title: Prevalence of gingivitis among children with and without school dental service.
abstract: In order to evaluate the effect of school dental care on the prevalence of gingivitis in children, two groups of children in the 7th grade (approx. age 13-14 years) were compared, only one of the groups having had school dental service. A  total of 758 children from eight different provincial towns in Denmark were studied. Gingivitis was recorded by the method of Löe & Silness. The results are given as the average sum of sound, inflamed, and severely inflamed gingival zones and in frequency tables. There were only small differences between those children who had had school dental service and those who had never received it.
