The purpose of the study was to compare the effect of hydrogel and solution of sodium ascorbate on enamel-resin composite shear bond strength after bleaching. 40 buccal enamel surfaces of maxillary molar were taken, divided into 4 groups (n=10). Group I (bleaching with 10% carbamide peroxide), group 2 (bleaching and 10% sodium ascorbate solution), group 3 (bleaching + 10% sodium ascorbate hydrogel) and group 4 (bleaching + 20%) sodium ascorbate hydrogel). All the teeth were restored with composite and subjected to shear bond testing. The results were evaluated. The data was analyzed by ANOVA test and multiple comparisons by Post Hoc tests. It was concluded that there was increase in the bond strength when antioxidants were used after bleaching but there was no significant difference among the different forms of sodium ascorbate. |
