This study describes dental caries data and fluorosis in seven municipalities in the Sorocaba region, S o Paulo State, Brazil, comparing those with fluoridated as opposed to non-fluoridated water. Criteria were those proposed by the World Health Organization (WHO, 1997), adapted by the School of Public Health, University of S o Paulo. The sample was selected at random, without replacement, and was calculated by age, accepting a design error of 2 and a sampling loss of 20% (n = 96 per age). There were six trained examiners, with accepted agreement percentage above 89% for all variables. In the Sorocaba region, the dmft index in 5 year-old children was 3.1, and 37.6% were caries-free (DMFT = 0). At age 12, 32.3% were caries-free (DMFT = 0), and the DMFT index in the region was 2.6, thus characterizing the area as having a low prevalence of caries. In areas with fluoridated water, the proportion of caries-free children at 12 years was higher than in those without fluoridated water (p = 0.019), and the DMFT was lower (p = 0.001). Prevalence of fluorosis at age 12 was 12.7% in the Sorocaba area and did not pose a public health problem according to the community fluorosis index (CFI).
本研究描述了巴西圣保罗州索罗卡巴地区七个市的龋齿数据和氟牙症情况，比较了饮用含氟水和不含氟水地区的差异。标准采用世界卫生组织（WHO，1997年）提出、圣保罗大学公共卫生学院修订的标准。样本随机抽取且无放回，按年龄计算，允许设计误差为2%，抽样损失为20%（每个年龄段n = 96）。有六名经过培训的检查人员，所有变量的接受一致性百分比均高于89%。在索罗卡巴地区，5岁儿童的dmft指数为3.1，37.6%无龋齿（DMFT = 0）。12岁时，32.3%无龋齿（DMFT = 0），该地区的DMFT指数为2.6，因此该地区龋齿患病率较低。在饮用含氟水的地区，12岁无龋齿儿童的比例高于未饮用含氟水的地区（p = 0.019），且DMFT较低（p = 0.001）。根据社区氟牙症指数（CFI），索罗卡巴地区12岁儿童的氟牙症患病率为12.7%，未构成公共卫生问题。
