Abstract The purpose of this study was to evaluate polymicrobial coronal leakage of mineral trioxide aggregate (MTA) and amalgam. There were 108 single-rooted teeth randomly divided into 3 groups of 32 teeth each and positive and negative control groups of 6 teeth and obturated with gutta percha and either Diaket (3M/ESPE, Seefeld, Germany), AH Plus (Dentsply, De Trey, Konstanz, Germany), or Ketac Endo (3M/ESPE). These groups were further divided into 2 subgroups of 16 teeth in which root ends were resected and obturated with either MTA or zinc-free amalgam. The samples have been incorporated in a dual-chamber leakage model with a polymicrobial marker of five facultative anaerobes on the coronal part. Leakage was observing during a period of 90 days. The least leakage was found in a combination of Diaket and MTA (76.9 ±14.8 days) followed by AH Plus and MTA (66.1 ± 18.7), Diaket and amalgam (60.0 ± 23.1), AH Plus and amalgam (56.9 ± 22.1), and Ketac Endo and MTA (42.1 ± 17.8), whereas the greatest leakage was observed in the Ketac Endo and amalgam group (40.0 ± 17.24). Samples filled with MTA showed significantly better sealing than samples filled with amalgam (p < 0.05).
