[Comparative studies on the incidence of caries in 10-year-old schoolchildren from Kiel and Landskrona (Sweden)].

Comparative clinical studies on the caries incidence of 10-year-old school children in Kiel and Landskrona (Sweden) showed after statistical evaluation that the Landskrona children had lesser DF surfaces than the Kiel children. A comparison of incidence broken up into separate D and F surfaces showed that the Kiel children had more D surfaces, while the children of Landskrona had more F surfaces. The connection between caries incidence and prophylactic measures is discussed.
