Abstract

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.

使用 MTA 填充整个牙道，成功再治疗了一颗牙尖宽大的上颌中切牙：24 年随访。

对于临床医生来说，处理牙尖开放的牙齿是一种具有挑战性的情况。本病例报告描述了对一颗上颌中切牙 24 年的随访情况，这颗上颌中切牙在一次外伤后未能发育，导致牙尖开放过大。一名 10 岁女孩主诉上牙不适。她的 9 号牙齿在几年前受到过一次外伤，中切缘的树脂复合修复体已经变色。叩诊和触诊时牙齿疼痛。在最初的根尖周炎 X 光片上可以看到根管充填不充分，牙根形成不完整。由于根管极宽且根尖开放，因此开始了根管再治疗，并用三氧化物矿物质骨料（MTA）完全填充了根管。在 24 年的随访中，患者没有任何症状，锥形束计算机断层扫描和根尖周X光片显示 MTA 很稳定。

期刊介绍： The Australian Endodontic Journal provides a forum for communication in the different fields that encompass endodontics for all specialists and dentists with an interest in the morphology, physiology, and pathology of the human tooth, in particular the dental pulp, root and peri-radicular tissues. The Journal features regular clinical updates, research reports and case reports from authors worldwide, and also publishes meeting abstracts, society news and historical endodontic glimpses. The Australian Endodontic Journal is a publication for dentists in general and specialist practice devoted solely to endodontics. It aims to promote communication in the different fields that encompass endodontics for those dentists who have a special interest in endodontics.
