Aim:
Even after a complete root canal therapy, reinfection may occur as a result of incomplete seal and activation of residual bacteria. Thus, antimicrobial activity is an important characteristic of root canal sealers. MTA Fillapex is a newly developed MTA-based sealer. It has been subjected to various studies evaluating its physical and chemical properties. In this study, we aimed to compare the antimicrobial activity of this sealer to the commonly known widely accepted sealer, AH26.
Methods:
MTA Fillapex and AH 26 were exposed the bacterial suspension of Enterococcus faecalis, Escherichia coli, Streptococcus mutans, and Candida albicans after setting. After incubation and complete evaporation, BHI was added to microtubes. 24 hours later, the liquid content was placed in agar diffusion plate and bacterial count was performed. ANOVA followed by Tukey test, and t-Test were performed to analyze the data.
Results:
With regard to all four bacterial groups, the bacterial count was significantly lower in MTAFillapex group comparing to AH 26 group.
Conclusion:
Newly developed MTA Fillapex sealer, has better antimicrobial properties in comparison to the widely accepted AH26 sealer.
