Abstract
AIM: The purpose of this in vitro study was to evaluate and compare the antibacterial activity and dentinal tubule penetration depth of three root canal sealers. MATERIALS AND METHODS: The sealers to be analyzed were Group I (AH Plus), Group II (RealSeal self-etch) and Group III (iRoot SP). Direct contact test (DCT) was used to assess the antibacterial activity of tested sealers when in contact with Enterococcus faecalis. The materials were examined after 7, 3, 1 day aging samples in phosphate-buffered–saline and freshly mixed. For dentinal tubule penetration depth 30 single rooted human incisiors were selected, divided into three groups (n=10) and filled with single cone technique using tested sealers. The specimens were sectioned longitudinally and prepared for observation using Scanning Electron Microscope. RESULTS: Group I showed significantly greater antibacterial activity as compared to Group II and III over a period of 7 days time. There was no statistically significant difference in antibacterial activity between Group II and III. The maximum mean penetration depth of Group III (108.57μm) was significantly higher than that of Group I (64.89μm) and II (63.53μm). There was no statistically significant difference in penetration depth between Group I and Group II. CONCLUSION: Within limitations of this study, the new ceramic based root canal sealer iRoot SP performed better as compared to existing resin-based sealers.
