Comparison of the antibacterial efficiency of neem leaf extracts, grape seed extracts and 3% sodium hypochlorite against E. feacalis - An in vitro study.
BACKGROUND
E. faecalis is the predominant micro-organism recovered from root canal of the teeth where previous endodontic treatment has failed. Thorough debridement and complete elimination of micro-organisms are objectives of an effective endodontic treatment. For many years, intracanal irrigants have been used as an adjunct to enhance antimicrobial effect of cleaning and shaping in endodontics. The constant increase in antibiotic-resistant strains and side-effects of synthetic drugs has promoted researchers to look for herbal alternatives. For thousands of years humans have sought to fortify their health and cure various illnesses with herbal remedies, but only few have been tried and tested to withstand modern scientific scrutiny. The present study was aimed to evaluate alternative, inexpensive simple and effective means of sanitization of the root canal systems. The antimicrobial efficacy of herbal alternatives as endodontic irrigants is evaluated and compared with the standard irrigant sodium hypochlorite.


METHODS
Neem leaf extracts, grape seed extracts, 3% Sodium hypochlorite, absolute ethanol, Enterococcus faecalis (ATCC 29212) cultures, Brain heart infusion media. The agar diffusion test was performed in brain heart infusion media and broth. The agar diffusion test was used to measure the zone of inhibition.


RESULTS
Neem leaf extracts and grape seed extracts showed zones of inhibition suggesting that they had anti-microbial properties. Neem leaf extracts showed significantly greater zones of inhibition than 3% sodium hypochlorite. Also interestingly grape seed extracts showed zones of inhibition but were not as significant as of neem extracts.


CONCLUSIONS
Under the limitations of this study, it was concluded that neem leaf extract has a significant antimicrobial effect against E. faecalis. Microbial inhibition potential of neem leaf extract observed in this study opens perspectives for its use as an intracanal medication.
