Effect of health education on oral hygiene status in secondary school students

目的调查中学生的口腔卫生习惯;评价口腔健康宣教对改善中学生口腔卫生状况的效果。方法抽取某中等专科学校160名学生,发放调查问卷调查中学生的刷牙行为及影响口腔卫生状况的相关因素;将160名学生分为实验组和对照组。对实验组学生进行口腔健康宣教,对照组不做任何干预措施。3月后,评价两组学生的口腔卫生状况改善情况。结果实验组学生的简化牙石指数(calculus index-simplified,CI-S)、菌斑指数(plaque index,PLI)和牙龈指数(gingival index,GI)与对照组相比有明显改善(P<0.05)。刷牙行为和饮食习惯与中学生的口腔卫生状况关系密切,而家庭环境、来源地对中学生口腔卫生状况无影响。结论通过口腔健康宣教进行干预,可有效改善中学生口腔卫生状况。

Objective To investigate the oral hygiene habits of the students and evaluate the effects of oral health education on improving the oral hygiene status of the school students. Methods One hundred and sixty students of a technical secondary school were selected. Survey on tooth-brushing behaviors and related factors in oral health status of the school students was conducted by questionnaire. Students of the school were divided into experimental and control groups. Students in the experimental group were given oral health education, while control group without any intervention. After 3 months, oral hygiene status of the two group students was evaluated. Results Three months later, compared with the control group, calculus indexsimplified （CI-S）, plaque index （PLI） and gingival index （GI） were all significantly improved in the experimental group （ P 〈 0. 05 ）. Tooth-brushing behavior and diet habits were closely related to the oral hygiene status of the secondary school students, while the family environment and homeplace had no significant differences in the oral hygiene status of secondary school students. Conclusion Intervention through oral health education can effectively im- prove the oral health status of secondary school students.
