COMPARATIVE EVALUATION OF APICAL SEALING ABILITY OF DIFFERENT ROOT CANAL SEALERS
Purpose: The aim of this study was to compare the short and long term apical sealing ability of different root canal sealers.
Materials and Methods: Fifty-five extracted human anterior single-root teeth were used. The coronal part of each tooth was removed and the root canals were prepared with NiTi rotary instruments. Teeth were divided into 5 study groups; Group I: MTA Fillapex®; Group II: Sealapex® and Group III: AH Plus® (n=15) and negative and positive control groups (n=5).The quality of root canal sealing was assessed by a fluid filtration method performed at 24 h and 180-day time intervals. Kruskal Wallis and Mann Whitney U tests were used to compare the groups.
Results: At 24 h evaluation, MTA Fillapex presented significantly less microleakage than the Sealapex and AH Plus (p<0.05). At long term interval (180-day), Sealapex and AH Plus® presented significantly less microleakagethan the MTA Fillapex (p<0.05).
Conclusion: Sealapex and AH Plus showed significantly better sealing abilities than MTA Fillapex in long term assesment.
