PERBEDAAN DAYA ANTIBAKTERI EKSTRAK DELIMA MERAH (Punica granatum) DENGAN NaOCl 2,5% TERHADAP ENTEROCOCCUS FAECALIS

Background. Enterococcus faecalis is often found in persistent endodontic infection. It is due to virulence of these bacteria. NaOCl 2,5% is commonly use as irrigation material, but it has toxicity effect and can irritate periapical tissues. Therefore, some studies to find natural materials that have antibacterial properties as an alternative root canal medicament need to be done. Pomegranate (Punica granatum) proven in the preliminary study which has been done that the MIC (Minimum Inhibitory Concentration) is 35% and MBC (Minimum Bactericidal Concentration) is 40%. Purpose. The aim of this study was to compare the effectiveness of antibacterial activity of the Pomegranate extract than NaOCl 2,5% against Enterococcus faecalis. Methods. This study is an experimental laboratory with post test only control group design using Enterococcus faecalis ATCC 29212. Agar diffusion test was used to check the antimicrobial activity of Pomegranate extract and NaOCl 2,5% by measuring the inhibition zone diameter of each treatment. Result. Diameter of bacterial inhibition zone formed Pomegranate Extract is greater than NaOCl 2,5%. Conclucion. The antibacterial activity of Pomegranate extract is greater than NaOCl 2,5% against Enterococcus faecalis. Keywords: Pomegranate extract (Punica granatum), NaOCl, Enterococcus faecali
