This study evaluated the effectiveness of conventional needle irrigation and three different irrigant activation methods in reducing <i>E. faecalis</i>. <b><i>Methods:</i></b> The root canals of extracted teeth were shaped, contaminated with <i>E. faecalis</i>, and incubated for three weeks. They were randomly allocated to four experimental groups of 15 teeth each according to the final irrigation method: group 1, conventional needle irrigation; group 2, passive ultrasonic (PU) irrigation; group 3, XP-endo Finisher (XPF); and group 4, laser-activated (LA) irrigation. Bacterial samples were taken and cultured before and after these final irrigation procedures. The colony-forming units were counted, and the bacterial reduction percentages of each group were calculated. The Kruskal-Wallis and Dunnet tests were used for statistical analysis. <b><i>Results:</i></b> All irrigant activation methods were significantly more effective than conventional needle irrigation. Although the LA group generated more negative samples than PU, there was no statistically significant difference between the LA and PU groups. LA was significantly more effective than the XPF, whereas PU and XPF were statistically similar. <b><i>Conclusions:</i></b> Within the limitations of this study, the final irrigation with LA and PU showed the best reductive effect on <i>E. faecalis</i> colonies.
