Dentin dysplasia type I—report of a case treated with dental implants

Abstract

Dentin dysplasia (DD) type I is a hereditary disturbance in dentin formation. In this anomaly, the teeth generally appear clinically unremarkable with normal crowns; and radiographically it is characterized by normal appearing crowns, absence or severe restriction of root formation, obliterated pulp chambers, and periapical radiolucencies without an obvious cause. Clinically, the teeth can be poorly aligned, drifting and mobile, and can prematurely exfoliate due to abnormal root formation. This condition is rarely encountered in dental practice. Little is known about the specific treatment of this disorder and management of patients with DD has presented with problems. This report documents a case of DD type I in a 19-year-old male and the clinical, radiographic, and histopathologic findings of this condition and treatment are described.
