| Summary: | Objectives: The aim of this study is to determine the effect Bioactive Glass (BAG) on dentinal shear bond strength (SBS) of composite resin.
Materials and Methods: 120 healthy and intact third molar teeth were selected for this study. Superficial dentin was revealed from 3mm above CEJ by cross sectioning. Then the samples according to the bonding technique and the time of shear bond strength test (after 24 hours, after 3 months of storage in distilled water) were divided into six main groups. Then composite resin applied on exposed dentin surface in 1 mm plastic tubes. The SBS of the samples in each batch was calculated at the initial time and after keeping in distilled water for 3 months with a universal testing machine). For Statistical; analysis Kruskal-Wallis and Mann-Whitney non-parametric tests with Ben Feroni correction were used. The significance level was p<0.05.
Results: In the initial time (after 24 hours), effect of adhesive application method (P=0.769), method of adding BAG particles (P=0.951) and the interaction between them (P=0.547) are not significant. During the storage time (3 months of storage in distilled water), effect of adhesive application method is not significant (P=0.417). effect of adding BAG particles is significant (P=0.002) and the interaction effect is not significant (P=0.820).
Conclusion: the use of bioactive glass nano particles (45S5) with a low percentage (1%) as a universal dental adhesive filler can increase the strength and maintain the durability of the bond to dentin. This effect is independent of the adhesive application technique.
