目的了解平顶山市8岁学龄儿童龋病流行状况,探讨影响龋病发生发展的危险因素。方法参考"第三次全国口腔健康调查"的标准,采用分层整群抽样的方法,对1 762名适龄儿童进行口腔检查和问卷调查。结果平顶山市8岁学龄儿童患龋率84. 68%,龋均4. 79,城乡结合区域及农村儿童患龋率和龋均明显高于城市,差异有统计学意义(P<0. 05);乳、恒牙患龋率分别为83. 65%、25. 77%;城乡类型(OR=22. 42)、家庭收入(OR=10. 21)、睡前是否有吃零食习惯(OR=8. 01)、吃完零食是否刷牙(OR=6. 00)、进食甜食频率(OR=8. 28)、刷牙方法(OR=8. 88)、家长是否检查刷牙效果(OR=9. 15)是影响患龋率的因素。结论平顶山市农村及城乡结合区域儿童患龋率较高,应加强口腔健康教育和龋病预防控制工作。
Objective To investigate the prevalence of dental caries( DA) among school children aged 8 years in Pingdingshan City,and to explore the risk factors affecting the occurrence and development of DA. Methods A stratified cluster sampling method was used to select 1,762 school children aged 8 years in Pingdingshan City,and then oral examinations and questionnaire surveys were conducted according to the standard of the 3 rd Chinese National Oral Health Survey. Results The prevalence rate of dental caries in the school children aged 8 years in Pingdingshan City was 84. 68%,with an average decayed-missing-filled teeth( DMFT) of 4.79. The prevalence rates of dental caries and the average DMFT in suburban and rural children were higher than those in urban children,showing statistically significant differences( P<0.05). The prevalence rates of dental caries in the deciduous and permanent dentitions were 83.65% and 25.77% respectively. The factors contributing to dental caries included urban and rural types( OR = 22.42),family income( OR = 10.21),having a habit of snacking before going to bed( OR = 8.01),not brushing teeth after eating snacks( OR = 6.00),the frequency of eating dessert( OR = 8.28),the method of brushing teeth( OR = 8. 88)and checking the brushing effect by parents( OR = 9.15). Conclusions The prevalences rate of dental caries in rural and suburban children in Pingdingshan City are high; and hence,it is necessary to strengthen oral health education and dental caries prevention and control.
