A cross-sectional study of dental caries in the primary teeth as a function of nutritional status was conducted on 1481 children one to 13 years old in Lima, Perú. Forty-one percent of the children were found to be chronically malnourished (stunted), 3% were acutely malnourished (wasted), and 5% were both stunted and wasted. A plot of decayed, extracted, and filled teeth (deft) vs. age resulted in a bell-shaped curve that was shifted to the right by 2.5 years for malnourished groups, compared with normal children (p less than 0.01). The shift to the right of the age distribution of caries was associated with a delay in both the eruption and exfoliation of the primary teeth in malnourished children. Peak caries activity was significantly higher in wasted and in stunted and wasted children, when compared with normal controls. It is concluded that malnutrition delayed tooth development, affected the age distribution of dental caries, and resulted in increased caries experience in the primary teeth.
在秘鲁利马，对1481名1至13岁儿童进行了一项关于乳牙龋齿与营养状况关系的横断面研究。结果发现，41%的儿童长期营养不良（发育迟缓），3%的儿童急性营养不良（消瘦），5%的儿童既发育迟缓又消瘦。绘制龋齿、拔牙和补牙（deft）与年龄的关系图，结果显示为钟形曲线，与正常儿童相比，营养不良组的曲线向右偏移了2.5年（p小于0.01）。龋齿年龄分布向右偏移与营养不良儿童乳牙萌出和脱落延迟有关。与正常对照组相比，消瘦儿童以及既发育迟缓又消瘦的儿童的龋齿活动高峰期明显更高。研究得出结论，营养不良会延迟牙齿发育，影响龋齿的年龄分布，并导致乳牙龋齿发生率增加。
