The prevalence of dental caries and gingivitis was assessed in schoolchildren of the Tlalpan region in Mexico City. A total of 700 children (age range: 11-17 yr) of both sexes were examined. The sample population included children attending the Middle-School System, where two shifts are run (A.M. and P.M.). Decayed, missing and filled surfaces (DMFS), and Gingival Index (GI) were recorded for all existing teeth. Analysis of the data showed that mean DMFS scores increased with chronological age in both genders, were higher in the P.M. session, and more elevated in females. Similarly the mean GI scores also increased with age, and were higher in the P.M. session. In contrast to the DMFS scores, males presented higher GI scores than females at all age intervals. The results of our study indicated a distinctively high prevalence of caries and gingivitis in Mexican schoolchildren.
对墨西哥城特拉尔潘地区的学童进行了龋齿和牙龈炎患病率评估。共检查了700名儿童（年龄范围：11至17岁），男女皆有。样本群体包括就读于中学系统的儿童，该系统有两个班次（上午和下午）。记录了所有现存牙齿的龋失补牙面数（DMFS）和牙龈指数（GI）。数据分析表明，男女的平均DMFS评分均随实足年龄增加，下午班次的评分更高，女性的评分更高。同样，平均GI评分也随年龄增加，下午班次的评分更高。与DMFS评分相反，在所有年龄区间，男性的GI评分均高于女性。我们的研究结果表明，墨西哥学童的龋齿和牙龈炎患病率显著较高。
