Bacterial leakage assessment of bioceramic sealers

Aim: To assess the bacterial leakage of two bioceramic sealers and compare them to an epoxy resin-based sealer. Methodology: A sample of 94 one-rooted premolars was obtained and separated into three experimental groups of 30 teeth; two samples were used for negative controls and two for positive controls. The experimental groups were obturated using the hydraulic compaction technique: Group 1 AH Plus (R) sealer, Group 2 Bioroot (R) RCS and Group 3 TotalFill (R) BC Sealer. The teeth were mounted on bacterial leakage devices and incubated at 37 degrees C for 30 days in a bilin esculin agar culture with Enterococcus Faecalis. Results: Leakage occurred in 27 roots (30%) of the entire sample. Group 1 (AH (R) Plus) showed the highest percentage of leaked samples (40%) and also took the least average days to leak (16,9) compared to Bioroot (R) (19,7) and TotalFill (R) (19,5), but the differences found were not significant (p>0,05). Conclusions: None of the sealers analyzed in this study produced an effective apical seal in which no bacterial leakage occurred. A third of the total sample presented leakage, but the differences between groups were not significant.

Automated summary

This study aimed to assess bacterial leakage of two bioceramic sealers compared to an epoxy resin-based sealer. Results showed none of the sealers provided a completely effective apical seal, with leakage occurring in around 30% of the total sample, but differences between groups were not significant.
