PERBEDAAN EFEKTIVITAS CHLORHEXIDINE GLUKONAT 0,2% DENGAN TEH HIJAU (CAMELLIA SINENSIS) TERHADAP JUMLAH PORPHYROMONAS GINGIVALIS

Background: Periodontitis is a periodontal inflammation caused by plaque that contains pathogens, Porphyromonas gingivalis is one of them. Chlorhexidine therapy used to reduce the number of pathogenic bacteria causing periodontitis. Green tea contains polyphenols such as epigallocatechin-3-gallic as antibacterial agent that can kill the bacteria Porphyromonas gingivalis. This study aims to determine differences in the effectiveness of chlorhexidine gluconate 0.2% with green tea (Camellia sinensis) various concentrations to decrease the amount of bacteria Porphyromonas gingivalis.Method: This research was experimental with post test only design. Method used in antibacterial test was a drop plate misra. The experimental group consisted of six groups: chlorhexidine gluconate 0.2% and green tea group with a concentration of 100%, 75%, 50%, 25% and 12.5%. minimum bactericidal concentrations againts Porphyromonas gingivalis was evidenced by counting the number of colonies that formed on agar. Analysis data was using One Way ANOVA continued by Post hoc tests Tamhane.Result: The results showed that chlorhexidine gluconate 0.2% with green tea effective to decrease the amount of bacteria Porphyromonas gingivalis(ANOVA p
