Comparison of Shear Bond Strengths of Two type Composite Resins to Porcelain with Different Adhesives (Methacrylate base and Silorane base)

Abstract

The aim of the present study was to compare the shear bond strengths of two types of composite resins (methacrylate-based and silorane-based) to porcelain using three adhesive types (two methacrylate-based and one silorane-based adhesive). Materials and methods: In the present study, 156 samples of feldspathic porcelain surfaces were prepared with air-abrasion and randomly divided into 6 groups (n=26). In groups 13 Z250 composite resin was used to repair porcelain samples with Adper Single Bond 2(ASB), Clearfil SE Bond (CSB) and Silorane Adhesive(SA) as the bonding systems, respectively, after application of silane. In groups 46, too, the same adhesives were used in the same manner for the same purpose with Filtek Silorane composite resin. Finally, the shear bond strengths of the samples were measured. Two-way ANOVA and post hoc Tukey tests were used to analyze dataEs. Results: The results of two-way ANOVA showed significant differences in the mean bond strength values in terms of the adhesive type (P<0.001). Post hoc Tukey tests revealed significant differences in results between the ASB and CSB (P<0.001), with higher bond strength values with the use of ASB. In addition, significant differences were observed between groups bonded with CSB and SA (P<0.001). No significant differences were observed between the SA and ASB. There were no significant differences in repair bond strength values in terms of the composite resin type. Conclusion: The results of the present study showed the highest repair bond strength values to porcelain with both composite resin types with the application of SA and ASB
