A total of 2,753 schoolchildren (8-11 years old) from two school districts received visual-tactile examinations for caries. The school districts were approximately 15 miles apart and located in fluoride-deficient (F less than 0.3 ppm) Long Island, New York. The higher socioeconomic community (HSES) had 9.2 percent of its students enrolled in the free or reduced-payment school lunch program; the lower socioeconomic community (LSES) had 50.3 percent enrolled. The LSES community had a higher caries prevalence, more untreated lesions, fewer caries-free children, and fewer children treated with sealants. School lunch programs provide an index to identify communities for dental programs.
来自两个学区的总共2753名8至11岁的学童接受了龋齿的视触觉检查。这两个学区相距约15英里，位于纽约州氟缺乏（氟含量低于0.3 ppm）的长岛。社会经济水平较高的社区（HSES）有9.2%的学生参加免费或减价学校午餐计划；社会经济水平较低的社区（LSES）有50.3%的学生参加。LSES社区的龋齿患病率更高，未治疗的病变更多，无龋儿童更少，接受窝沟封闭治疗的儿童也更少。学校午餐计划为确定牙科项目的社区提供了一个指标。
