A cross-sectional evaluation of dental caries in primary teeth and nutritional status was conducted involving 285 Peruvian children from low socioeconomic conditions aged 3-9 y. Forty-nine percent of the children were found to be chronically malnourished (stunted) whereas acute malnutrition (wasting) was infrequent (2%). Stunted children showed a delayed exfoliation of primary teeth. The caries prevalence curve as a function of age (ie, a plot of decayed, extracted, and filled teeth vs age) was found to be shifted to the right by approximately 15 mo in stunted children as compared with well-nourished children. Children aged 7-9 y with stunted growth showed a significantly higher percentage of carious teeth than did well-nourished children of the same age (40 and 29%, respectively; p less than 0.005). Nutritional deficits that lead to chronic malnutrition not only may affect tooth exfoliation but also appear to render the primary teeth more susceptible to caries attack later in life.
对285名来自秘鲁社会经济条件较差的3至9岁儿童进行了乳牙龋齿和营养状况的横断面评估。发现49%的儿童长期营养不良（发育迟缓），而急性营养不良（消瘦）情况较少见（2%）。发育迟缓的儿童乳牙脱落延迟。与营养良好的儿童相比，发育迟缓儿童的龋齿患病率曲线（即龋、失、补牙数与年龄的关系图）向右偏移约15个月。7至9岁生长发育迟缓的儿童龋齿发生率明显高于同年龄营养良好的儿童（分别为40%和29%；p<0.005）。导致慢性营养不良的营养缺乏不仅可能影响牙齿脱落，而且似乎使乳牙在以后的生活中更容易受到龋齿的侵袭。
