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.
II型牙本质发育异常（DD-II）是一种罕见的遗传性疾病，会影响冠部牙本质，常导致牙髓石和复杂的牙髓治疗。本病例报告介绍了一名11岁女性患者DD-II的牙髓治疗情况。该患者因根管治疗前来就诊，表现出中度疼痛症状，被诊断为19号牙牙髓坏死；影像学检查发现多个牙髓石、根管钙化和根尖透射区。进行了牙髓治疗，包括用超声尖去除牙髓石、仔细清理和预备根管，并用牙胶和AH-26封闭剂进行充填。治疗后12个月，患者根尖病变完全愈合，无相关并发症。本病例强调了早期诊断和及时牙髓干预对DD-II患者获得良好预后的重要性。
