[Preventive measurement in Gottingen kindergartens from 1975-1990].

Abstract

379 children, age 3 to 6, were examined for caries prevalence in kindergartens in Göttingen. 64% of subjects had healthy natural dentitions, the df-s value was 2.3. In 1990 the mean df-s value for 4-5 year old children was 10% lower than 1985 and 45% lower than 1983. Oral health had improved differently in the various institutions. The mean df-s was between 0.6 and 4.7.
