A RARE CAS E OF DENTIN DYSPLAS IA TYPE I

Dentin Dysplasia (DD) is a rare hereditary dentin disorder with autosomal do minant pattern of inheritance characterized by abnormal dentin structure affecting both the primar y and permanent dentitions. It is generally divided into 2 main classes based on the clin ical and radiographic appearance of the affected dental tissues: type I, wh ich affects the root portion and type II, wh ich affects the coronal portion of the tooth. The present case exh ibits defined features of DD type I, including clinically normal crowns, increased tooth mobility, rad iographic obliteration of pulp chambers and root canals, short blunted roots and periapical radiolucencies in non-carious teeth in a 24 year old-male patient. Early diagnosis of the condition and initiation of effect ive regular dental trea tm ents may help to prevent or delay loss of dentition in these patients.
