The antibacterial effect of herbal irrigant (Triphala) in comparison to different concentrations of Sodium Hypochlorite on Entrococcus faecalis

Abstract

Antimicrobial properties of endodontic irrigants influences the success rate of root canal therapy. Therefore, this study aimed to compare the antibacterial effect of herbal irrigant (Triphala) with differen concentrations of Sodium Hypochlorite on Entrococcus faecalis. Methods and Materials: 200 plates of Muller Hinton agar medium divided into 5 groups of 38 simples for each test solution and 10 plates for positive control considered. On the each plate one strile disk of Beckman paper that containe 10 ?l from each test solution was placed and the diameter of the bacterial growth-free area around solutions was measured with consideration of 6 mm primary diameters. Results: Kruskal-Wallis analysis revealed that there was a significant difference in growth-inhibition area grade among experimental groups(p<0.05) triphala showed more growth-inhibition diameter in comparison with 0.5% sodium hypochlorite and 1% sodium hypochlorite (p<0.05)and there was no signifacant difference between triphala and 2.5% sodium hypochlorite and 5% sodium hypochlorite(p<0.05). Conclusions: 1.There were no signifacant difference between antibacterial effect two groups triphala and 2.5% sodium hypochlorite with triphala and 5% sodium hypochlorite on Enterococcus faecalis. 2.Triphala has more antibacterial efficacy than 0.5% sodium hypochlorite and 1% sodium hypochlorite on Enterococcus faecalis.
