dc.description.abstractBACKGROUND Nowadays, teeth whitening has become an important procedure in dental practice. According to results of previous studies, the bond strength values of bonded restorations are decreased when the teeth have been whitened with an office or home bleaching technique. The aim of this in-vitro study is to explore the effect of antioxidant implementation on enamel after whitening on the shear bond strength to enamel surface. METHODS The buccal enamel surfaces of 100 extracted teeth were divided non randomly into two groups for bonding with Single Bond [Group A] (3M ESPE) or Clearfil SE [Group B] (Kuraray). Each group was then divided into five random subgroups: 1. the negative control group (NC) received no whitening treatment [Group Al and Group B1]; 2. whitened with 15% carbamide peroxide and that received no antioxidant agents [Group A2 and Group B2]; 3. whitened with 15% carbamide peroxide and implemented 10% sodium ascorbate (SA) [Group A3 and Group B3]; 4. whitened with 35% hydrogen peroxide and that received no antioxidant agents [Group A4 and Group B4]; 5. whitened with 35% hydrogen peroxide and implemented 10% sodium ascorbate [Group A5 and Group B5]. After the restorations were done with a composite (Clearfil ST, Kuraray), they were shear-tested until failure. Two-way analysis of variance (ANOVA) test and Tukey's multiple comparisons test were used to check shear bond strength data at a significance level of p= 0.05. RESULTS Shear bond strength values of used bonding systems immediately after bleaching to whitened enamel, were significantly lower than those of non-whitened enamel (p<0.05). No statistically significant differences in shear bond strengths were found for two adhesive systems, when the antioxidant implemented groups were compared with the non-whitened group (Control) (p>0.05). Thus, the enamel bond strengths of the bonding systems were reversed following sodium ascorbate treatment. CONCLUSIONS It was concluded that the antioxidant sodium ascorbate application could fully neutralize the destructive actions of whitening agents on shear bond strength.en_US
