Amelogenesis imperfecta and nephrocalcinosis: a new case of this rare syndrome.

This article describes a new case of a rare syndrome including enamel agenesis of the primary and permanent dentition, delayed or absent eruption of the permanent dentition, coronal intra-alveolar resorption and gingival enlargement. Renal symptoms include medullary nephrocalcinosis without any apparent cause, and evolution to a renal failure. The early diagnosis provided by the oral symptoms leads to a better renal prognosis. As a consequence, pediatric dentists should be aware of this pathology.
