Dentinal dysplasia (DD) Type I, is a hereditary disturbance in dentine formation. In this anomaly, teeth in both primary and secondary dentitions are affected, and radiographically show short and blunted roots with obliterated root canals and periapical pathosis. Management of patients with DD has presented dentists with problems. Extraction has been suggested as a treatment alternative for teeth with pulp necrosis and periapical abscess. Follow-up and routine conservative treatment is another choice of treatment plan in DD. Another approach for the treatment of teeth with DD has included periapical surgery and retrograde filling, which is recommended in the teeth with long roots. The purpose of this report is to present an unusual case of dentinal dysplasia Type I in a 22-year-old woman showing upper and lower teeth with obliterated root canals and periapical radiolucencies. In this case, conventional endodontic treatment was performed. Postoperative radiographs and clinical evaluation demonstrated periapical healing and successful results. Based on the results of this case report, conventional endodontic treatment for cases with pulp necrosis and periapical radiolucencies in dentinal dysplasia is highly recommended.
I型牙本质发育异常（DD）是一种牙本质形成的遗传性紊乱。在这种异常情况下，乳牙列和恒牙列中的牙齿都会受到影响，X线片显示牙根短而钝，根管闭塞且根尖周病变。DD患者的治疗给牙医带来了难题。对于牙髓坏死和根尖周脓肿的牙齿，拔牙被建议作为一种治疗选择。随访和常规保守治疗是DD治疗方案的另一种选择。治疗DD牙齿的另一种方法包括根尖手术和倒充填，这在牙根较长的牙齿中推荐使用。本报告的目的是呈现一例22岁女性的I型牙本质发育异常的罕见病例，其上下牙齿根管闭塞且根尖周有透射区。在该病例中，进行了常规牙髓治疗。术后X线片和临床评估显示根尖周愈合且结果成功。基于本病例报告的结果，强烈推荐对牙本质发育异常中伴有牙髓坏死和根尖周透射区的病例进行常规牙髓治疗。
