Managing teeth with open apices can be a challenging scenario for clinicians. This case report describes the 24-year follow-up of a maxillary central incisor that failed to develop after a traumatic injury resulting in a wide-open apex. A 10-year-old girl presented complaining of discomfort in her upper teeth. Tooth #9 had received a traumatic blow several years before and was discoloured with a resin composite restoration on the mesio-incisal edge. The tooth was painful to percussion and palpation. An inadequate root canal filling and incomplete root formation were observed on the initial periapical radiograph. Root canal retreatment was initiated, and the canal filled entirely with mineral trioxide aggregate (MTA) because of the extremely wide canal and open apex. The patient was asymptomatic at the 24-year follow-up with the cone beam computed tomography and periapical radiographs demonstrating the stability of the MTA.
对于临床医生来说，处理根尖开放的牙齿可能是一个具有挑战性的情况。本病例报告描述了一颗上颌中切牙在创伤性损伤后未能发育，导致根尖完全开放，并进行了24年随访的情况。一名10岁女孩前来就诊，主诉上牙不适。9号牙几年前曾受过外伤撞击，牙齿变色，近中切缘有树脂复合树脂修复体。该牙叩诊和触诊时疼痛。初次根尖片显示根管充填不充分且牙根形成不完全。开始进行根管再治疗，由于根管极宽且根尖开放，根管完全用三氧化矿物凝聚体（MTA）充填。在24年随访时，患者无症状，锥形束计算机断层扫描和根尖片显示MTA稳定。
