Background: Composite resins have disadvantages such as low hardness level, shrinkage, and micro-leakage. In the case of deep cavity restorations, bulk-fill composite resins have begun to be used because they facilitate the restoration work and make the restoration time shorter.
Purpose: This study was used to determine whether home bleaching treatment using hydrograph peroxide and carbamide peroxide can reduce the surface hardness of flowable bulk-fill composite resins.
Methods: The research sample is cylindrical with a diameter of 5 mm and a height of 2 mm, this study was divided into 3 groups. Then each group was measured by Vickers Hardness Tester.
Results: In the One Way Anova test the value of p = 0.020 was obtained. This indicates a significant difference in the surface hardness of bulk-fill flowable composite resins and a Post hoc test - Tukey HSD must be performed.
Conclusion: The results show that hydrogen peroxide home bleaching agent can significantly reduce the surface hardness of bulk-fill flowable composite resins
