[Annual mass examinations to epidemiology of dysgnathisms of city children attending créches]. / Jährliche Reihenuntersuchungen zur Epidemiologie von Dysgnathien bei Grossstadtkindern im Krippenalter.

In a period of twelve years (1975-1986) the children of the group 2(6)/12-3 years old were investigated in the créches of Berlin-Mitte district. The frequency of dysgnathisms is constant nearly 50%. In contrary to this the frequency of caries has decreased continuously. It is necessary to treat habits as soon as possible. Unfavourable cases of habits strengthen the tendency to dysgnathisms. In cases the tendency can not removed by preventive management, the treatment of temporary teeth by functional orthodontic management should be required.

[The extraction of the 6-year molars in orthodontic practice]. / Zur Extraktion der Sechsjahrmolaren in der kieferorthopädischen Praxis.

Nevertheless, one-third of all permanent teeth extracted by us in orthodontic cases terminated within one year were first molars. The indication for the extraction of these permanent first molars was based exclusively on caries incidence. The resultant disadvantages to the course of treatment are discussed from medical and economic aspects.
