The aim of this study was to assess the prevalence of dental caries in the primary dentition and associated variables in low socioeconomic preschool children enrolled in public nursery schools in Juiz de Fora, Minas Gerais, Brazil. Four public institutions were selected by geographic criteria (two in the central region and two in the peripheral region). The study population comprised 338 children (181 boys; 157 girls) aged 2-6 years old. Dental caries was recorded using the decayed, missing, and filled teeth (dmf-t) index. Among the examined children, 50.6% were caries-free. The mean dmf-t index was 2.03. It was higher in the peripheral nursery schools (p<0.01). A trend towards a difference between sexes (p = 0.06) was observed. Logistic regression analysis selected a previous child's visit to dentist (p<0.001), geographic location of the public nursery school (p<0.01), and age (p<0.01) as predictive variables for the dmf-t index. The study showed the need for an oral health program for this population, including both curative and preventive measures in order to achieve the WHO/FDI goals for the year 2000, namely 50% of children free of caries at age 5-6 years.

:这项研究的目的是评估在巴西米纳斯吉拉斯州Juiz de Fora的公立托儿所就读的低社会经济学龄前儿童的龋齿患病率及其相关变量。根据地理标准选择了四个公共机构(中部地区两个,外围地区两个)。研究人群包括2至6岁的338名儿童(181名男孩; 157名女孩)。使用龋齿,缺失牙和饱牙(dmf-t)指数记录龋齿。在接受检查的儿童中,有50.6%没有龋齿。平均dmf-t指数为2.03。在外围托儿所中该比例更高(p <0.01)。观察到性别差异的趋势(p = 0.06)。 Logistic回归分析选择了以前的孩子去过牙医(p <0.001),公立幼儿园的地理位置(p <0.01)和年龄(p <0.01)作为dmf-t指数的预测变量。研究表明,需要针对这一人群制定一项口腔保健计划,包括治疗和预防措施,以实现2000年的WHO / FDI目标,即50%5-6岁无龋齿的儿童。
