Abstract

Ultrasonic retrieval of endodontic separated instruments, although proven to be highly successful, is a technique-sensitive process that might be accompanied by various complications including root lateral perforations, instrument secondary fractures, and unnecessary removal of radicular dentin, which in turn increases the odds of dentinal microcracks development and root fractures. Such complications increase the case difficulty and might lead the operator to modify the original treatment plan. The current case report describes the management of a separated Endo-Z bur, in a maxillary canine, that underwent a secondary fracture during ultrasonic retrieval. Ultrasonic application retrieved the coronal segment of the instrument, leaving behind a more apically located secondary fractured segment that would have sacrificed much more radicular dentin if removed ultrasonically. Therefore, the remaining fragment was bypassed using stainless steel hand files, and the braiding technique was alternatively used and successfully removed the apically located instrument conservatively.
