Abstract: Purpose: This study investigated the effect of eugenol-containing temporary cement on the bond strength of two resin composite core materials (FluoroCore and Ti-Core) to dentin. Materials and Methods: Dentin was exposed in three groups of extracted teeth (20 specimens each]. In group one, dent in was covered with eugenol-containing temporary cement; the second group was covered with eugenol-free temporary cement; and the third group was left uncovered and served as a control group. All specimens were stored for 1 week at 37°C and 100% humidity. The dent in surfaces were cleaned and treated using the GLUMA adhesive system, followed by placement of composite core build-ups. Debonding of t he core material was accomplished using the Accuforce Elite test system. Results: There was a significant reduction in bond strength for the specimens covered with eugenol temporary cement (p < .0001), but no significant difference was found between the control group and the group treated with eugenol-free temporary cement. Bond strength of the Ti-Core material to dentin was significantly higher than that of FluoroCore (p <.0001). Conclusion: Pretreatment of the dentin with eugenol-based temporary cement adversely affects the bond strength of resin composite core material to dentin.
