唾液变形链球菌测试和过去的龋齿经验被用来作为预测龋齿增量在一项为期3年的研究，包括655 12岁的学龄儿童从两个地区的饮用水中的氟化物的对比水平。在研究期间，两组的平均龋（DMFS）增量相似，但高氟地区的儿童邻面釉质病变发生率显著（P < 0.05）较高。在两组中，一方面基线时唾液变形链球菌评分和/或既往龋齿经历与另一方面研究期间龋齿增量之间存在统计学显著（P < 0.05-0.001）正相关。在低氟区和高氟区，既往患龋史是龋病风险的最强预测因子。低氟区的敏感性和特异性之和（138%）略高于高氟区（123%）。唾液细菌计数单独使用或结合过去的龋齿经验，以及过去的邻面龋的经验是不太有用的预测在这两个群体。目前的研究结果表明，天然氟暴露对龋齿风险评估和龋齿的预测能力的唾液细菌测试和过去的龋齿在低水平的疾病人群中的影响有限。
A salivary mutans streptococci test and past caries experience were used as predictors for caries increment in a 3-yr study comprising 655 12-yr-old schoolchildren from two areas with contrasting levels of fluoride in the drinking water. The mean caries (DMFS) increment was similar in both groups during the study period, but a significantly (P < 0.05) higher incidence of approximal enamel lesions was registered in children from the high fluoride area. In both groups, a statistically significant (P < 0.05-0.001) positive relationship between salivary mutans streptococci score and/or past caries experience at baseline on one hand and caries increment during the study period on the other was established. The past caries experience was the most powerful predictor of caries risk in both the low fluoride and the high fluoride area. The sum of the sensitivity and specificity was somewhat higher in the low fluoride area (138%) compared to the high fluoride area (123%). The salivary bacterial enumeration used alone or in combination with past caries experience as well as past approximal caries experience were less useful as predictors in both groups. The present findings indicate that the natural fluoride exposure has a limited influence on caries risk assessment and the caries predictive ability of the salivary bacterial test and past caries in populations with a low level of disease.
