Abstract
Porphyromonas gingivalisis one of the anaerobic bacteria that are found in patients with periodontitis. Green tea catechins have antibacterial activity against several oral pathogenic bacteria. This study aimed to determine the ability of the green tea extract fraction to inhibit the growth of P. gingivalis. The green tea powder was extracted with hexane by maceration, then the insoluble fraction of the hexane was extracted using high-pressure extraction with water as a solvent ratio of 1:10. Antibacterial activity test was carried out by agar dilution method and agar diffusion disk using Mueller-HintonAgar (MHA) media. The results showed that green tea extract had antibacterial activity against P. gingivaliswith an inhibitory value of at least 0.5% (5mg / ml) and an average diameter of the zone of inhibition at a concentration of 4 mg/disc of 16.16 mm. This study concludes that green tea extract can be made in a dosage form to prevent periodontitis.
