摘要

目的:研究东莞市城乡12岁儿童恒牙龋病现状及其行为影响因素,分析两者之间的关系,为东莞市儿童口腔卫生保健工作提供科学依据.方法:采用多阶段、分层、整群、随机抽样的方法,抽取东莞市12岁城乡常住人口604人,检查全口恒牙龋病的患病状况并用问卷调查的方式收集全部受检儿童口腔健康行为等相关因素.结果:东莞市12岁儿童患龋率和龋均分别是40.89％和1.47.Logistic回归分析显示:口腔保健知识掌握越多的儿童其患龋率越低,食用水果的频率越高,儿童患龋率也相应增加.结论:东莞市12岁儿童患龋水平较高,口腔卫生行为较差,口腔保健知识掌握情况是致龋最为重要的影响因素,食用水果的频率是危险因素.%AIM; To investigate the relationships between dental caries and behavioral risk factors amongrn12-year-old children in Dongguan City. METHODS; The survey employed a multistage,stratified,clustered, randomized sampling method. Six hundred and four 12 - year - old children of urban and rural residency in DongGuan were enrolled to investigate the prevalence of dental caries. Oral health behavior and other relevant factors were collected by questionnaire survey. RESULTS: The incidence of caries and mean DMFT in 12-year-old children in DongGuan were 40.89% and 1.47 respectively. Logistic regression analysis showed that a negative correlation existed between oral health knowledge and the incidence of caries, and a positive correlation existed between the intake frequency of fruits and the incidence of caries among the children. CONCLUSION; The incidence of caries was high and oral health behaviour was poor among 12-year-old children in DongGuan city. Oral health knowledge was the most important influencing factor of dental caries. Fruit intake was also a risk factor of dental caries.
