[Bite anomalies in familial Friedreich's ataxia].

Besides well-known deformations of the spine and foot in Friedreich's disease, special attention is drawn to the deformation of the maxillodental system, the state of which was not specially studied before. The authors detected pathology of occlusion in 16 of 24 patients with familial Friedreich's ataxia. As a rule this form of anomaly is combined with other bone deformations. In 2 families, where several patients were studied, there was the same occlusional pathology. On the basis of a study of 24 patients and control consisting of 151 individuals, the conclusion is made, that in Friedreich's disease, almost as frequent as deformations of the spine and foot there are also pathological occlusions.
