Abstract: Objective To investigate the correlation research of the level of children's physical growth and deciduous teeth caries and provide the basis for making precautionary measures. Method From April to June in 2013, 1 157 children of Weibin district Xinxiang city who born in 2007 were selected, measured height and weight and calculate body mass index (BMI), evaluation BMI by five hierarchy method in deviation method, meanwhile, making oral examination for all of the children was analyzed the correlation of BMI and deciduous teeth caries. Results The dental caries rate had a trend of gradual decrease with increase of BMI, the differences between dental caries rate of each groups was statistically significant (P=0.004).The average BMI of dental caries group was below than healthy mouth group in boys and girls (P=0.001, P=0.017). Conclusion Nutriture and caries influence each other, and comprehensive measures for preventing should be adopted.

摘要： 目的 探讨儿童体格生长水平与乳牙龋病的相关性, 为制定预防措施提供依据。方法 2013年4-6月, 选取新乡市卫滨区2007年出生的全体儿童, 共1 157人, 测量身高和体重, 计算体质指数(body mass index, BMI)值, 采用离差法中的五等级划分法评价所测BMI水平, 同时全部进行口腔检查, 分析体质指数与龋病之间的相关性。结果 患龋率随着BMI的增高有逐渐降低的趋势, 各组患龋率差异有统计学意义(P=0.004)。男童和女童的患龋组BMI均值均低于未患龋组(P值分别为0.001、0.017)。结论 营养状况与龋病相互影响, 应采取综合措施预防。
