Purpose: To compare the efficacy of EDDY, XP-Endo Finisher R (XPFR) and EndoUltra in removing Enterococcus Faecalis (E.Faecalis) from oval root canals with standard needle irrigation (SNI).Methods: Seventy-two teeth with single rooted and single oval-shaped root canal were selected. Teeth were sterilized in autoclave, then were infected with E. faecalis and inoculated in an incubator at 37°C for 7 days. 4 teeth were processed for SEM analysis to control biofilm formation. Remaining 68 teeth were prepared with Reciproc Blue 25.08 and 40.06 files and then divided into 4 groups according to the irrigation activation techniques used: EDDY, EndoUltra, XPFR and SNI (n=17).Before (S1) and after (S2) irrigation techniques the bacterial samples were taken from the root canals and Colony forming units (CFUs) were counted and calculated in CFU/ml. The data were statistically analyzed with the Shapiro Wilk, Kruskal-Wallis test and Wilcoxon tests (p=0.05).Results: It was observed that CFU counts decreased significantly from S1 to S2 (p<0.05).However, there was no significant difference among the irrigation activation techniques in terms of removing E. faecalis (p>0.05).Conclusion: The efficiency of EDDY, EndoUltra, XPFR and SNI in the removal of E. faecalis was similar.
