The DI-S (simplified oral debris index), CPITN (Community Periodontal Index of Treatment Needs) and dmfs (dental caries experience in the primary dentition were recorded in 395 5-year-old black children living in rural and urban areas of Southern Africa. The DI-S and CPITN were grouped, independently and together, to examine their use as simple field methods of predicting dental caries. For each grouping the sensitivity, specificity and positive and negative predictor values were calculated. A CPITN grouping of 0 or of two or more sextants with bleeding, provided the most convenient specificity, sensitivity and predictor values. It is recommended that this simple method should now be used in prospective studies of caries activity.
在居住于南部非洲城乡地区的395名5岁黑人儿童中记录了简化口腔碎屑指数（DI-S）、社区牙周治疗需求指数（CPITN）以及乳牙龋经验指数（dmfs）。DI-S和CPITN分别及共同进行分组，以检验它们作为预测龋齿的简易现场方法的用途。针对每个分组计算了敏感性、特异性以及阳性和阴性预测值。CPITN分组为0或两个及以上牙 sextant 有出血情况时，具有最便利的特异性、敏感性和预测值。建议现在应将这种简易方法用于龋齿活动的前瞻性研究。
