Introduction: Endodontic infections are polymicrobial in nature. Enterococcus fecalis is the most common micro-organism isolated from failed endodontic cases. The constant increase in antibiotic resistant strains and side effects caused by synthetic drugs has prompted researchers to look for herbal alternatives since the gold standard for irrigation i.e., sodium hypochlorite (NaOCl) has many disadvantages. Objective: The present study was aimed to explore newer irrigation solutions, which would probably be as effective as NaOCl. Materials and Methods: Extracted human single rooted premolar teeth were biomechanically prepared, vertically sectioned, placed in tissue culture wells exposing the root canal surface to E. fecalis is grown on Mueller Hinton agar plates to form a biofilm for 6 weeks. At the end of 6 th week, all seven groups were treated with 3 ml of test solutions and control for 10 minutes and evaluated for E. fecalis growth and number of colony forming units. Results: Propolis, NaOCl and triphala showed no statistically significant difference, whereas all the other inter-group differences were statistically significant (Tukey's honest significant difference (HSD)) (P < 0.001). Conclusion: Propolis and triphala were found to be as efficacious as NaOCl. The use of herbal alternatives as root canal irrigation solutions might prove to be advantageous considering several unfavorable properties of NaOCl.
