口腔健康教育对改善中学生维护口腔健康意识的效果评价

目的评价以学校为基础的口腔健康教育改善中学生口腔健康状况的效果。方法将随机抽取的四川省德阳市农村地区2所中学的初一学生按学校分为试验组和对照组，每组200名学生。对试验组学生进行以学校为基础的口腔健康知识教育，同时要求试验组学生在家长的监督下使用含氟牙膏刷牙。对照组不采取任何干预措施。在试验前和1年后对2组学生进行龋病、口腔卫生状况检查，并对口腔健康知识、态度和行为进行问卷调查。结果1年后，与基线相比，试验组的龋均和龋面均无明显变化（P>0.05），而对照组的龋均和龋面均明显升高（P<0.05）；试验组的简化口腔卫生指数（OHI-S）下降（P<0.05），而对照组的OHI-S上升（P<0.05）；试验组学生对“使用含氟牙膏能预防蛀牙”和“甜食致龋”的认识增加率高于对照组学生（P<0.05）；试验组学生每天至少刷牙2次、使用含氟牙膏、拜访牙医的增加率高于对照组（P<0.05）。结论以学校为基础的口腔健康教育和使用含氟牙膏的综合口腔卫生项目对促进农村地区中学生口腔健康有积极的作用。
