Dentinogenesis Imperfecta Type 2: a Case Report

Dentinogenesis imperfecta type 2, also referred to as Capdepont teeth and hereditary opalescent dentin, is a rare hereditary dysplasia affecting the dentin that occurs during the histodifferentiation stage of tooth development. The resulting brownish gray opalescent hue creates an unesthetic appearance. This form of dentin anomaly occurs in approximately 1 in 8000 individuals in the United States. Teeth affected by hereditary dentin dysplasia chip easily, even under normal masticatory forces; however, as a result of underlying sclerotic dentin formation and obliteration of pulp chambers in response to attrition, these teeth are not hypersensitive. This case report describes this rare anomaly in a 27-year-old woman, whose discolored teeth were restored with ceramic laminate veneers.
