Most of periodontal diseases are caused by periodontopathogens such as Porphyromonas gingivalis which can cause chronic form of periodontitis and generalized agressive periodontitis. White turmeric (Curcuma zedoaria) which can be found easily in Indonesia has antibacteria effect againts oral pathogens. This study is aimed to examine the inhibitory effect of methanol extract of white turmeric againsts Porphyromonas gingivalis.
This study was a laboratory experimental. Methanol extract of white turmeric at
100%, 50%, 25%, 12,5% and 6,25% concentrations were tested on Porphhyromonas gingivalis ATCC 33277 using well-diffusion methode on blood agar enriched with hemin and vitamin K with three times of repetition.
The result of this preliminary study shows that methanol extract of white turmeric at
100%, 50%, 25%, 12,5% and 6,25% concentration have the average diameter of inhibition respectively 10,48±5,35 mm, 2,45±1,05 mm, 1,9±1,24 mm, 0,85±1,03 mm, and 1,56±1,85.
According to the result of this study, it could be concluded that methanol extract of white turmeric tends to have inhibitory effect againts Porphyromonas gingivalis.
