The value of defined levels of oral hygiene and dietary habits for predicting caries was investigated. The material comprised 143 3-yr-olds. Three levels of oral hygiene and dietary habits, respectively, were used. Oral hygiene was registered as gingival status. Dietary habits were recorded by interview. Two groups were then formed by pooling stepwise the caries data for the nine possible combinations of oral hygiene and dietary habits and setting the most discriminating border, screening level, where the properties sensitivity and specificity simultaneously reached their highest value. Children with clean teeth, irrespective of dietary habits, and children with suitable dietary habits, provided they did not have general gingivitis with bleeding, might be regarded as no caries risks, while children with other combinations of oral hygiene and dietary habits were caries risks. The difference in decayed surfaces between the two groups was statistically significant (p less than 0.001). The sensitivity was 0.89 and the specificity 0.70. The predictive value of a negative test (0.91) was higher than that of a positive test (0.64).
研究了特定口腔卫生水平和饮食习惯对龋齿预测的价值。研究材料包括143名3岁儿童。分别采用了三种口腔卫生水平和饮食习惯水平。口腔卫生状况以牙龈状态记录。饮食习惯通过访谈记录。然后通过逐步汇总口腔卫生和饮食习惯九种可能组合的龋齿数据，并设定最具区分性的边界（筛查水平），即敏感性和特异性同时达到最高值的水平，将儿童分为两组。牙齿清洁的儿童，无论饮食习惯如何；以及饮食习惯适宜且无牙龈普遍出血性炎症的儿童，可视为无龋齿风险，而口腔卫生和饮食习惯为其他组合的儿童则有龋齿风险。两组之间龋面差异具有统计学意义（p<0.001）。敏感性为0.89，特异性为0.70。阴性检测的预测值（0.91）高于阳性检测的预测值（0.64）。
