Background: To compare bacterial leakage of MicroHeat and continuous wave with and without endodontic sealer.
Methods: Thirty – eight single – rooted extracted mandibular premolars were selected and randomly divided into four experimental groups (n=8) and two control groups (n=3). Teeth were prepared with Mtwo NiTi files and obturated with MicroHeat or System B with or without endodontic sealer. Three teeth were used as positive controls (Ct+) and three intact teeth served as negative controls (Ct-). All samples were tested for bacterial infiltration every day for 60 days.
Results: On day 32 overall contamination value was 62,5% for Mseal, 75% for Mnoseal, 75% for SBseal and 37,8% for SBnoseal; after 60 days, the final contamination result was 100% for Mseal, Mnoseal and SBseal and 87,5% for SBnoseal.
Conclusions: At the end of the observation period, groups showed no statistically significant differences.
