ABSTRACTBackground: Chronic periodontitis is an infectious disease caused by bacterial colonization of dental plaque. Bacteria that play a role in chronic periodontitis is Porphyromonas gingivalis. One of mouthwash that reduce the number of P.gingivalis colonies is chlorhexidine 0.2%. Long term use of chlorhexidine 0.2% can cause some side effects to the oral cavity, so we need an alternative mouthwash from natural ingredients that can reduce the side effects of chlorhexidine 0.2%. Ulin bark extract contains phenolic, flavonoid, tannin, alkaloid, terpenoid, and saponin which can be an alternative base for mouthwash besides chlorhexidine 0.2%. Purpose: It is to analyze antibacterial effectivity of ulin bark extract on the growth of Porphyromonas gingivalis. Methods: This study was using true experimental research and post-test only with control group design, that used 9 treatment groups with 4 replications, that were 5%, 10%, 20%, 40%, 60%, 80%, 100% concentrations, chlorhexidine 0.2%, and sterile aquadest against P. gingivalis. The total samples were as many as 36. Result: One Way ANOVA and Post-Hoc Games Howell tests showed that the average absorbance values has a significant difference, then Kruskall Wallis and Post Hoc Mann Whitney tests showed the number of colonies with significant differences. MIC in this study was at 5% concentration and MBC was at 20% concentration.. Conclusion: Ulin bark extract with 40% concentration has an absorbance value equivalent to 0.2% chlorhexidine and 20% concentration has a bactericidal effects equivalent to 0.2% chlorhexidine against the growth of P.gingivalis.Keywords:Antibacterial, Dilution method,Porphyromonas gingivalis, Ulin Bark Extract.

ABSTRACTBackground: Chronic periodontitis is a periodontal disease with 80% of all cases of periodontitis. The major causes are the accumulation of plaque and bacteria. The dominant bacteria in chronic periodontitis is Porphyromonas gingivalis. Treatment of chronic periodontitis can be done by scaling and root planing and supporting therapy by using mouthwash such as Chlorhexidine gluconate 0.2% which is the gold standard in the treatment of periodontal disease. Chlorhexidine gluconate 0.2% has disadvantages so that nowadays research on herbal plants is being done to find alternative medicines that are more effective. Ramania (Bouea machropylla Griffith) leaf contains flavonoids that have antibacterial properties. Objective: To analyze the antibacterial effectivity of the flavonoid fraction of Ramania leaf extract against Porphyromonas gingivalis that causes chronic periodontitis. Method: True experimental study and post-test with control group design consisting of 5 treatment groups, namely flavonoid fraction of ramania leaf extract with concentrations of 0.1%, 0.3%, and 0.5%, chlorhexidine gluconate 0.2% as a control positive and aquadest as a negative control. Each group was repeated 6 times. Antibacterial tests using the dilution method with inhibitory rates calculated using a UV-Vis spectrophotometer and killing rates were calculated using a Colony Counter. Results: The average difference in absorbance values obtained inhibitory rates at concentrations of 0.1%, 0.3%, and 0.5%. One Way Anova Test showed a significance value of 0,000 (p < 0.05). The average number of colonies after 24 hours incubation showed the results of a kill rates in the concentration group of 0.3%, 0.5%, and positive control. The Kruskal Wallis test showed a significance value of 0,000 (p < 0.05).
