AbstractAims: To evaluate the eﬀect of three diﬀerent adhesive syﬆems on shear bond ﬆrength of composite resin to Er,Cr:YSGG lased dentin. Materials and methods: Twenty one sound third molars were used. Occlusal third of crowns was cut using minitom machine to expose ﬂat dentin surface. Laser irradiation was performed on a circular teﬆ area demarcated on each dentin surface. Samples randomly assigned to three groups (n=7) according to the adhesive syﬆems that used which were: total etch adhesive (Adper single bond, 3M ESPE), two ﬆep self etch adhesive (Clearﬁl SE bond, Kurary), and all in one adhesive (Adper easy one, 3M ESPE). Adhesives were applied to the lased dentin surface according to manufacture inﬆruction. Composite rod was applied over the bonded area and cured. Samples were ﬆored in diﬆilled water at 370for 24 hours. The evaluation of shear bond ﬆrength was employed by the use of universal teﬆing machine. Results: Statiﬆical analysis of data by analysis of variance (ANOVA) teﬆ and Duncanes multiple range teﬆ revealed no signiﬁcant diﬀerence in the shear bond ﬆrength between the adhesive syﬆems (P≤ 0.05). Conclusions: The results show that all the teﬆed adhesive syﬆems have relatively the same eﬀect on the shear bond ﬆrength of composite resin to lased dentin surface.
