Retrieval of Separated Instrument: A Case Report

Abstract

Instrument fracture is one of the most common endodontic mishap during root canal therapy. Separated instrument results in inadequate cleaning and shaping of root canals. Inadequate biomechanical preparation affects the outcome and prognosis of root canal treatment. Hence retrieval of the separated instrument should be considered as an option. Various instrument retrieval kits and techniques are available for this purpose. In the present case report a separated rotary instrument was successfully retrieved from the distal canal of mandibular second molar using Masserann kit and file braiding technique.
