Endodontic treatment of a geminated maxillary second molar using an endoscope as magnification device

Aim: To describe endodontic treatment for a rare case of gemination. Summary: 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. Key learning points: • 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.
