Abstract:
Introduction: The success of the endodontic treatment is closely associated with eliminating endodontic microbiota especially bacteria like Enterococcus Faecalis (E. Faecalis). Irrigation solutions are suggested for this purpose but there are contraries regarding irrigations and their concentrations. This study aimed to compare antibacterial efficacy of irrigations including ۲.۵% Sodium hypochlorite (NaOCl), ۲% Chlorhexidine (CHX), and ۱.۵% Hydrogen peroxide (H۲O۲). Methods: Fifty deciduous human extracted teeth were divided into ۳ groups of ۱۵ teeth, ۲.۵% NaOCl, ۲% CHX, ۱.۵% H۲O۲, and ۵ teeth in the negative control group. Later, root canals were inoculated by E. Faecalis. After cleaning and shaping, we irrigated the root canals of the teeth in each group with NaOCl, CHX, and H۲O۲. Samples were obtained again and sent for microbiological evaluation. Wilcoxon signed-rank test, Paired sample T-test, and Kruskal–Wallis were used to analyze data. Results: All ۳ groups showed significant bacterial reduction (p <۰.۰۵). NaOCl and CHX showed no significant difference (P=۰.۴۱۵). But the reduction of these ۲ groups was higher than H۲O۲ (p Conclusions: ۲.۵% NaOCl and ۲% Chlorhexidine showed considerable efficacy against E. Faecalis while ۱.۵% Hydrogen peroxide was not able to eradicate all of E. Faecalis colonies. Hence, NaOCl and CHX solutions can be used for decontamination of infected root canals
