Aim: The aim of this study was to assess the antibacterial efficacy of three different herbal irrigants against Enterococcus faecalis. Materials and Methods: Single rooted teeth were extracted due to orthodontic and periodontal reasons. The teeth were then inoculated with E. faecalis. The teeth were randomly divided into three experimental groups and two control groups of six samples each. Group 1 specimens were treated with 5.2% sodium hypochlorite (NaOCL) for 30 min followed by 5 mmol/L Ethylenediaminetetraacetic acid (EDTA) for 5 min and saline as final irrigant. Group 2 specimens were treated with and 5.2% NaOCl for 30 min as final irrigant. Group 3 were treated with Morinda citrifolia (MC) for 30 min as final irrigant. Group 4 were treated with Azadiracta indica (AI) as final irrigant. Group 5 were treated with green tea (GT) for 30 min as final irrigant. The dentin specimens were carefully spread onto a microscope slide and stained with BacLight and examined in a confocal laser scanning microscope set to monitor fluorescein isothiocyanate and propidium iodide. A total of nine fields were examined for each treatment and the bacteria presented were counted. Statistical Analysis: Using the one-way ANOVA with multiple comparison, significantly less bacteria were found adhering to the samples treated with Neem followed by NaOCL, GT, MC, Saline. Results: AI treatment produced the maximum reduction in adherence of E. faecalis to dentin (9.30%) followed by NaOCl (12.50%), GT (27.30%), MC (44.20%) and saline (86.70%). Conclusion: Neem is effective in preventing adhesion of E. faecalis to dentin.
