Objective:To study the role of Galla Chinensis for the initiative adherence of Actinomyces as a preparation for screening an effective plaque control agent. Method:Actinomyces ATCC 19246 were chosen as the experiment strain,and radiolabeled with~3H-thymidine. The numbers of~3H labeled bacteria attached to S-HA were counted by scintillation counting to indicate the amount of adherence. A four-organism bacterial consortium was grown in a biofilm model and exposed to repeated solution pulsing respectively. After 6 pulses, the biofilm surface structure was observed with the scan electron microscope and the population on the biofilm was enumerated. Results:Galla Chinensis can inhibit the initiative adherence of Actinomyces effectively. Conclusions:Galla Chinensis might work as a potential plaque control agent.
