[Problems and characteristics of the orthodontic treatment of a patient with adrenogenital syndrome].

This article describes biochemical relationships accompanying pathological symptoms of C-21-hydroxylase deficiency (adrenogenital syndrome). Disturbances of bone growth and development have been observed, even during medical treatment. A discrepancy of 2 1/2 years was noted between the patients chronological age and his bone development. The patient reaches a maximum height of 155 to 160 cm. Supernumeraries and delayed mineralisation are to be expected. Surgical procedures require an increase in cortisone dosage. When considering orthodontic treatment, one must determine the most appropriate time to start, take into account the long retention period and pay particular attention to oral hygiene.
