To analyse the caries experience in preschool children at two moments 10 years apart.
Two cross-sectional epidemiological studies, the first in 2006 (n = 275) and the second in 2016 (n = 258), were carried out with samples composed of children from 3 to 6 years of age. All children were enrolled in the municipal schools of basic education of a municipality in northwest São Paulo state, and they attended an annual and continuous oral health education programme. Caries experience was calculated for deciduous and permanent teeth using the dmft and DMFT indices, according to the World Health Organization (WHO). Statistical analysis was performed using Epi info 7.1 and Bioestat 5.0 software.
In 2006, the mean dmft index was 1.88, with 7.59% of teeth having caries experience. In 2016, the mean dmft index was 0.99, with 5.15% of teeth showing caries experience. In contrast, in 2006, the mean DMFT index was 0.08 (n = 509), with 4.1% of teeth with caries experience; in 2016, the mean DMFT index was 0.06 (n = 381) and 3.6% of teeth showed caries experience. The proportions of teeth with caries experience differed statistically significantly (p = 0.435). In the last study, 78.2% of the children were caries free, below the WHO target for 2020. The Significant Caries Index (SiC Index) was 0.2.
A decline of caries experience in the deciduous dentition was found in the study population.
分析间隔10年的两个时间点学龄前儿童的龋病患病情况。
开展了两项横断面流行病学研究，第一项于2006年进行（n = 275），第二项于2016年进行（n = 258），样本由3至6岁的儿童组成。所有儿童均就读于圣保罗州西北部一个市的市立基础教育学校，并参加了年度持续口腔健康教育项目。根据世界卫生组织（WHO）的标准，使用dmft和DMFT指数计算乳牙和恒牙的龋病患病情况。使用Epi info 7.1和Bioestat 5.0软件进行统计分析。
2006年，平均dmft指数为1.88，7.59%的牙齿有龋病患病情况。2016年，平均dmft指数为0.99，5.15%的牙齿有龋病患病情况。相比之下，2006年，平均DMFT指数为0.08（n = 509），4.1%的牙齿有龋病患病情况；2016年，平均DMFT指数为0.06（n = 381），3.6%的牙齿有龋病患病情况。有龋病患病情况的牙齿比例在统计学上有显著差异（p = 0.435）。在最后一项研究中，78.2%的儿童无龋，低于WHO 2020年的目标。龋均指数（SiC指数）为0.2。
在研究人群中发现乳牙列的龋病患病情况有所下降。
