Abstract

Background: Immediately after tooth whitening, the bond strength between the adhesive materials and enamel decreases, it is necessary to wait between 7 to 21 days for adhesive procedures. Objective: To evaluate the bonding resistance to enamel exposed to different antioxidants after whitening treatment with 35% hydrogen peroxide. Materials and methods: Bovine teeth were used. All the specimens received whitening treatment with 35% hydrogen peroxide, two applications of 15 minutes each were made, for two sessions every 7 days. After the treatment, the specimens were randomized to receive the different antioxidants for 10 minutes on the enamel. evaluating four groups: grape seed oil (ASU), 5% grape seed extract (ESU); negative control (bleaching without antioxidant) and positive control (without bleaching and without antioxidant). Subsequently, the restorative treatment with fluid resin was carried out. The micro shear test was used on the universal machine. The ANOVA test was used to compare the binding resistance values of the different groups evaluated, assuming normality. Results: It was found that the groups exposed to antioxidants presented the lowest values of binding resistance when compared with the group without bleaching, without significant differences between the fixed oil of ESU 8.09 (3.24) MPa and the seed extract grape 8.08 (3.79) MPa (p <0.05). Conclusions: The extract and essential oil of grape seed diminishes the resistance of bonding to the enamel after whitening treatment with hydrogen peroxide to 35%.
