[Hereditary enamel dysplasia. Therapeutic approach apropos of 2 cases].

Two cases of hereditary dysplasia in the same generation of a family are presented. The genetic line is suggestive of a dominant transmission. The therapeutic attitude in each case: --Orthodontic, endodontic and prosthetic rehabilitation in the 1st case. At the patient's strong urging, a total fixed denture was made, which made it possible to correct moderate protrusion of the incisors and to obtain the aesthetic result desired by the patient. This work was carried out in the Stomatological Clinic of Lyon, by students working for their specialty certificate in stomatology. --In the case of the younger sister, the presence of a markde skeletal open-bite and the refusal of any surgical solution led to the total extractions requested by the patient. A mobile denture was made by her own dentist. Thus complete assessment and knowledge of the patient's precise wishes make it possible to adopt the most desirable therapeutic approach in each case.
