| Abstract | ||||
| Objective: The study was conducted to assess the impact of Moringa Oleifera and ascorbic acid on microshear bond strength of composite resin to bleached Enamel. Methods: Twenty-five bovine incisors were divided into five groups of 5 teeth each; Group I : Where no bleaching was done and no antioxidants were used , Group II: Where bleaching was done, but no antioxidants were used, Group III (Positive control group): Bleaching followed by treatment with 10 % Ascorbic acid solution for 10 minutes, Group IV : Bleaching followed by treatment with 80 % ethanol extract of Moringa Oleifera for 10 minutes, Group V: Bleaching followed by treatment with 80 % methanol extract of Moringa Oleifera for 10 minutes. Resin composite was applied on enamel surfaces of all groups. The microshear bond strength were evaluated for all groups. Results: The results revealed statistically significant difference between the five groups where the highest mean value (17.34 Mpa) was recorded for (Group I; No bleaching) followed by (9.22 Mpa) was recorded for (Group III; Ascorbic Acid treatment after bleaching). The least mean value (4.41 Mpa) was recorded for (group II; No antioxidant after bleaching). No statistically significant difference was found between (Group III) and (Group IV). Conclusion: Using 10 % Ascorbic acid solution could reverse the reduced bond strength after bleaching and Ethanol extract of Moringa Oleifera can be a future candidate to be used as antioxidant solution after bleaching.
