Root canal perforations are defined as the communication between the pulp cavity, the periodontal tissue and alveolar bone. The occurrence of perforations during endodontic treatment is reported to range from 2.3%~12%, which is not a complication rarely happens. Perforations have iatrogenic or pathological etiologies that involve caries or resorption. It leads to inflammation and the destruction of periodontal fibers and alveolar bone, followed by periodontal defects. Mineral trioxide aggregate (MTA) is currently the most indicated material for repair of root perforation, because of its favorable biocompatibility and sealing ability. Using magnification with dental operating microscope enhance the accessibility and visibility to manage the root perforation. It is important to diagnose and repair perforations immediately if possible.
