This case report describes the treatment of two immature maxillary central incisors in a 7-year-old female patient. She suffered complicated crown fracture because of trauma, and the root formation was incomplete. White mineral trioxide aggregate (MTA) was selected as the pulp-capping material after cervical pulpotomy to preserve the pulp tissue vitality and achieve maturogenesis. Follow-up evaluations showed successful treatment in terms of preservation of pulp vitality and demonstrated marked continuous physiological root development. During 10 years of follow-up, both teeth were clinically asymptomatic, and radiographic evaluations showed apparent root regeneration with apical root-end closure without pulp or periapical pathosis.
本病例报告描述了一名7岁女性患者两颗未成熟上颌中切牙的治疗情况。她因外伤导致复杂的冠折,牙根形成不完全。在进行颈部牙髓切断术后,选择白色矿物三氧化物凝聚体(MTA)作为盖髓材料,以保存牙髓组织活力并实现牙根继续发育成熟。随访评估显示,在保存牙髓活力方面治疗成功,并显示出明显的牙根持续生理性发育。在10年的随访期间,两颗牙齿临床均无症状,影像学评估显示牙根明显再生,根尖孔闭合,无牙髓或根尖周病变。
