Dentinogenesis imperfecta: endodontic implications. Case report.

Dentinogenesis imperfecta is a hereditary disorder resulting in defective dentin in both the primary and secondary dentitions. The complications of dentinogenesis imperfecta are difficult to manage and provide a challenge to the dentist. This case report concerns treating an African American patient with dentinogenesis imperfecta who appeared for treatment with endodontic pathosis. It illustrates the need for appropriate and timely restorative treatment to prevent pulpal pathosis. Also demonstrated is the difficulty of endodontically treating dentinogenesis imperfecta teeth because of pulpal obliteration and abnormal dentin mineralization. Early and correct diagnosis of dentinogenesis imperfecta is imperative to enable appropriate preventive interventions and optimal dental treatment. Although pulpal pathosis is rarely reported with dentinogenesis imperfecta, endodontic treatment is occasionally necessary and has a guarded prognosis if initiated after pulp canal obliteration has occurred.
