ABSTRACT
Objective: To compare the effects of ordinary nylon toothbrush,bamboo fiber toothbrush and silicone rubber toothbrush. Methods: 30 and 156 college students were respectively included by the enrolment criterion and were respectively divided into 3 groups. Tooth brushes with the same specification and with the 3 materials were respectively used in the 3 goups with the same methods. Plaque index(PI) (n = 10) was examined before and 1 month after use of the brushes; gingival index(GI) was examined(n = 52) before,1 and 3 month after use of the brushes. Results: 1 month after use of the brushes full mouth PI removal rate(n = 10) and GI reduction(n = 52) were not statistically different among the 3 group(between each 2 groups,P＞ 0. 05). 3 months after use of the brushes GI reduction of the silicone rubber toothbrush group was more than that of ordinary nylon toothbrush and bamboo charcoal toothbrush groups(P ＜ 0. 05). Conclusion: Plaque removal efficiency of the 3 kinds of toothbrush is similar. The silicone rubber toothbrush is more effective for gigiva health than ordinary nylon toothbrush and bamboo charcoal toothbrush.
