Editing Adhesive Dentistry (section)

== 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.
