对122名青少年进行了临床和唾液因素相互比较，以预测3年龋齿增量的能力。根据唾液变形链球菌和乳酸杆菌的两个水平以及基线龋齿经历（DFS）的可比水平对该组进行筛选。龋齿的风险在三个不同的水平进行了验证。计算每个水平的灵敏度、特异性以及阳性和阴性预测值。结果表明，基线龋经验是更好的或强大的唾液测试在预测未来的龋齿增量在可比的筛选和验证水平。
Clinical and salivary factors were compared with each other for the ability to predict 3-year caries increment in a group of 122 teenagers. The group was screened according to two levels of salivary mutans streptococci and lactobacilli and comparable levels of baseline caries experience (DFS). The risk for caries was validated at three different levels. Sensitivity, specificity, and the positive and negative prediction values were calculated for each level. The results showed that the baseline caries experience was better or as powerful as the salivary tests in predicting future caries increment at comparable screening and validation levels.
