Dental caries in schoolchildren in some Danish communities with and without school dental service.

The purpose of the investigation was to compare the caries prevalence (DMF-T) among 762 7th grade children, of whom one-half had never received school dental care. The children were grouped according to social status in order to see if there was any difference in the caries prevalence between the social groups. The caries prevalence in children both with and without school dental service was high, 9.5 DMF-T and 10.5 DMF-T. The prevalence of untreated caries and secondary caries was lowest in the group with school dental service.
