The association between caries prevalence and clinical (presence of visible plaque in the labial surfaces of maxillary incisors), microbiological (salivary levels of mutans streptococci) and dietary variables was evaluated in 142 1.0- to 2.5-year-old children attending public day-care nurseries in the city of Piracicaba - São Paulo. A significant difference in caries prevalence was observed between those children with and without visible plaque (chi2 = 12.08, p < 0.001). The mean ds (decayed surfaces) was significantly higher in children with visible plaque on the maxillary incisors than in children without it (p < 0.001). Mutans streptococci were detected in 114 (80.3%) of the children. A significantly higher caries prevalence was observed in children with high levels of mutans streptococci compared to children with low levels (chi2 = 28.67, p < 0.001). The mean ds was significantly higher in children with levels of mutans streptococci greater than 50 CFU when compared to children with 0 CFU or 1-50 CFU of mutans streptococci (p < 0.05). Children who were either never breast-fed or only until 3 months exhibited a significantly higher caries prevalence than those breast-fed for a longer time (chi2 = 4.11, p < 0.05). A significantly higher caries prevalence was also observed between children that used bottle containing milk with sucrose and cereal than children using bottle with milk with or without sucrose (chi2 = 6.24, p < 0.05). Children who started to eat salty meals at or after 7 months of age showed a significant higher caries prevalence than children who started earlier (chi2 = 10.30, p < 0.01). These data support the evidence of an association between caries prevalence in young children and mutans streptococci levels, clinical and dietary factors.
在巴西圣保罗州皮拉西卡巴市公立日托托儿所的142名1.0至2.5岁儿童中，评估了龋齿患病率与临床因素（上颌中切牙唇面可见牙菌斑的存在情况）、微生物因素（变形链球菌的唾液水平）和饮食变量之间的关联。观察到有可见牙菌斑和无可见牙菌斑的儿童在龋齿患病率上存在显著差异（卡方值=12.08，p<0.001）。上颌中切牙有可见牙菌斑的儿童的平均龋面数（ds）显著高于无可见牙菌斑的儿童（p<0.001）。在114名（80.3%）儿童中检测到变形链球菌。与变形链球菌水平低的儿童相比，变形链球菌水平高的儿童的龋齿患病率显著更高（卡方值=28.67，p<0.001）。与变形链球菌水平为0 CFU或1 - 50 CFU的儿童相比，变形链球菌水平大于50 CFU的儿童的平均ds显著更高（p<0.05）。从未母乳喂养或仅母乳喂养至3个月的儿童的龋齿患病率显著高于母乳喂养时间更长的儿童（卡方值=4.11，p<0.05）。与使用含或不含蔗糖牛奶奶瓶的儿童相比，使用含蔗糖和谷物牛奶奶瓶的儿童的龋齿患病率也显著更高（卡方值=6.24，p<0.05）。7个月及以后开始吃咸味食物的儿童的龋齿患病率显著高于更早开始吃咸味食物的儿童（卡方值=10.30，p<0.01）。这些数据支持了幼儿龋齿患病率与变形链球菌水平、临床和饮食因素之间存在关联的证据。
