| Abstract | ||||
| Purpose: This study evaluated the effect of ascorbic acid on shear bond strength at tooth restoration interface after immediate bleaching procedures. Materials and Methods: Sixty freshly extracted human premolars were used. Teeth were divided into two main groups (A& B) according to the application mode of the adhesive system (n=30). Group A: self-etch mode, Group B: Etch-and-rinse mode. Each group was subdivided into three subgroups (1,2,3) according to ascorbic acid application (n=10). Data were collected, tabulated, and statistically evaluated. Results: The immediately bonded specimens after the bleaching procedure showed the statistically lowest mean shear bond strength values. These results were in comparison to the other unbleached specimens due to enamel surface energy. The antioxidant treatment exerted a significant effect on shear bond strength. Conclusion: Bleaching had a direct effect on enamel. Bond strength is adversely affected by bleaching. Ascorbic acid improves the bond of enamel after bleaching | ||||
