Abstract

Objective-This study aimed to evaluate the antibacterial efficacy of two different formulations of propolis extract (30% Propolis in DMSO and 30% Propolis in Ethyl Alcohol) when used as an irrigant in the root canal system against Enterococcus faecalis and compare it that of 3.0% Sodium hypochlorite and 0.2% Chlorhexidine gluconate.Method and materials- Extracted single rooted human teeth were instrumented upto size 40.After removal of the smear layer, an inoculum of E.faecalis was inserted into the root canals. After incubation the inoculum was removed and the root canals were divided into five groups and irrigated with one of the following irrigants: 3.0% Sodium hypochlorite and 0.2% Chlorhexidine gluconate, 30% Propolis in DMSO and 30% Propolis in Ethyl Alcohol and saline (n==15). Samples were collected from the root canals. Ten samples from each group were subjected to turbidity check and five for counting colony forming units. Results- There was a statistically significant difference in the antibacterial action of 30% propolis in DMSO and 30% propolis in ethyl alcohol when compared to 3% sodium hypochlorite 0.2% chlorhexidene gluconate with respect to broth turbidity test however, no statistical significant difference was found among all the groups in cfu count test. Conclusion- Both the formulations of Propolis- 30% Propolis in DMSO and 30% Propolis in Ethyl Alcohol were not very effective against Enterococcus faecalis 0.2% Chlorhexidine Gluconate and 3.0% Sodium Hypochlorite showed the best and equivalent anti-microbial activity against E.faecalis.
