Abstract

Direct composite veneer is often done to increase the aesthetics of teeth after bleaching. In direct composite veneer treatment, the presence of free radicals residual after bleaching can inhibit the polymerization of the bonding agent and decrease composite shear bond strength. Increasing shear bond strength of composite resin after bleaching can be done with the application of antioxidant agent. Guava is a fruit rich in antioxidant such as ascorbic acids, carotenoids and fenols. This study aims to evaluate the difference between the effectiveness of 10%, 20%, and 40% guava extract solution as natural antioxidants to improve the shear bond strength of direct composite veneer to bleached enamel. This cross-sectional study design divided 20 permanent premolar teeth into four groups: control group, 10%, 20%, and 40% guava extract solution group. Composite shear bond strength was measured with Universal Testing Machine. Data were analyzed using ANOVA followed by a Post Hoc test. The result showed shear bond strength of the four groups’ scores was 1.33 ± 0.42 MPa, 3.0 ± 1.06 MPa, 2.11 ± 0.61 MPa, and 1.94 ± 0.65 MPa, respectively. Significant highest shear bond strength values were observed in the 10% guava extract solution group (p < 0.05). 10% guava extract solution was the most effective natural antioxidant to improve the shear bond strength of direct composite veneer to bleached enamel.In conclusion, 10% guava extract solution was the most effective natural antioxidant to improve shear bond strength of direct composite veneer to bleached enamel. The significance of this study was to find alternative natural antioxidants applications after tooth bleaching.
