[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.

[The Pierre Marie-Sainton syndrome].

Pierre Marie and Sainton syndrome, or cleido-cranial dysostosis is characterised by a triad: clavicular aplasia, delayed ossification of the fontanelles and sutures of the vault of the skull and hereditary transmission. To these may be added multiple dental inclusions - hence its interest in stomatology. The authors described a familial hereditary case affecting mother and son, the former with an incomplete syndrome and the latter with the complete picture of major dysostosis.
