Streptococcus mutans (S. mutans ) is one of the most important bacteria in the formation of dental plaque and dental caries. S. mutans adheres to an acquired pellicle formed on the tooth surface, and aggregates with many oral bacteria, and initiates plaque formation by synthesizing glucan from sucrose, which is catalyzed by glucosyltransferases. S. mutans metabolizes the dietary sugar to the organic acids. The organic acids demineralize tooth surface and result in dental caries. Galla Chinensis have been traditionally used for stopping bleeding of gingiva, removing edema and halitosis, drainage, fixing the teeth and as an antiphlogistic agent. In previous reports, antibacterial effects of Galla Chinensis have been investigated whereas anti-cariogenic effects is still not examined enough. Therefore we tested effects of ethanol extracts of Galla Chinensis on the cariogenic properties such as the growth, acid production, adhesion, and insoluble glucan synthesis of S. mutans . In the result, ethanol extracts of Galla Chinensis showed the inhibition of S. mutans growth and organic acids production over 0.031 mg/ml concentrations. The adhesion of S. mutans to Saliva-coated Hydroxyapatite beads S-HAs has decreased with the increase of concentration of ethanol extracts of Galla Chinensis . And it seems to have adhesion inhibitory effect in concentration of over 0.25 mg/ml. It gives us the result that Galla Chinensis have anti-caries effects. But ethanol extract of Galla Chinensis didn"t have inhibitory effect on insoluble glucan synthesis. Preliminary phytochemical analysis of the ethanol extract of Galla Chinensis showed strong phenolic compounds, medium steroids & terpenoids and glycosides, and weak organic acids and peptides. These results suggest that the ethanol extracts of Galla Chinensis may have anti-cariogenic properties, which may be able to be related with strong phenolic compounds.
