Non-surgical Retrieval of Separated Endodontic Files Using Ultrasonics and Braiding Technique: A Case Series.

Managing endodontically treated teeth with canal obstructions, such as separated instruments, posts, metallic points, etc., presents a significant clinical challenge. Instrument separation during root canal therapy can compromise effective cleaning and shaping, potentially affecting the overall treatment outcome. The presence of a fractured instrument often limits access to the apical root canal region, impeding its adequate cleaning and thereby compromising the prognosis of the case. Therefore, retrieval of the separated fragment is essential to optimize clinical success. Among the various techniques available, ultrasonics has proven to be highly effective for removing fractured instruments by enabling precise navigation within complex canal anatomies. This case series details an efficient approach for the successful retrieval of separated instruments from the root canals using a combination of ultrasonic instruments, such as forceps and H-file.
