Abstract
It is important that baseline studies of dental caries prevalence are available prior to the introduction of community water fluoridation. This survey was carried out during the winter of 1975/76 in the low-fluoride Barnsley Area, England, United Kingdom, (F = 0.1 parts/106). Caries prevalence was in accord with that of other low-fluoride areas. The mean dmf [decayed, missing or filled] index was 4.5. For the group of children with rampant dental caries, the mean dmf value was much greater (11.3).
