AbstractAims: 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.
