The influence of strengthening education and toothbrushing on oral health in preschool children

目的研究口腔卫生宣教和强化刷牙对学龄前儿童口腔卫生的影响。方法以全口牙平均菌斑指数(PLI)为指标,比较实验组和对照组的强化卫生宣教和强化刷牙前后儿童口腔菌斑指数的变化。结果半年后的检查结果对照组平均菌斑指数为3.14±0.53,实验组为2.71±0.56,两者差异显著(P=0.012);实验组在强化卫生宣教和强化刷牙前后全口平均菌斑指数分别为3.23±0.51和2.71±0.56,两者有显著性差异(P=0.002)。结论口腔卫生宣教和强化刷牙有助于提高儿童的口腔卫生。

Objective To study the influence of strengthening education and toothbrushing on oral health in preschool children.Methods We used full-mouth mean dental plaque index（PLI） as an indicator,observed PLI changes in the experimental group and control group before and after strengthening health education and toothbrushing.Results After six months,the mean plaque index was 3.14 ± 0.53 for control group,2.71 ± 0.56 for experimental group,the difference was statistically significant（P=0.012）;In the experimental group,the mean plaque index was 3.23 ± 0.51 before and 2.71 ± 0.56 after strengthening health education and toothbrushing,the difference was statistically significant（P =0.002）.Conclusion Strengthening oral health education and toothbrushing can improve the oral health of preschool children.
