==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.
