Caries prevalence, treatment level, and sealant use related to school lunch program participation

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.
