[Will fluoridation of the drinking water influence the extent of treatment in orthodontic extraction therapy?]. / Beeinflusst die Trinkwasserfluoridierung den Behandlungsumfang bei der kieferorthopädischen Extraktionstherapie?

Whether fluoridation of drinking water would have an influence on orthodontic extraction therapy and especially on selection of extraction objects was inquired. Treatment results of 256 patients of a town with fluoridation of drinking water (Chemnitz) who had extraction of teeth under their orthodontic treatment, were interpreted and compared with these of a district without fluoridation of drinking water (Berlin). Evident differences concerning extraction frequency of the various species of teeth were noticed.

[Indication and realization of orthodontic extraction therapy]. / Indikation und Durchführung der kieferorthopädischen Extraktionstherapie.

In establishing the indication for extraction therapy, careful consideration should be given to the unharmonious relationship of the jaw and teeth, the apical bone, the anlage of the wisdom teeth and hypodontia. Beginning with the narrow, contracted dental arch, where extractions are indicated most frequently, the different groups of anomalies are discussed. The most important rules and the optimal time are dealt with at the end of the present review article.
