[A familial strain of amelogenesis imperfecta hypoplastic type with dominant x-linked heredity]

Hypoplastic amelogenesis imperfecta in members of four generations of a Campanian family is described. The females were affected to a lesser degree. A dominant X-linked mutation was apparently involved. The different forms of amelogenesis imperfecta are described in the light of their anatomical, clinical and radiological pictures and their transmission modalities. Suitable corrective treatment is required to offset the damage to masticatory function, and associated psychological and emotional consequences, especially in female subjects.
