不同材质刷毛的手动牙刷刷牙效果的临床评价

摘要

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.%目的: 比较普通尼龙丝、竹炭纤维、硅橡胶牙刷的刷牙效果.方法: 分别纳入30名和156名符合纳入标准的大专学生为研究对象,将受试者分别随机分为3组,用3种不同材质制做规定完全相同的3种牙刷按完全相同的方法刷牙1个月,检测试验前和1个月后菌斑指数(PI) (n = 10) 和试验前、1个月、3个月后的牙龈指数(GI) (n = 52) .结果: 1个月后3种牙刷全口PI清除率两两对比结果,P＞ 0. 05;在1个月后,3种牙刷的GI降低率两两比较P＞ 0. 05;在3个月后,硅橡胶软毛牙刷牙龈指数降低率高于普通尼龙丝牙刷和竹炭牙刷(P ＜ 0. 05).结论: 3种牙刷的菌斑清除效果没有差异,硅橡胶软毛牙刷对牙龈健康的促进效果优于普通牙刷和竹炭牙刷.
