Radiolucent or hypodense lesions in the crown of unerupted teeth may be due to pre-eruptive intracoronal resorption. Clinicians must be aware of this risk so that they can diagnose and appropriately treat this condition. The purpose of this study is to present a well-documented clinical case of pre-eruptive intracoronal resorption in an impacted third upper left molar of a 63 year old female patient. This was an unexpected finding, which occurred after cone-beam computed tomography was used to investigate the first upper left molar, which had an acute periradicular abscess. A multidisciplinary team followed up the case to describe clinical, radiographic and histological findings. The available treatment options were discussed, and the tooth extraction was the option chosen. Previous case studies describing such resorption in third upper molars have not been reported. This case shows that all permanent teeth in a pre-eruptive stage must be analysed radiographically to detect early pre-eruptive intracoronal resorption.
未萌出牙冠内的射线可透性或低密度病变可能是由于萌出前冠内吸收所致。临床医生必须意识到这种风险，以便能够诊断并妥善治疗这种情况。本研究的目的是呈现一例记录详实的临床病例，该病例为一名63岁女性患者左上第三磨牙萌出前冠内吸收。这是一个意外发现，发生在使用锥形束计算机断层扫描对左上第一磨牙进行检查时，该牙患有急性根尖周脓肿。一个多学科团队对该病例进行了随访，以描述临床、影像学和组织学检查结果。讨论了可用的治疗方案，最终选择了拔牙。此前尚未有描述上颌第三磨牙此类吸收的病例研究报道。该病例表明，必须对所有处于萌出前期的恒牙进行影像学分析，以检测早期萌出前冠内吸收。
