Dentin- and enamel-bonding agents

摘要: The introduction of bonding agents in restorative dentistry has made it possible to adhere materials tooth structure. Since bonded restorations were introduced by Buonocore 1955, extensive research been conducted develop systems that bond equally effectively enamel and dentin. Researchers have identified a micromechanical retention mechanism for the attachment hydrophobic resin both dentin works if appropriate conditioning or priming steps are applied. At site, modes action current adhesive converge create resin-dentin interdiffusion zone between deep structures filling material. To incorporate remove smear layer this zone, different adhesion strategies followed obtain bond. In clinical situation, these modern dentin-bonding more technique sensitive; thickness interface, its elastic capacity, polymerization efficiency initiation agent, and, finally, application used material play an important role final result.
