The authors have studied the 8 weeks clinical examination On 32 patients of age 20s for experimental group and 34 patients of the same ages for control group, in order to find out the effect of plaque removal effect and gingival effect by use of the dentifrice contained with the Artemisiae Capillaris extract(dimethylesculetin) and NaCl. The obtained results are as followings: 1. Plaque removal effect is better at the experimental group than at the control group on 2 and 8 weeks(p<0.05). 2. There are not significantly differences on the calculus index and stain index between the experimental group and control group, during the 8 weeks experiment(p>0.05). 3. At the 8 weeks experiment, it revealed the less average scores on the PMA index for experimental group, than that of the control group(p<0.05).
