Objectives: The aim of this study was the comparison of antibacterial effectiveness of three endodontic sealers, used in endodontic therapy. The antibacterial effectiveness of sealers was determinate by measuring the inhibitory halo against Enterococcus faecalis. Material and methods: A comparative in vitro study was done; the method of agar diffusion of Müller- Hinton was used. A sample of 10 replications for each sealer was estimated with the help the program (G Power 3.1) the total of sample was the 30 units of study. The data of inhibitory halo was measured in millimeters after 24 hours, incubated a temperature of 37°C, the results was registered in a format developed by the author, later the results were processed by statistical analysis Shapiro-Wilk, Kruskal-Wallis and U de Mann Whitney. Results: The resin- based sealer (TOPSEAL) showed an inhibitory halo of 7.7 mm; the hydroxide of calcium - based sealer (SEALAPEX) was of 6.0 mm whereas the oxide of zinc and eugenol - based sealer showed an inhibitory halo of 8.4 mm, this inhibitory halo was the biggest in this study. Conclusions: This study concluded that the sealers used in this study are not equal in their antibacterial effectiveness against Enterococcus faecalis.
