Aims: Tensile bond is important for assessing the success of adhesive restorative materials. The aim of this study is to evaluate the tensile bond strength of resin composite restoration to Er,Cr:YSGG lased dentin bonded with three types of adhesive systems. MATERIALS AND METHODS: Occlusal enamel of eighteen molars samples was removed to expose the underlining dentine. Er,Cr:YSGG laser irradiation was performed to central dentin. Samples were assigned randomly to three groups (N = 6): Group Ι: dentin was treated total etch adhesive (Adper single bond, 3M ESPE); Group II: treated with all in one self—etch adhesive (Adper easy one, 3M ESPE); Group III: treated with two step self—etch adhesive (Clearfil SE bond, Kurary). A translucent plastic tube was fixed and filled incrementally with hybrid resin then small metal screw with ring head was embedded in last increment. Samples were stored in distilled water at 37°C for 24 hours. Tensile bond strength was measuredd using universal testing machine (Digital Force Gauge IMADA CO., LTD, Japan), the failure mode was evaluated. Then statistical analysis was done include descriptive, one way analysis of variance test, and Post Hoc tests. RESULTS: A significant differences in tensile bond strength were observed among groups (p < 0.05). Total etch adhesive bonded demonstrate significantly higher tensile bond strength value than one step self–etch and two step self–etch adhesives (p < 0.05). No significant differences were observed between one step self–etch and two step self–etch adhesives (P>0.05). CONCLUSION: The tensile bond strength of resin composite to Er,Cr:YSGG lased dentin was influenced by adhesive type. Total etch adhesive bonded had higher tensile bond strength than one step and two steps self–etch adhesives.
