儿童使用声波震动牙刷清除牙菌斑的效果观察

目的:观察儿童使用声波震动牙刷清洁牙及控制菌斑的效果。方法:选择年龄6～7岁的儿童50例,实验组使用声波震动牙刷,对照组使用儿童保健牙刷。采用菌斑染色法记录刷牙前后的菌斑牙面数及菌斑指数(PLI),采用SPSS10.0统计软件包对相关组间数据进行t检验与χ2检验。结果:实验组菌斑清除率为70.22%,对照组为39.08%,声波震动牙刷去除舌面、近中颊面菌斑的能力是手动刷牙的2倍。刷牙前后菌斑指数和菌斑清除率在2组间有高度显著性差异(P<0.001)。结论:声波震动牙刷能有效帮助儿童清除牙面菌斑,是儿童口腔护理的有效工具。

The efficacy of dental plaque removed by using sonic electric toothbrush in children

PURPOSE: To evaluate the efficacy of using sonic electric toothbrush to clean the teeth and control dental plaque in children. METHODS: 50 children aged 6 to 7 years old were selected and divided into 2 groups according to the use of sonic electric toothbrush and traditional manual toothbrush (control group). The numbers of dental plaque surface and PLI before and after tooth brushing were recorded. The data of the two groups were analyzed with SPSS10.0 software package for student's t test and chi(2) test. RESULTS: The ratio of dental plaque removal was 70.22% by using sonic electric toothbrush and 39.08% in the control group. The efficacy of dental plaque removal on the lingual and mesial buccal surface by using sonic electric toothbrush was 2 times greater than the control group. The PLI and the ratio of dental plaque removal were significantly different between the 2 groups (P<0.001). CONCLUSIONS: Sonic electric toothbrush can help children effectively remove dental plaque. It's an efficient instrument for oral care of children.
