九佛开展小学生口腔健康教育及窝沟封闭预防龋病和牙周病效果评价

摘要

Objective To evaluate the effects of carrying out oral cavity health study, pit and fissure sealant, defending periodontal disease and dental caries in schools. Methods 390 six-year teeth’s pit and fissure sealant students will be divided into two groups, one comparison group and two experiment groups. Due to various reasons, 78 students who lack systematical health education of oral cavity and whose parents don’t agree to make six-year teeth pit and fissure sealant operations will be the comparison group. The rest of 312 students will be automatically divided into two groups. The first group are the students who have systematical health education and meanwhile have an operation of six-year teeth pit and fissure sealant. The second group were students who just need to realize the importance of pit and fissure sealant and can’t get systematical oral cavity health education. After half a year of one year, all the students’oral cavity health knowledge, health behaviors, periodontal and dental caries’s condition will be checked. Results The results showed that the first experiment group have improved more than the first experiment group in the oral cavity health knowledge, behaviors and dental caries’s condition(P<0.05). After having an operation of pit and fissure sealant, both experiment groups don’t suffer from dental caries. Conclusion Carrying out study of oral cavity and operation of pit and fissure sealant based on schools is of great importance to defend periodontal disease and dental caries.%目的：评价在学校开展口腔健康教育及窝沟封闭预防牙周病和龋病的效果。方法将应行六龄齿窝沟封闭的390名学生进行分组，一组对照组及两组实验组。由于各种原因家长不同意实施六龄齿窝沟封闭术，也无系统的开展口腔健康教育活动的78名学生为对照组。把余下的312名学生随机分为两组实验组。实验组一为系统的开展健康教育活动及行六龄齿窝沟封闭术的学生。实验组二是只对学生及家长宣教六龄齿行窝沟封闭的重要性，单纯行六龄齿窝沟封闭术而无系统的开展口腔健康教育活动的学生。半年、一年复查口腔健康知识、健康行为、牙周健康及患龋情况。结果实施健康教育后，在口腔健康知识知晓率、行为改善率及牙周健康状况几方面，实验组一取得的效果明显高于对照组与实验组二，差异有统计学意义(P<0.05)。行六龄齿窝沟封闭术后，实验组一与实验组二复查均无患龋。结论以学校为基础开展口腔健康教育及六龄齿窝沟封闭术对预防龋病和牙周病具有重要的意义。
