重庆市12岁儿童恒牙龋患率及影响因素分析

Analysis on caries prevalence of permanent teeth and its influencing factors among 12-years-old children in Chongqing

目的了解重庆市12岁儿童恒牙龋患率及影响因素,为进一步加强儿童口腔疾病综合防治工作提供建议。方法2015年4—6月采取分层整群抽样的方法调查在校12岁儿童口腔健康行为与健康状况,恒牙龋患率及影响因素情况采用χ2检验与逐步后退法的多因素Logistic回归进行分析,P〈0.05为差异有统计学意义。结果共调查12岁儿童4 346人,恒牙龋患率为29.84%（1 297/4 346）,龋均为0.77。多因素Logistic回归分析显示,地区（OR=3.51,95%CI为3.02~4.07）,性别（OR=1.31,95%CI为1.14~1.51）,平时进食糖果、巧克力的频率（OR=1.20,95%CI为1.09~1.33）,在睡前吃甜点或（和）甜饮料的频率（OR=0.88,95%CI为0.78~0.99）,自我口腔健康状况评价（OR=1.31,95%CI为1.20~1.42）,牙龈出血（OR=2.79,95%CI为2.26~3.44）,窝沟封闭项目（OR=0.70,95%CI为0.61~0.80）是儿童恒牙患龋的独立影响因素。结论重庆市12岁儿童恒牙龋患率高,窝沟封闭项目可以有效地预防龋患,应大力推广应用。

Objective To understand caries prevalence of permanent teeth and its influencing factors among 12-yearsold children,and to provide the suggestion for strengthening the comprehensive intervention for oral health among children further. Methods 12-years-old children in school were sampled by stratified cluster sampling to investigate their oral health behavior and health status from April to June 2015. The influencing factors of caries prevalence of permanent teeth were identified by Chi-square test and multi-variant Logistic regression,P〈0.05 was considered statistically significant. Results A total of 4 346 children aged 12 years old were investigated. The caries prevalence of permanent teeth was 29.84%. DMFT of permanent teeth was 0.77. The results of multivariant Logistic regression analysis indicated that factors such as area（OR=3.51,95%CI 3.02-4.07）, gender（OR=1.31, 95%CI 1.14-1.51）, the frequency of eating sugar or chocolate（OR=1.20,95%CI 1.09-1.33）, the frequency of eating sweet dessert and beverage before sleeping（OR=0.88, 95%CI 0.78-0.99）, self-evaluation of oral health（OR=1.31, 95%CI 1.20-1.42）, gingival bleeding（OR=2.79, 95%CI 2.26-3.44） and fissure sealing program（OR=0.70, 95%CI 0.61-0.80） were independent factors of caries of permanent teeth.Conclusion The caries prevalence of permanent teeth among 12-years-old children was high. The program of fissure sealing is effective for caries prevention. This program should be promoted extensively.
