摘要:

目的 调查分析重庆市城乡10~12岁儿童第一恒磨牙患龋情况并分析相关因素,为儿童龋病防治工作提供依据,并为实施有针对性的口腔健康教育提供建议。方法 2018年3—5月间,采用多阶段、分层、整群、随机抽样的方法抽取重庆市3个区及3个县共18所学校5 057名儿童进行口腔健康检查和问卷调查。结果 第一恒磨牙总患龋率为39.2%,龋失补牙数为0.84±1.20;龋齿充填率为3.4%,窝沟封闭率为6.1%。第一恒磨牙患龋率在男女之间、城乡之间、独生子女和非独生之女之间、少数民族和汉族之间的差异均有统计学意义(P<0.001),窝沟封闭率在城乡之间差异有统计学意义(P<0.001)。多因素Logistic回归分析显示:每天刷牙次数、吃甜点次数、睡前吃甜点/喝牛奶、是否独生子女、父母学历是龋病发生的独立影响因素。结论 重庆市10~12岁儿童第一恒磨牙患龋率高,窝沟封闭率及龋齿充填率较低,城乡差异较大,儿童口腔健康知识匮乏,存在不良口腔卫生行为和饮食习惯,要加强儿童口腔健康教育,将口腔健康宣教落实到学校,提高在校儿童口腔保健知识水平,缩小城乡差异。

Abstract:

Objective To investigate the caries status of the first permanent molars in urban and rural children aged 10-12 in Chongqing and analyze the related factors in order to provide a theoretical basis for the prevention and treatment of children’s caries and targeted suggestions for oral health education.Methods A multi-stage, stratified, cluster, and random sampling method was used to extract 5 057 children from 18 schools in three districts and three counties in Chongqing for oral health examination and questionnaire survey from March to May 2018.Results The total caries rate of the first permanent molar was 39.2%. The decayed-missing-filled tooth was 0.84±1.20. The rate of filling teeth was 3.4%. The rate of pit and fissure sealing was 6.1%. The prevalence of the first permanent molars was significantly different between men and women, between urban and rural areas, between only children and non-only children, and between ethnic minorities and Han nationality (P<0.001). The gap between the pit and fissure sealing was significantly different between urban and rural areas (P<0.001). Multiple logistic regression analysis showed that many independent factors influence the occurrence of caries, including the frequency of brushing teeth every day, the frequency of eating desserts, the habit of eating dessert/drinking milk before going to bed, whether only-children or not, and parents’ education background, among others.Conclusion The first permanent molars of children aged 10-12 in Chongqing have a high rate of caries but low rates of pit and fissure sealing and dental caries filling. The difference between urban and rural areas is large, children’s oral health knowledge is scarce, and children have bad oral hygiene behaviors and eating habits. Children’s oral health education must be strengthened, oral health preaching must be implemented in schools, the oral health knowledge of children in school must be improved, and urban-rural differences must be minimized.
