The aim of the study was to evaluate the relationship between the Body Mass Index (BMI) and the DMFT index, in 207 adolescents aged 12 years old, from 8 public and private schools of the central west area of São Paulo State. From a sample of 380 12 year-old adolescents, both genders, 207 were examined. We used the index DMFT, CBI for weight, measured of stature and applied a questionnaire about alimentary habits, characteristic anthropometrics and physical activity. Regarding body weight, 55.93% was normal, 35.59% had low weight, and 8.47% were pre-obese in private schools. In the public schools, 52.03% had normal weight, 41.22% had low weight, 4.73% were pre-obese and 2.03% were obese, without significant difference (p=0.45). The DMFT of public schools was 2.16, compared to 0.23 in private schools (p<0.05), with 39.2% of caries-free individuals in public schools and 88.1% in private schools. There was no correlation between the increase in BMI and the increase in DMFT. There was negative correlation between socioeconomic conditions and dental caries. It was concluded that, even though the pre-obese and obese groups presented a higher frequency of food ingestion, obesity was not correlated with the increase in dental caries. However, the socioeconomic conditions were determinant for this occurrence.
本研究旨在评估圣保罗州中西部地区8所公立和私立学校的207名12岁青少年的体重指数（BMI）与恒牙龋失补牙数（DMFT）指数之间的关系。在380名12岁青少年（男女均有）的样本中，对207名进行了检查。我们使用了DMFT指数、体重的体质指数（CBI）、测量身高，并应用了一份关于饮食习惯、人体测量特征和身体活动的问卷。关于体重，私立学校中55.93%正常，35.59%体重过轻，8.47%处于肥胖前期。在公立学校中，52.03%体重正常，41.22%体重过轻，4.73%处于肥胖前期，2.03%肥胖，无显著差异（p = 0.45）。公立学校的DMFT为2.16，而私立学校为0.23（p<0.05），公立学校无龋个体占39.2%，私立学校占88.1%。BMI的增加与DMFT的增加之间没有相关性。社会经济状况与龋齿之间存在负相关。得出的结论是，尽管肥胖前期和肥胖组的食物摄入频率较高，但肥胖与龋齿的增加无关。然而，社会经济状况是这种情况的决定因素。
