In a prospective longitudinal study, 1099 first grade children from Aiken, South Carolina, and 1086 children from Portland, Maine, were examined annually for 3 years. Caries prevalence and dmfs incidence were determined. The mean dmfs in Portland children was 2.9. In Aiken, white children had a mean dmfs of 8.4, and black children had a mean dmfs of 10.2. The mean 3-year primary tooth caries increment was 1.5 surfaces in the Portland cohort 3.3 surfaces in the Aiken white cohort and 2.8 surfaces in the Aiken black cohort. These increments were divided evenly between interproximal and fissure surfaces. Twenty percent of the children in Portland had 75% of the caries; in Aiken, 20% of the children had 60% of the caries. This distribution suggests a high-risk group that could be targeted for aggressive caries prevention efforts if risk factors can be identified.
在一项前瞻性纵向研究中，对来自南卡罗来纳州艾肯市的1099名一年级儿童和缅因州波特兰市的1086名儿童进行了为期3年的年度检查。确定了龋齿患病率和乳牙龋失补牙面数（dmfs）发病率。波特兰儿童的平均dmfs为2.9。在艾肯市，白人儿童的平均dmfs为8.4，黑人儿童的平均dmfs为10.2。在波特兰队列中，3年乳牙龋齿平均增加量为1.5个牙面；在艾肯市白人队列中为3.3个牙面，在艾肯市黑人队列中为2.8个牙面。这些增加量在邻面和窝沟面之间平均分配。波特兰20%的儿童患了75%的龋齿；在艾肯市，20%的儿童患了60%的龋齿。这种分布表明存在一个高危群体，如果能够识别风险因素，就可以针对该群体采取积极的龋齿预防措施。
