Background: In routine endodontic practice most common clinicians encounter obstructions, such as hard impenetrable pastes, separated instruments, silver points or posts in their root canals. Cleaning and shaping of a tooth with intracanal separated instrument has a potential impact on the outcome of treatment. Broken instruments usually prevent access to the apex and the prognosis of teeth with broken instruments in the canals may be lower than for normal ones. Ultrasonicshave often been advocated for the removal of broken instruments because the ultrasonic tips or endosonic files may be used deep in the root canal system. Furthermore, the use of an ultrasonic endodontic device is not restricted by the position of the fragment in the root canal or the tooth involved. This case report elaborates on retrieval of broken instrument lodged at the coronal third of the canal of a permanent left maxillary first molar using ultrasonic technique.
Keywords: Separated instrument, ultrasonics.
