摘　　要：目的了解广州市白云区城乡结合部7~8岁儿童乳磨牙龋病和恒牙萌出情况并探讨其与生长发育的关系,为合理开展乳牙龋病防治提供理论依据。方法采用横断面研究方法,随机抽取广州市白云区城乡结合部11所小学7~8岁儿童1 543名作为研究对象,进行口腔检查,记录乳磨牙龋病和恒牙萌出情况,测量身高体重,并计算体质量指数(Body Mass Index,BMI)(kg/m2),按国际肥胖委员会(IOTF)标准分为消瘦、正常、超重和肥胖四组。以Logistic回归分析是否超重/肥胖与患龋和恒牙萌出的相关性。结果调查的7~8岁儿童,乳磨牙患龋率为80.0%,龋均为3.45±2.72,恒牙萌出均数为10.57±2.12。随体质量指数升高,乳磨牙龋齿数量降低,恒牙萌出数增高。结论乳磨牙龋病和恒牙萌出与生长发育关系密切。Objective To learn about the prevalence of primary molars and permanent teeth eruption, then to determine the relationship between them and the body mass index among 7 and 8 years old school children in the rural-urban continuum of Baiyun District of Guangzhou City, China. Methods This cress-sectional study enrolled 1543 pupils aged 7and 8 years from 11 elementary schools in Baiyun District of Guangzhou in order to conduct oral examination, record information about primary molars caries and teeth eruption. Height and weight were measured and BMI estimated in kg/m2. Children were classified into underweight, normal weight, overweight and obesity groups by BMI based on IOTF standards. Whether there is a certain relation between overweight/obesity and primary molars caries or permanent teeth eruption was tested using logistic regression. Results The prevalence of primary dental caries was 80.0% whereas dmft and the mean of erupted permanent teeth were 3.42±2.72 and 10.57±2.12 respectively. With the increase of BMI, the prevalence in primary molars caries tended to decline while the number of erupted permanent teeth showed a similar upward trend. Conclusion BMI is closely related to primary molars caries and permanent teeth eruption.
