Introduction: The aim of the study was to evaluate the bacterial leakage of four different bioceramic root canal sealers and to compare it to the conventional epoxy resin-based sealer. Materials and Methods: The study sample consisted of 94 single-rooted human teeth with one round root canal, which were instrumented and randomly distributed into five experimental groups according to the root canal sealer: Group 1: TotalFill bioceramic sealer; Group 2: BioRoot root canal sealer; Group 3: mineral trioxide Aggregate (MTA) Fillapex; Group 4: MTA Plus; Group 5: epoxy resin-based sealer AH Plus and positive and negative control group. The prepared samples were fixed in a model designed for the Enterococcus faecalis leakage evaluation and were sterilized in plasma. The bacterial penetration through the filled root canals was checked by the color change in the lower tube during 60 days. The scanning electron microscopy was used to check the bond between the sealer and the dentine wall. Data were statistically analyzed. Results: Total Fill bioceramic sealer (BCS) group presented significantly lower number of samples that leaked (14.2%) compared to the AH Plus group (78.6%) (P = 0.002) and MTA Plus group (50%) (P = 0.046). There was no statistically significant difference between other groups (P > 0.05). Conclusion: The TotalFill BCS root canal sealer provided better sealing ability compared to the AH Plus and the MTA Plus sealers.
