubber bands used to coordinate the upper and lower arches (Class II or Class III correction).

== Types of Fixed Appliances ==
=== Metal Braces ===
The most common type, made of high-grade stainless steel. They are durable, cost-effective, and offer the least friction during tooth movement.

=== Ceramic (Aesthetic) Braces ===
Made of polycrystalline or monocrystalline alumina. They mimic the color of natural enamel, making them popular with adult patients, though they are more brittle and can cause wear on opposing teeth.

=== Lingual Braces ===
Brackets are bonded to the ''inside'' (tongue side) of the teeth. This makes them completely invisible from the front but can affect speech and tongue comfort initially.

=== Self-Ligating Brackets ===
Systems like the '''Damon System''' or '''SmartClip''' eliminate the need for elastic ligatures. This is claimed to reduce friction and potentially shorten treatment time in specific cases.

== Clinical Advantages ==
* '''Predictability:''' Excellent for complex movements like tooth translation (moving the whole tooth, root included) and severe rotations.
* '''Compliance-Free:''' Since they are fixed, the treatment progresses 24/7 without the patient needing to remember to "wear" them.
* '''Versatility:''' Can be used in conjunction with [[Temporary Anchorage Devices]] (TADs) for extreme skeletal corrections.

== Maintenance and Risks ==
* '''Oral Hygiene:''' Fixed appliances act as plaque traps. Poor hygiene can lead to "white spot lesions" (decalcification) or [[Gingivitis]].
* '''Root Resorption:''' Excessive or prolonged force can lead to the shortening of tooth roots.
* '''Soft Tissue Irritation:''' Brackets may cause initial ulceration of the cheeks or lips, usually managed with orthodontic wax.

{{Short description|Specialty focused on tooth alignment and jaw correction}}
__TOC__

== Definition ==
'''Orthodontics''' (from Greek ''orthos'' "straight" and ''odont'' "tooth") is the first specialty created in dentistry. It focuses on the alignment of teeth and the dental arches (the maxilla and the mandible) to improve both function (chewing and speech) and facial aesthetics.

== The Biology of Tooth Movement ==
Orthodontic treatment relies on the physiological process of '''Bone Remodeling'''.
* '''Periodontal Ligament (PDL):''' The sensory tissue that mediates the force between the tooth and the bone.
* '''Osteoclasts:''' Cells that break down bone on the side where the tooth is being pushed.
* '''Osteoblasts:''' Cells that build new bone on the side where the tooth is being pulled.
''Optimal force must be light and continuous to prevent root resorption.''

== Angle's Classification of Malocclusion ==
In 1899, [[Edward Angle]] classified the relationship of the teeth into three main groups:
* '''Class I:''' The "ideal" bite where the mesiobuccal cusp of the upper first molar aligns with the buccal groove of the lower first molar.
* '''Class II:''' Often characterized by a receding lower jaw or protruding upper teeth (overjet).
* '''Class III:''' Characterized by a prominent lower jaw or a "crossbite" where lower teeth are in front of upper teeth.

== Orthodontic Appliances ==
=== Fixed Braces ===
The most common method, involving:
* '''Brackets:''' Bonded to the tooth using [[Adhesive Dentistry]] techniques.
* '''Archwires:''' The engine of the movement; often made of Nickel-Titanium (NiTi) for its "shape memory" properties.

=== Clear Aligner Therapy (CAT) ===
A modern alternative to braces, such as [[Orthodontic Aligners]]. They offer superior aesthetics and oral hygiene but require high patient compliance (22 hours/day wear).

=== Orthopedic Appliances ===
Used primarily in growing children to modify jaw growth (e.g., Twin Block, Headgear, or Rapid Palatal Expanders).

== Retention Phase ==
After active treatment, teeth have a natural tendency to return to their original positions (relapse). '''Retainers''' are mandatory to allow the bone and ligaments to stabilize:
* '''Fixed Retainers:''' A wire bonded to the back of the teeth.
* '''Removable Retainers:''' Clear Essix-style trays or Hawley retainers.

{{Short description|Management of diseased teeth and functional rehabilitation}}
__TOC__

== Definition ==
'''Restorative Dentistry''' involves the restoration of natural teeth that have been damaged by [[Dental Caries|decay]], trauma, or erosion, as well as the replacement of missing teeth. The primary goal is to return the mouth to full function (mastication) while maintaining an aesthetic appearance.

== Types of Restorations ==

=== Direct Restorations ===
These are performed in a single clinical appointment.
* '''[[Dental Composite|Composite Resin]]:''' Tooth-colored material that provides excellent aesthetics and allows for conservative tooth preparation through [[Adhesive Dentistry]].
* '''[[Glass Ionomer Cement]] (GIC):''' Often used in pediatric dentistry or as a base, known for releasing fluoride to prevent secondary decay.
* '''Amalgam:''' A mixture of metals (silver, mercury, tin, copper). While decreasing in popularity due to aesthetics and environmental concerns, it is highly durable for posterior teeth.

=== Indirect Restorations ===
These require at least two visits or the use of [[Digital Dentistry|In-office Milling]].
* '''[[Crown (dentistry)|Crowns]]:''' A "cap" that covers the entire tooth to provide strength when the remaining structure is compromised.
* '''[[Inlays and Onlays]]:''' Used when the damage is too great for a filling but not severe enough for a full crown.
* '''Veneers:''' Thin shells (porcelain or composite) bonded to the front of teeth, primarily for aesthetic enhancement.

== Principles of Tooth Preparation ==
The success of a restoration depends on specific engineering principles:
# '''Retention Form:''' Features that prevent the restoration from being pulled out vertically.
# '''Resistance Form:''' Features that prevent the restoration or the tooth from fracturing under occlusal (biting) forces.
# '''Structural Durability:''' Ensuring the material has enough thickness to withstand wear.
# '''Marginal Integrity:''' The "seal" at the edge of the restoration to prevent bacteria from entering.

== Materials in Restorative Dentistry ==
* '''Ceramics:''' E.max (Lithium Disilicate) and [[Zirconia]] are the current gold standards for indirect restorations.
* '''Resins:''' Light-cured polymers used for direct bonding.
* '''Metals:''' Gold alloys are still considered the most biocompatible and long-lasting material for posterior restorations, though less common today due to cost and aesthetics.

__TOC__

== Definition ==
'''Adhesive Dentistry''' refers to the procedures involved in joining dental materials to tooth structure (enamel and dentin) through chemical and micromechanical forces. This approach allows for the preservation of healthy tooth structure, as it does not require the extensive "undercut" preparations needed for traditional materials like [[Amalgam]].

== Core Concepts ==

=== Enamel Bonding ===
Enamel bonding is achieved through '''Acid Etching''' (typically with 37% phosphoric acid). This process removes about 10 microns of the enamel surface and creates microporosities. When a low-viscosity resin (bonding agent) is applied, it flows into these pores, creating '''Resin Tags''' that provide a powerful mechanical bond.

=== Dentin Bonding and the Hybrid Layer ===
Bonding to dentin is challenging because dentin contains significant water and organic [[Collagen]].
* '''Hybrid Layer:''' Formed when the adhesive resin infiltrates the demineralized collagen network of the dentin.
* '''Smear Layer:''' A layer of debris created during tooth preparation that must be either removed or modified to achieve a successful bond.

== Bonding Strategies ==
Current adhesive systems are categorized by how they handle the tooth surface:
* '''Etch-and-Rinse (Total Etch):''' A separate phosphoric acid step is used to etch both enamel and dentin. It provides the strongest bond to enamel but can lead to post-operative sensitivity if the dentin is over-dried.
* '''Self-Etch:''' Uses acidic primers that etch and prime simultaneously. This creates a thinner hybrid layer but significantly reduces sensitivity by not fully exposing the dentinal tubules.
* '''Universal Adhesives:''' Multimode systems that allow the clinician to choose the etching strategy based on the specific clinical situation.

== Clinical Applications ==
Adhesive dentistry is the foundation for:
* [[Dental Composite|Composite Resins]] (Fillings)
* [[Veneer (dentistry)|Dental Veneers]]
* [[Inlays and Onlays]]
* Bonded [[Dental Bridges]] (Maryland Bridges)

== Factors Affecting Bond Strength ==
* '''Moisture Control:''' Contamination by saliva or blood is the leading cause of bond failure. The use of a [[Rubber dam]] is highly recommended.
* '''Curing Light Intensity:''' Proper polymerization of the resin is critical for long-term stability.
* '''Material Compatibility:''' Ensuring the adhesive is compatible with the restorative resin or cement.

{{Short description|Surgical component to support dental prostheses}}
__TOC__

== Definition ==
A '''Dental Implant''' (also known as an endosseous implant or fixture) is a surgical device used to replace missing teeth by providing a stable foundation for fixed or removable replacements. Unlike traditional bridges, implants do not require the alteration of adjacent teeth.

== Biological Principles ==
The fundamental principle of modern dental implants is '''[[Osseointegration]]'''.
* '''Discovery:''' Discovered by [[Per-Ingvar Brånemark]], who observed that bone would bond nearly permanently to titanium.
* '''Process:''' Following surgical placement, osteoblasts (bone-forming cells) grow directly onto the microscopic roughness of the implant surface.
* '''Stability:'''
** ''Primary Stability:'' The mechanical "grip" of the implant in the bone immediately after surgery.
** ''Secondary Stability:'' The biological bond formed through healing.

== Components ==
A complete implant restoration consists of:
# '''Implant Body:''' The portion that resides in the bone. Most are made of '''Grade 4 Titanium''' or '''Titanium Alloy (Ti-6Al-4V)'''.
# '''[[Abutment]]:''' The interface that connects the internal screw of the implant to the oral environment.
# '''Restoration:''' The [[Crown (dentistry)|Crown]], [[Bridge (dentistry)|Bridge]], or [[Denture]] that is either screwed or cemented to the abutment.

== Surgical Procedure ==
The treatment is typically divided into phases:
# '''Treatment Planning:''' Utilization of [[CBCT]] and digital scans to assess bone volume and vital structures.
# '''Implant Placement:''' A hole is prepared in the bone (osteotomy) using sequential drills under irrigation, and the implant is inserted.
# '''Healing (Stage I):''' A period of 3–6 months for osseointegration.
# '''Restoration (Stage II):''' Placement of the abutment and the final prosthetic.

== Clinical Indications ==
* '''Single Tooth Replacement:''' To restore a gap without "sacrificing" healthy neighboring teeth.
* '''Multiple Teeth Replacement:''' Supporting an implant-supported bridge.
* '''Full Arch Rehabilitation:''' Concepts such as '''All-on-4®''', where a full set of teeth is supported by four strategically placed implants.

== Contraindications and Risks ==
* '''Absolute:''' Recent myocardial infarction, active high-dose bisphosphonate therapy (IV), or uncontrolled systemic disease.
* '''Relative:''' Heavy smoking, uncontrolled diabetes, and bruxism.
* '''Failure:''' May occur due to infection ('''[[Peri-implantitis]]''') or lack of primary stability.

== Definition ==
'''Dentistry''' is the health care profession devoted to maintaining the health of the teeth, gums, and other tissues in and around the mouth. It is an integral part of general health, as oral diseases are often linked to systemic conditions such as diabetes and cardiovascular disease.

== History ==
* '''Ancient Origins:''' Evidence of tooth drilling for medicinal purposes dates back over 9,000 years.
* '''The Father of Modern Dentistry:''' [[Pierre Fauchard]] (1678–1761) revolutionized the field by introducing dental fillings as a treatment for caries.
* '''Modern Era:''' The 20th and 21st centuries saw the introduction of [[Fluoride]], [[High-speed handpieces]], and [[Digital Dentistry]].

== Dental Anatomy ==
Understanding the structures of the oral cavity is fundamental to the practice:
* '''Enamel:''' The hardest substance in the human body, protecting the crown.
* '''Dentin:''' The layer beneath enamel that makes up the bulk of the tooth.
* '''Pulp:''' The central part of the tooth containing nerves and blood vessels.
* '''Periodontium:''' The specialized tissues that surround and support the teeth (gingiva, alveolar bone, periodontal ligament).

== Specialized Branches ==
While general dentists handle routine care, complex cases are referred to specialists:
* [[Orthodontics]]: Focuses on malocclusions and dentofacial orthopedics.
* [[Endodontics]]: Specialized in the dental pulp and periradicular tissues.
* [[Periodontics]]: Focuses on the inflammatory diseases that destroy the gums and bone.
* [[Prosthodontics]]: Concerned with the prosthetic replacement of missing teeth.
* [[Pediatric Dentistry]]: Specialized care for infants and children through adolescence.
* [[Oral and Maxillofacial Surgery]]: Surgical treatment of diseases, injuries, and defects.

== Common Pathologies ==
* '''[[Dental Caries]]:''' Tooth decay caused by bacterial biofilm and sugar.
* '''[[Gingivitis]] and [[Periodontitis]]:''' Inflammatory diseases of the gums and bone.
* '''[[Bruxism]]:''' Involuntary grinding or clenching of teeth.
* '''[[Oral Cancer]]:''' Malignancies appearing in the oral cavity.

== Future of Dentistry ==
The field is currently transitioning toward:
* '''Regenerative Dentistry:''' Using stem cells to regrow tooth structures.
* '''[[Artificial Intelligence]]:''' Automated diagnostic tools for X-ray and 3D scan analysis.
* '''Minimal Intervention Dentistry:''' Focus on preserving as much natural tooth structure as possible.
