To describe endodontic treatment for a rare case of gemination.
A case of complex endodontic treatment in a geminated tooth is presented. With the assistance of microinstruments and magnification devices, a geminated maxillary second molar was successfully treated. In such a case, ultrasonic tips and the use of an endoscope were essential to detect the peculiar anatomy of the tooth involved.
Knowledge of anomalies concerning fused teeth is essential. Using an endoscope as a magnification device is useful during the inspection of pulp chambers. Ultrasonic tips are safe and useful to detect canal orifices.
描述一例分牙的根管治疗。
介绍一例分牙的复杂根管治疗病例。借助显微器械和放大设备，成功治疗了一例上颌第二磨牙分牙。在这种情况下，超声工作尖和使用内窥镜检查有助于发现受累牙的特殊解剖结构。
了解融合牙相关的异常情况非常重要。使用内窥镜作为放大设备有助于检查牙髓腔。超声工作尖安全且有助于探测根管口。
