Dentinogenesis imperfecta (DI) is a developmental hereditary condition (autosomal dominant) that affects the developing dentin. The dentin appears opalescent affecting both primary and permanent dentitions. DI can be classified into three main types: type I: DI associated with osteogenesis imperfecta; type II: DI similar to type I but not associated with osteogenesis imperfecta; and type III: initially reported in Brandywine population of Maryland and characterized by opalescent shell teeth (due to dentin hypotrophy) having marked attrition and large pulp chambers. As dentin forms the bulk of the tooth tissue, the teeth affected by DI are weak and prone to breakage and wear.
