  Objective: The aim of this in vitro study was to incorporate two antioxidants namely sweet potato and grape seed extracts with 30% hydrogen peroxide and to evaluate its effect on the enamel surface and the bond strength of resin composite to enamel. Materials and Methods: Labial enamel surfaces of 90 extracted human maxillary central incisors were randomly divided into 6 groups of 15 each based on different bleaching protocols. Groups I and II were allotted to negative (no bleaching) and positive (bleaching with 30% hydrogen peroxide only) controls. The rest were the experimental groups; bleaching with 30% hydrogen peroxide incorporated with 2% sweet potato and 5% grape seed extracts (Groups III and IV respectively) and bleaching followed by application of sweet potato and grape seed extracts (Groups V and VI respectively). Following bleaching procedure, 5 specimens were evaluated for.. View More»
