Effect of Different Types of Surface Treatment on Shear Bond Strength of Two Luting Resin Cements to Alumina Base Ceramic %R %X Statement of Problem: One of the most important problems in dentistry is to produce a suitable bond between tooth and all ceramic restoration, but there is little information on the use of resin cements and the importance of different surface treatments on their adhesion to high alumina containing ceramics.Purpose: The aim of this study was to find the optimal choice of surface treatments and luting cement for bonding to In-Ceram, an aluminum oxide reinforced glass ceramic material. The bond strength of two different luting cement to the ceramic material was evaluated. The effect of surface treatment, etching, sandblasting, and silanizing was also investigated.Materials and Method: Thirty In-ceram discs were fabricated and assigned to 3 groups. Group 1 specimens were treated with HF and Silane, Group 2 were sandblasted and then silane was applied, Group 3 were treated only with silane. Rely X cement was placed on all specimens and shear bond strength test was done.After the test, the discs were polished again and treated as previously mentioned in 3 groups. Then they received Panavia F cement and shear bond strength was evaluated using Instron testing machine.Results: Using Tukey HSD test, it was shown the Panavia F provided higher bond strength values than Rely X cement. One way ANOVA determined that the use of sandblast provided higher bond strength values than other groups. Surface etching with 9.5% HF also increased bond strength in comparison with silanization alone.Conclusion: Based on the results of this study, the use of Panaiva F was better for In-Ceram restorations. Sandbalsting is preferred to etching for the increase of bond strength of resin cements to alumina ceramic. Key words: Resin cement, Surface treatment, Shear bond strength, all ceramic restoration %U https://dentjods.sums.ac.ir/article_41464_48ec9e262a681e84d753a811745f6ab9.pdf
