摘　　要：目的 观察牙龈健康者和牙龈炎患者使用电动牙刷去除菌斑的作用。方法 选择年龄18～25岁医学院学生共50名,检查菌斑指数后使用声波震动牙刷每天刷牙2次,每次2min。连续使用2周和1个月后分别检查菌斑指数。对检查结果进行统计分析。结果 无论是牙龈健康组还是牙龈炎组,刷牙后与刷牙前比较菌斑指数均明显下降,统计学分析具高度显著性差异,连续刷牙1个月后与1个月前比较菌斑指数在刷牙前就有所下降,统计学分析具高度显著性差异。结论 声波震动牙刷能有效清除牙菌斑。Objective To observe the clinical effect of Sonicare on removing plaque by introducing Sonicare to both health and gingivitis subjects. Methods 50 medical students, aged between 18 and 25 years old, were chosen. The baseline Plaque Index (PI) is recorded then Philips Sonicare electric toothbrushes were provided to be used 2 times a day and 2 minutes each time. After two-week and one-month period of continuous using Sonicare, the PI was evaluated and the data wsa analysed with wilcoxon rank test and kruskal-wallis rank test. Results The PI decreased signficantly in both groups, and the difference is significant statisti- cally. After one month period of continuous using Sonicare, the PI decreased as compared to the baseline statistically. Conclusion Sonicare can remove debries effectively.
