[Clinical-radiological studies on 3 siblings with double-formations of their milk front teeth]

Double anomalies of the lower lateral anterior deciduous teeth of three siblings were studied clinically and radiographically. In one case, the double anomalies were demonstrable in the permanent tooth germs. Various differentiation stages of schizodontia were observed. Apparently, the anomalies were genetically determined in the three cases. Effects on the change of teeth as well as anomalies in the shape and number of the permanent teeth were reported.
