Endodontic Management of Dentin Dysplasia Type II in a Pediatric Patient: A Case Report

Dentin Dysplasia Type II (DD-II) is a rare genetic disorder that affects the coronal dentin, often leading to pulp stones and complicated endodontic treatment. This case report presents the endodontic management of DD-II in an 11-year-old female patient. The patient, referred for root canal treatment, exhibited symptoms of moderate pain and was diagnosed with pulp necrosis in tooth #19; radiographic findings revealed multiple pulp stones, pulp canal calcification, and apical radiolucency. Endodontic treatment was performed, involving the removal of pulp stones with ultrasonic tips, careful cleaning and shaping of the root canals, and obturation using gutta-percha and AH-26 sealer. Twelve months post-treatment, the patient showed complete healing of the apical lesion, with no related complications. This case underscores the importance of early diagnosis and timely endodontic intervention for favorable outcomes in patients with DD-II.
