Dentinogenesis imperfecta or capdepont’s teeth is an autosomal-dominant trait with variable expressivity. It affects dentin of both the primary and permanent dentitions. This condition is also called as hereditary opalescent dentin because of clinical discolouration of teeth. In this case report we are presenting a case of dentinogenesis imperfect type II with the disease affecting two generations of a family. The purpose of this report is to highlight the features of this disease and to differentiate it from its other variables. Early diagnosis and intervention with preventive strategies are recommended to prevent the deterioration as well as to improve the dental aesthetics and general health of the patient.
