The level of Streptococcus mutans in saliva was determined by a dip-slide method in 841 13-year-old children in order to identify children with high caries risk. For each child, the flow rate of saliva was determined. Caries scores were obtained from Public Dental Health records. A sucrose intake score was calculated based on self-reported frequency of intake of six types of sugary products. As S. mutans counts increased, there was a significant trend of increased DMFS and DS scores. No linear correlation was observed between reported intake of sucrose and S. mutans counts, but the children with the highest counts (class 3) tended to have significantly higher sucrose intake than the rest of the children. The flow rate of saliva decreased significantly as S. mutans increased.
为了确定高龋齿风险儿童，采用浸片法对841名13岁儿童的唾液变形链球菌水平进行了测定。对每个儿童测定唾液流速。龋齿评分来自公共牙科健康记录。根据自我报告的六种含糖产品摄入频率计算蔗糖摄入评分。随着变形链球菌计数增加，龋失补牙面数（DMFS）和龋失补牙数（DS）评分有显著增加趋势。报告的蔗糖摄入量与变形链球菌计数之间未观察到线性相关性，但计数最高的儿童（3级）的蔗糖摄入量往往显著高于其他儿童。随着变形链球菌增加，唾液流速显著降低。
