[Christ-Siemens-Touraine syndrome. Therapeutic case review]

The Christ-Siemens-Touraine syndrome, or anhidrotic ectodermal dysplasia, presents three principal signs: anhidrosis or hypohidrosis, hypotrichosis and anodontia or hypodontia. This syndrome is of particular interest to stomatologists and orthodontists because of the particular therapeutic problems raised by the anodontia and associated skeletal anomalies. A case is reported in which the principal clinical sign was anodontia, and the various therapeutic options currently available are discussed.
