Aim: This study aimed to evaluate the influence of different root canal drying protocols on the bond strength of a bioceramic sealer, in comparison with an epoxy resin-based sealer.

Methodology: Sixty-six mandibular premolar teeth had their crowns sectioned and their canals prepared with Reciproc (VDW GmbH). Next, the roots were randomly distributed into three groups (n=22), according to the different drying protocols: absorbent paper points (GPP); irrigation with 95% ethanol and drying with paper points (G95E); and irrigation with 70% ethanol and aspiration with a 30-gauge needle (G70E). Each group was then redistributed into two subgroups (n=11), according to the sealer used in the single cone technique: Sealer Plus BC (MK Life) or AH Plus (Dentsply). After 7 days of obturation, the roots were sectioned into 1-mm thick slices and submitted to the push-out test. Bond strength was calculated (MPa) and data were analyzed by Kruskal-Wallis test, complemented by Games-Howell post-hoc test and Mann-Whitney U test (α=5%).

Results: There was no statistical difference among the drying protocols in the specimens filled with AH Plus, irrespective of the root third (P>0.05). For the Sealer Plus BC, no significant difference was observed for the drying protocols, however, there was statistical difference among the root thirds in G95E (P=0.017). When the sealers were compared to each other, no statistical difference was observed, regardless of the drying protocol evaluated: GPP (P=0.447), G95E (P=0.687) and G70E (P=0.132).

Conclusions: The different drying protocols of the root canal did not influence the bond strength of both endodontic sealers.
