Abstract

 Statement of the Problem: The bond strength of composites with different adhesive systems with dentin is an important factor in long term durability of composite restora-tions. The effect of titanium tetrafluoride (TIF4) as anti caries agent and sodium hypo-chlorite (NaOCl) as disinfectant on the shear bond of nanofilled and silorane based composite resins have not been investigated in previous studies.Purpose: This study was conducted to determine bond strength between dentin and two composite systems, by means of shear bond test using TIF4 and NAOCL.Materials and Method: Middle dentin of 60 intact extracted maxillary premolar teeth were exposed by sectioning the crowns at a depth of 2mm from central groove and parallel to the occlusal surface. Standardized smear layer was created using a 600-grit silicon carbide paper and then samples were embedded in acrylic resin blocks. Then the samples were randomly divided into 6 \groups summarized as Group I: Z350, Group II: Z350+NaOCl, Group III: Z350+TIF4, Group IV: P90, Group V: P90+NaOCl, Group VI: P90+TIF4 according to manufacturer’s instruction. Then samples were subjected to SHEAR BOND STRENGTH (SBS) test using universal testing machine and data were analyzed using ANOVA and Tukey tests (p<0.05).Results: Application of 5% NAOCL caused a significant decrease in SBS of NANOFILLED COMPOSITE resin (p=0.004), and also silorane based composite resin (p=0.006). Appli-cation of 4% TIF4 caused a significant increase in SBS of silorane based composite resin (p=0.001). The effect of TIF4 on NANOFILLED COMPOSITE was not statistically sig-nificant.Conclusion: Using TIF4 has a positive effect on increasing the shear bond while NAOCL has negative effect on bond strength.
