Abstract: Objective. To evaluate the effects of different root-canal sealers on the bond strength of a fiberglass post cemented with self-adhesive resin cements. Material and methods. Forty extracted maxillary single-rooted canines were prepared with the crown-down technique and randomly divided into four groups according to the tested sealer: Group 1: control group, guttapercha cone only ( no sealer); Group 2: EndoREZ; Group 3: Sealapex; Group 4: Endofill. The roots were obturated with the gutta-percha cone using the cold lateral compaction technique. Fiberglass posts were cemented into the prepared post spaces with the self-adhesive cement RelyX Unicem. Bonded specimens were sectioned into 1-mm thick slabs and a push-out test was performed in a universal machine. Results. Data were subjected to ANOVA and Tukey tests (alpha = 0.05). No significant difference was detected between Groups 1-3 (P > 0.05). Group 4 showed a lower bond strength than the other sealers (P < 0.05). Conclusions. Endofill negatively interfered with the bond to root dentine; however, EndoRez and Sealapex did not affect the bond strength of the fiberglass post cemented with self-adhesive resin cements.
