Comparative Evaluation of Antimicrobial Efficiency of Various Herbal Root Canal Irrigants

Introduction: By reducing the bacterial load in root canals, irrigation contributes significantly to the disinfection of the root canal system. Objectives: The current research was done to assess antimicrobial efficiency of various herbal root canal irrigants against E. Faecalis. Materials and Method: Enterococcus faecalis, reference strain ATCC 19433, was combined and cultivated with root canal irrigating solutions containing sodium hypochlorite (NaOCl), triphala, turmeric, and garlic (Allium sativum). After being cultivated on bile auscline agar, the samples were incubated for 24 hours at 37°C. The colony-forming units (CFU) were calculated. A statistical analysis was performed on the collected data. Result: There was highest antimicrobial efficacy and greater reduction of CFU with group IV followed by groups II, I, and III. The difference was statically significant. Conclusion: Tested herbal irrigants were effective in reducing E faecalis count. They can be suggested to use alternative to NaOCl.
