Comparative Evaluation of Shear Bond Strength of Three Different Generations of Adhesive to Dentin: An In Vitro Study

Abstract

The clinical use of resin composites has expanded considerably over the past few years due to increased esthetic demands by patients, new improved formulations, and simplification of bonding procedures. Novel resin composites benefits from improved filler technology and modifications of the organic matrix for a greater degree of polymerization .Improved marginal sealing around composites has reduced the frequency of unfavorable postoperative responses. The sealing ability of a composite restoration is directly related to the effectiveness of the adhesive system used, as the lack of bonding and inadequate marginal sealing may lead to restoration failure.
