Purpose: Aim of this study was to evaluate the effect different application methods of total-etch adhesives containing different solvents on microtensile bond strength to dentin.Material and Methods: Teeth were randomly divided into three groups according to adhesive systems and solvent type; each group was divided into two subgroups according to application method (n=10). Total-etch adhesives were applied with or without rubbing action and light cured. After bonding procedures resin composites were bonded and light cured. Specimens were subjected to thermocycle then microtensile force and obtained data were analyzed statistically.Results: Rubbing action significantly improved bond strength to dentin (p<0,001). Tertiary butanol containing adhesive showed highest bond strength values with or without rubbing action (p<0,05).Conclusion: Regardless of the adhesive system, rubbing of adhesive resins to dentin surface could increase bond strengths. Due to their high performances, adhesives containing tertiary butanol as solvent could be suggested.
