Dentinogenesis Inperfecta. Report of three cases in an Indian family.

An Indian family with Type II Dentinogenesis Imperfecta is reported in which the pedigree was traced through four generations. Clinical and radiological examination was done in three individuals in the family studied, which showed variation in expression of colour and attrition. No clinical evidence of Osteogenesis Imperfecta was noted in any of the family members. Theoretical considerations regarding the development of this disorder and its clinical features are presented.
