To evaluate the effect of an oral health education programme for Chinese middle school student in the rural area to improve oral health knowledge.
The students of two middle schools in the rural area of Deyang city, Sichuan province, were randomly choosed and divided into experiment group and control group, each group 200 students. The students of experiment group were taken oral health education based on school and brushed the teeth with fluoride toothpaste under the supervision of parents. No intervention study was given to the students of control group. Before the experiment and after 1 year, the caries and oral hygiene status were examined, and the oral health knowledge, attitude and behavior were investigated by questionnaire.
There were no significant changes of DMFT and DMFS of experiment group after 1 year (P > 0.05), while the DMFT and DMFS of control group increased obviously (P < 0.05). The oral hygiene index-simplified (OHI-S) of experiment group decreased (P < 0.05), while that of control group increased (P < 0.05). The knowledge and the attitude towards "using fluoride toothpaste was a good way for preventing tooth decay" and "eating and drinking sweet things can cause tooth decay", and the behavior of "brush the teeth 2 or more times a day", "use the toothpaste containing fluoride", "visit to dentist at least once a year" in experimental group were improved compared with control group (P < 0.05).
Oral health education based on school combined the use of affordable fluoride toothpaste can improve the oral health of middle school student in the rural area.
评估一项针对中国农村中学生的口腔健康教育项目对提高口腔健康知识的效果。
随机选取四川省德阳市农村地区两所中学的学生，分为实验组和对照组，每组200名学生。对实验组学生进行学校口腔健康教育，并在家长监督下使用含氟牙膏刷牙。对照组学生不进行干预研究。实验前及1年后，检查龋病和口腔卫生状况，并通过问卷调查口腔健康知识、态度和行为。
实验组1年后DMFT和DMFS无显著变化（P>0.05），而对照组DMFT和DMFS明显增加（P<0.05）。实验组简化口腔卫生指数（OHI-S）下降（P<0.05），而对照组上升（P<0.05）。与对照组相比，实验组在“使用含氟牙膏是预防龋齿的好方法”和“饮食甜食会导致龋齿”方面的知识和态度，以及“每天刷牙2次或更多次”“使用含氟牙膏”“每年至少看一次牙医”的行为均有所改善（P<0.05）。
基于学校的口腔健康教育结合使用经济实惠的含氟牙膏可改善农村地区中学生的口腔健康。
