Dentinogenesis imperfecta: a review and case report of a family over four generations.

Dentinogenesis imperfecta (DGI) is one of the most common hereditary disorders of dentin formation. It follows an autosomal dominant pattern of transmission, affecting both the formation and mineralization of dentin. Either or both primary and permanent dentition is affected by it. This paper briefly reviews the manifestations of DGI Type II (DGI1) and presents a case report of a family affected with DGI1 over four generations.
