    Abstract:
    OBJECTIVE: To investigate the effects of 5 kinds of natural medicine such as Radix et Rhizoma Rhei on the adherence of Streptococcus mutans to salivary acquired pellicle, and to screen effective natural medicines for the prevention of caries. METHODS: The in vitro model of experimental pellicle was saliva-coated hydroxyapatites (S-HA). Streptococcus mutans and S-HA were treated with natural medicines respectively, and then the adherence of bacteria to S-HA was tested. RESULTS: Radix et Rhizoma Rhei, Semen Arecae and Rhizoma Liguistici Chuanxiong could decrease the attachment of Streptococcus mutans to S-HA, and Semen Arecae was the most effective one. Radix Angelicae Dahuricae had no remarkable effect, and Catechu inhibited the adherence only after the bacteria being under treatment. CONCLUSION: Radix et Rhizoma Rhei, Semen Arecae, Rhizoma Liquistici Chuanxiong and Catechu could effectively inhibit the adherence of Streptococcus mutans to salivary acquired pellicle, but the effect of Radix Angelicae Dahuricae on the adherence is un-noticeable.
