Thirteen-year-old boy with dentinogenesis imperfecta - pedodontic and orthodontic treatment.

Dentinogenesis imperfecta is a hereditary condition characterized by disturbance in tooth formation. The colour of the teeth vary from opalescent greyish-blue to an amber-like colour on the teeth with splitting of the enamel. On the roentgenogram the marked obliteration of the pulp chambers is a characteristic feature. This case report describe a 13-year-old boy with dentinogenesis imperfecta. High caries activity resulted in extensive caries on the first permanent molars. The boy had to be treated orthodontically to create acceptable occlusion. The treatment was carried out with fixed appliance and started after extraction of the four first permanent molars. No observable injury was recorded during the treatment.
