Purpose: To evaluate the microtensile bond strengths (mu TBS) of two core composites; LuxaCore and Multi Core Flow, to root canal dentin when using different adhesive systems. Methods: Bonded specimens were allocated into six groups (N= 20) according to the combination of two core composites and three adhesive systems (All-Bond 2, Excite DSC and Contax). The materials were used according to the manufacturers' instructions. The mu TBS were measured using a universal testing machine with a crosshead speed of 1 mm/minute. Data were analyzed utilizing two-way ANOVA (alpha= 0.05). Results: Excite DSC showed the highest mean mu TBS, which was significantly different from those of All-Bond 2 and Contax in LuxaCore groups. Excite DSC showed the highest mu TBS but significant differences (P= 0.154) were not detected in MultiCore groups. There were significant differences in mu TBS between two resin composites (P< 0.001). With Contax, mu TBS of MultiCore Flow to dentin were significantly higher than those of LuxaCore (P= 0.003).
