Avaliação ex vivo do selamento apical marginal do mta Fillapex®

Abstract

Objective: The present ex vivo study aimed to assess the apical sealing ability of the endodontic sealer MTA FILLAPEX ® compared to Sealapex, Pulp Canal Sealer, and AH26.methods: The ability to prevent leakage of a culture of Enterococcus faecalis through the root canal obturation was assessed. Forty-eight single-rooted teeth that had been extracted from humans were used. Following instrumentation and obturation using the warm gutta-percha vertical condensation technique, the teeth were allocated into one of four experimental groups (n=10), a positive control group (n=4), or a negative control group (n=4). The microbial inoculation was performed every three days over 60 days. The data were tabulated and subjected to statistical survival analysis, whereby the performance of the four investigated sealers was compared using the log-rank test.
