[Karyotype studies in cases of hereditary hypodontia].

The Authors examined 22 families (including 67 individuals) in whose components one or more teeth were found to be congenitally missing. The morphological characteristics of the chromosomes were analyzed with the technique of Moorhead to observe any aberration in shape, size and pattern. With such method, no alteration of the karyotype was shown in case of oligodontia.
