RESUMO

The aim of this study was to evaluate the effectiveness of different chemo-mechanical systems for root canal preparation Self-adjusting File (SAF), TiLOS Anatomic Endodontic Technology System (TiLOS), and Mtwo against Enterococcus faecalis in the canal. Forty seven human mandibular bicuspids were contaminated with E. faecalis (ATCC 29212) for 21 days and divided into groups according to preparation methodÇ SAF group with continuous irrigationç TiLOS;Endo-Eze group and irrigation with a NaviTip needle Mtwo group and irrigation eith NaviTip. The irrigant used was 2.5% NaOCl. Bacterial harvests were performed after the contamination period (initial harvest), immediately post-preparation, and seven days after chemo-mechanical preparation. Data were expressed as CFU and subjected to ANOVA and Tukey or Kruskal-Wallis and Dunn tests at P <0.05. Reduction in E.faecalis was observed after preparation (P<.05), with no significant differences between the groups (P>.05). The final harvest demonstrated statistically similar increase in the bacterial counts in all groups. Root canal preparation using SAF, TiLOS;Endo-Eze, and Mtwo systems contribute for the disinfection of the root
