ABSTRACT
Background:
Antioxidant application soon after bleaching process increases the shear bond strength (SBS) of composite resin to enamel.Aims:
The aim of the study was to evaluate the antioxidant effects of selenium alone and in combination with alpha-tocopherol (αT) and green tea (GT) on SBS of composite resin to enamel following in-office bleaching with 38% hydrogen peroxide (HP).Methods:
Sixty extracted human single -rooted premolar teeth were cleaned and embedded in acrylic resin blocks at the level of cementoenamel junction(CEJ) followed by bleaching with 38% hydrogen peroxide (HP) and arbitrarily divided into seven groups (n=10) for antioxidant application Group I (negative control) intact teeth, Group II (positive control) only bleaching, Group III 10% selenium (Se), Group IV 10% alpha tocopherol (αT), Group V 10% αT +10% Se, Group VI 10% Green tea (GT), Group VII 10%GT+10% Se. In all groups, self-etch adhesive was applied and composite restoration was done, and specimens were stored in distilled water for 24h followed by SBS evaluation. StatisticalAnalysis:
One-way analysis of variance and post hoc Tukey's tests were used (P < 0.05).Results:
The highest SBS was found in negative control Group I (intact teeth) and least in positive control Group II (bleached teeth), whereas in experimental groups, Group VII (GT + Se) showed highest followed by Groups V (αT + Se), III (Se), and VI (GT) and least in Group IV (αT).Conclusion:
Combination of selenium with green tea and alpha tocopherol enhanced the SBS of composite resin following in-office bleaching.
