| Popis: | Introduction: If adhesive restorations are carried out immediately, the Shear Bond Strength (SBS) to bleached enamel is reduced. The use of antioxidants can be highlighted since it seems to be a more effective alternative to reduce or remove the residual oxygen and immediate improvement in SBS. Aim: The purpose of this in-vitro study was an attempt to regain the lost bond strength, for which, the comparison of SBS of composite resin to bleached enamel was carried out using various antioxidants i.e., 5% grape seed extract, 5% pine bark extract, 5% pomegranate peel extract. Materials and Methods: Labial enamel surfaces of 50 extracted human maxillary central incisors were randomly divided into 5 groups based on the antioxidant used as follows: Group I (n=10): Bleaching with 40% hydrogen peroxide gel for 10 minutes, without the use of an antioxidant; Group II (n=10): Bleaching followed by the use of 5% grape seed extract solution; Group III (n=10): Bleaching followed by the use of 5% pine bark extract solution Group IV (n=10): bleaching followed by the use of 5% pomegranate extract solution; and Group V (n=10): Control group in which no Bleaching was done. SBS of the specimens was tested using universal testing machine. The data were tabulated and statistically analyzed using computer software Statistical Package for Social Sciences (SPSS) version 16.0. One-way analysis of variance (ANOVA) followed by Mann Tukey Post hoc test. Results: Mean SBS values were compared in all the groups and there was a statistically significant difference present among the groups (p |
