Evaluación de la capacidad de selle de tres cementos endodoncticos con microfiltración bacteriana: E Faecalis

Abstract

Introduction: The filling of the root canal system must provide a tridimensional seal so it prevents de bacterial microleakage and the endodontic failure. Recently there have been introduced some endodontic sealers based on epoxic resins (Adseal) and MTA (Fillapex) from which there is not enough literature that enables it’s use. Objective: Asses the sealing ability of three endodontic sealers (Topseal, Adseal and Fillapex) through bacteria microleakage with E. Faecalis.Materials and Methods: Experimental in vitro study. 49 single root teeth were divided into 5 groups, 3 experimental groups (n=15 each) and 2 control groups (n=2 each). Teeth were cleaned, instrumented and filled with gutapercha and endodontic sealer according to the study group, group 1 (Topseal), group 2 (Adseal), group 3 (MTA Fillapex). The samples were mounted on a double chamber system and were inoculated every 2 days with E. Faecalis for 60 days.Results: The endodontic sealers Topseal and Adseal showed the least leakage compared with MTA Fillapex with a significance level (p=0.02). Conclusions: None of the endodontic sealers evaluated showed a full sealing ability; Topseal and Adseal are superior to MTA Fillapex regarding it’s sealing ability.
