The aim of this study was to evaluate the bond strength between composite resin and dentin using different bond systems. Sixteen human molars extracted were selected. Each tooth was vertically cut in 3 dentin fragments of 2 mm of thickness (n=42) and randomly divided among the groups. Groups 1 was used Adper Single Bond 2, for groups 2 Silorano primer, groups 3 Adper SE Plus, and 4 Scotchbond Multiuse. Two composite resin cylinders were built up on each dentin surface (n=10) and subjected to a micro shear bond strength test until failure. To evaluated the results were used the Kruskal-Wallis OneWay Analysis of Variance and Tukey Test (p=0.05). Kruskal-Wallis test evidenced at least one statistical significant difference (p=0.001). The Tukey test showed statistical significant differences among the group (P<0.05). Group 1 showed statically significant higher results when compared with group 4. The results of this study evidenced that the adhesive system can effect the bond strength between silorano-based composite resin and dentin.
