Radiological features of hereditary opalescent dentin.

A case of hereditary opalescent dentin is described, which showed the same clinical and radiological features as those reported previously. However, there was no evidence of osteogenesis imperfecta. While a diagnosis of type II dentinogenesis imperfecta was therefore made, this case also had features characteristic of type III dentinogenesis imperfecta. Treatment by means of an overdenture is described.
