刷牙有效性教育对学龄儿童口腔卫生的作用

目的:探讨刷牙有效性教育对儿童口腔卫生状况的影响。方法:以经过2a有效刷牙指导的145例小学三年级学生为实验组,以未经过有效刷牙指导的147例小学三年级学生为对照组,对龋病患病率、龋均、牙龈炎指数(GI)、简化口腔卫生指数(OHI-s)进行比较。患龋率用χ2检验,GI、OHI-s指数用t检验做统计学分析。结果:实验组刷牙教育后患龋率、龋均、牙龈指数、简化口腔卫生指数均低于对照组,差异显著(P<0.01)。结论:刷牙有效性教育对改善儿童口腔卫生状况有显著作用。

The effect of teeth brushing education on oral health of school children

PURPOSE: To investigate the state of oral health of children after education of teeth-brushing. METHODS: The experimental group included 145 pupils in school after education of teeth-brushing for two years. The control group included the 147 pupils in school without education of teeth-brushing. The prevalence rate of dental caries, caries average, the gingival index and the oral hygiene index-simplified were examined and statistically analyzed by chi(2) test and student's t test. RESULTS: The indexes of the prevalence rate of dental caries, caries average, GI, OHI-s in the experimental group after teeth brushing education were better than in the control group (P<0.01). CONCLUSION: The education of teeth-brushing improves the oral health of children significantly.
