Development of Dentin Bonding Systems from Past to Present

Adhesive systems are one of the most important factors affecting the success of restorative dentistry. First, adhesive dentistry was born out of the idea of Buonocore (1) to provide retention with micromechanical retention by roughening the enamel tissue with 85% phosphoric acid for 30 seconds. At the end of the 1970s, dentin bonding systems have made a major breakthrough with the introduction of the view that phosphoric acid can be applied on dentin tissue.The mechanism of adhesion of the dentin bonding systems used today to the tissues of the teeth is defined as a natural micromechanical adhesion with the penetration of adhesive resin to collagen which is exposed on the surface of the dentin roughened with acid. “Hybrid Layer” (2) in other words’ interdiffusion layer’ (3) is one of the basic mechanisms of adhesion. The terms and their meanings used to understand adhesion mechanism are very important. Adhesion
