Coronal microleakage of two root end filling materials using a polymicrobial marker

The purpose of this study was to evaluate polymicrobial coronal leakage of 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, AH Plus or Ketac Endo. These groups were further divided into 2 subgroups of 16 teeth 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 5 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), Ketac Endo and MTA (42.1± ; ; ; ; 17.8) while the greatest leakage was observed in Ketac Endo and amalgam group (40.0± ; ; ; ; 17.24). Samples filled with MTA showed significantly better sealing than samples filled with amalgam (<0.05).
