ABSTRACT

Endodontic file fracture is a common problem in root canal treatment. This may be due to overuse of instruments or incorrect technique in root canals with difficult anatomy. However, a broken endodontic file does not always mean that treatment has failed. Frequently the broken fragment can be removed, and the root canal treatment completed. Separation of a file usually occurs in molars, mainly in the mesiolingual canal due to major curvature, poor access or small diameter. Aim: This article reports the management of an intracanal separated NiTi instruments under operating microscope using ultrasonic technique. Observation: A patient in good general condition was referred by a colleague following an instrument fracture (SX file) in the left mandibular 2nd molar (37). Radiographic examination revealed the presence of a 4mm instrument blocking the middle third of the M°L root. To clean and disinfect the part of the canal beyond the instrument fracture, we decided to remove the instrument from the canal using an ultrasonic technique under an operating microscope. Discussion: Advances in technology have provided a number of tools for the extraction of files, including ultrasonic devices, with the aid of a microscope to facilitate visibility and minimise extraction of dentin from the root canal. Therefore, this report discusses the management of a broken file in a mandibular molar using an ultrasound device with the aid of a microscope. Conclusion: The ultrasonic technique is effective for the removal of broken instruments. Direct, visible access to the fragment under the dental microscope is essential for successful fragment recovery.
