This report describes a permanent maxillary incisor tooth with two roots possibly caused by trauma to the predecessor primary tooth.
Diagnosis, aetiology, clinical implications and endodontic and aesthetic treatment of an incisor tooth with two roots are presented. Diagnosis, early intervention by a multidisciplinary team and clinical and radiographic examination of patients who suffer trauma to primary teeth are of importance to minimize or avoid damage to successor teeth.
• A possible sequelae of trauma to a primary tooth is root duplication in the permanent tooth. • Root duplication is a rare anomaly that has its diagnosis based on the radiographic examination. • Careful diagnosis and follow-up are necessary to prevent future complications related to the successor tooth.
本报告描述了一颗可能由于对前牙乳牙外伤导致具有两个根的上颌恒切牙。
本文介绍了一颗具有两个根的切牙的诊断、病因、临床意义以及牙髓病和美学治疗。对遭受乳牙外伤的患者进行多学科团队的早期干预以及临床和影像学检查，对于将对后继恒牙的损害减至最小或避免损害至关重要。
乳牙外伤的可能后果是恒牙的根分叉。
根分叉是一种罕见的异常，其诊断基于影像学检查。
仔细的诊断和随访对于预防与后继恒牙相关的未来并发症是必要的。
