Abstract

One of the most common mishaps that occur during routine endodontic treatment is the fracture of instrument inside the root canal. The separated instrument, particularly a broken file leads to metallic obstruction in the root canal and prevents thorough cleaning and shaping procedures. Continuous pain or discomfort occurs in the involved tooth if the broken instrument is not removed or bypassed. There are several methods and techniques available to retrieve the separated instruments from the root canal. This article describes the successful removal of a broken instrument from the root canal of a maxillary central incisor using Instrument Removal System (iRS) followed by healing of a large radiolucency applying non surgical approach in relation to maxillary central and lateral incisors.
