摘要：

目的 比较广州市城、郊幼儿患龋差异并分析影响差异的因素。方法 2005年，中山大学附属口腔医院预防科采用随机整群抽样方法，抽取广州市东山区5所幼儿园和郊区从化市（县级市）7所幼儿园所有小班日托幼儿，对其口腔健康状况进行调查，共调查3 ~ 4岁幼儿729人，其中广州360人（男186人，女174人），从化369人（男212人，女157人），平均年龄3.64岁。调查内容包括龋病和釉质发育缺陷的患病状况及可见菌斑指数。并对其父母进行问卷调查，收集与患龋有关信息。结果 广州市城区幼儿龋均1.01，龋患率29.4%;郊区幼儿龋均3.70，龋患率68.0%;两地龋均及患龋率差异有统计学意义（P < 0.01）。多重回归分析显示，10种因素与所调查幼儿患龋相关，其中5种因素在城郊幼儿之间差异有统计学意义（P < 0.05），包括晚间吃甜食、3岁后使用牙膏、母亲年龄、父母口腔健康态度和家庭收入。结论 影响广州市郊区幼儿患龋显著高于城区的相关因素是儿童晚间吃甜食、3岁后才开始使用牙膏、母亲年龄较轻、父母口腔健康态度不够积极和家庭收入较低。

ZHANG Rong*， LIN Huan-cai， ZHI Qing-hui. *Department of Stomatology， Peking University Shougang Hospital， Beijing 100041，ChinaAbstract： Objective To compare the prevalence of caries in deciduous teeth of children from urban and suburban areas of Guangzhou and analyse the related factors. Methods Five nursery schools in Dongshan District of Guangzhou and 7 nursery schools in Conghua were chosesn randomly in 2005. Dental caries status， developmental defect of enamel （DDE） and Visible Plaque Index （VPI） of 3-4-year-old children were recorded. Data of caries related information were collected by structured questionnaire completed by their parents. Results The dmft and prevalence of caries of children in Guangzhou and Conghua were significantly different （1.01 v.s. 3.70 and 29.4% v.s. 68.0% respectively， P < 0.01）. The results of multiple regression found 10 factors related to the dmft level of the children investigated. Comparison between the two groups showed that 5 in the 10 factors were significantly different， including consuming sweet at night， using toothpaste after 3 years old， mothers’ age， parents’ oral health attitude and income. Conclusion The results of this cross-section survey primarily suggests that the reasons related to the high dmft level of the children in suburban areas of Guangzhou are consuming sweet at night， using toothpaste after 3 years old， mothers’ age being younger， parents’ oral health attitude being not active and lower income.
