Abstract
|
|
|
|
Antimicrobial activity of extract from some traditional oriental medicinal plants were evaluated for their antimicrobial activity against six oral pathogens, Streptococcus salivarius, Streptococcus oralis, Streptococcus mutans, Streptococcus sanguinis, Lactobacillus acidophilus and Lactobacillus casei, which are associated with caries disease. The antimicrobial activity was examined by determining the inhibition zone using the disc diffusion assay. In antibacterial activity test, extracts of Scutellaria baicalensis, Chrysanthemum indicum, Kochia scoparia, Hydnocarpus anthelmintica and Caesalpinia sappan showed inhibitory effects (40 mg/ml) against tested caries bacteria. Especially, the C. sappan extract showed the strongest activity on S. oralis (40 mm), L. casei (35 mm) and S. mutans (28 mm). Thus, this result suggests that C. sappan may be applicable to preventing dental caries.
