目的探讨廊坊市6~12岁儿童恒牙窝沟封闭状况,为提高儿童窝沟封闭率提供科学依据。方法随机选取2014年3-6月廊坊市区4所小学的6~12岁儿童2 560名进行口腔检查,发放针对家长的调查问卷并回收。结果 6~12周岁儿童恒牙窝沟封闭率为1.39%~13.06%,呈现随年龄增加而升高的趋势,人均封闭牙数为0.04~0.22。男性窝沟封闭率(11.17%)高于女性(4.61%),差异有统计学意义(χ2=11.07,P<0.01)。结论窝沟封闭是预防龋病的有效方法。廊坊市6~12岁儿童窝沟封闭率处于较低水平,家长对窝沟封闭的认知度偏低。
Objective To investigate the occlusion status of permanent dentition and fissure in children aged 6 ~ 12 years old in Langfang, and to provide a scientific basis for improving the fissure sealability in children. Methods A total of 2 560 children from 6 to 12 years old from 4 primary schools in Langfang City from March to June 2014 were selected for oral examination and questionnaires for parents were distributed and collected. Results The occlusion rate of permanent dentition and fissure in children aged 6 ~ 12 years was 1.39% ~ 13.06%, showing a tendency of increasing with age, the number of closed teeth per capita was 0.04 ~ 0.22. The sealing rate of male pit and fissure (11.17%) was higher than that of female (4.61%), the difference was statistically significant (χ2 = 11.07, P <0.01). Conclusion Pit and fissure sealant is an effective way to prevent dental caries.
