Four generations of total-etch (fourth, fifth) and self-etching (sixth, seventh) bonding agents for use with resin composites are commercially available in the United States. The effect of desensitizing treatments on the bond strength of resin composite to dentin mediated by a self-etching primer. At the same time, bonding to tooth structure depends not only on adhesive systems but also on the bonding substrates. Thus, apart from its widely known antimicrobial property16 and it not significantly affecting bond strength to dentin, the use of chlorhexidine solution on acid-etched dentin may have the additional potential of preventing collagen fibril degradation in dentin hybrid layers. The use of amalgam restorations has steadily declined over the years, but composite resin placement has doubled or, at some ages, tripled from 1992-2007.

Definition of Dentin Bonding Agents: The dentine bonding agents are di or multi-functional organic molecules that contain reactive groups which interact with dentin and the monomer of the restorative resin [6, 7]. For proper bonding of resin composite restorations, dentin should be conditioned with polyacrylic acids to remove the smear layer, created during mechanical treatment with dental bore, and expose some of the collagen network or organic matrix of dentin.
