Objective: The antibacterial effectiveness of four different sealers AH Plus, EndoRez, mineral trioxide aggregate (MTA) Fillapex, iRoot SP against Enterococcus faecalis was evaluated by time kill assay method in vitro. Materials and Methods: Four sealers are used in this study: An epoxy resin-based sealer, AH Plus (Dentsply, Maillefer, Switzerland), a polymethacrylate resin-based sealer, EndoRez (Ultradent, South Jordan, UT) and two calcium silicate-based sealers, MTA Fillapex (Angelus Solucxoes Odontologicas, Londrina, Brazil), iRoot SP (Innovative BioCreamix Inc., Vancouver, Canada). Each sealer was mixed according to manufacturer's instructions. Five mg of each sealer was added to sterile tubes separately and evaluated at 20 min, 24 h, 7 days, and 30 days. Two tubes were used as positive and negative. Results: At the 20 th min AH Plus and iRoot SP were bactericidal, MTA Fillapex, and EndoRez were ineffective at the 20 th min. At the 1 st day MTA Fillapex was ineffective and rest of the sealers was bacteriostatic. At the 7 th day, only MTA Fillapex showed bactericidal effect, AH Plus, iRoot SP and EndoRez were bacteriostatic. At the 30 th day, MTA Fillapex was still bactericidal, AH Plus, iRoot SP, and EndoRez were still bacteriostatic. Conclusion: All root canal sealers tested were effective against E. faecalis. Fresh iRoot SP and fresh AH Plus had bactericidal action against E. faecalis. EndoRez has bacteriostatic behavior against E. faecalis. MTA Fillapex was the only sealer that could be bacteriocidal at 7 th and 30 th day.
