This paper describes a case report in which a separated file has been removed from the root canal of a maxillary central incisor using alternative H files and K files along with continuous irrigation
Summary
A clinician may come across a variety of problems and procedural errors during the routine course of endodontic treatment, which has a direct outcome on the success of the treatment. The separated fragment impedes access to thoroughly clean and shape the root canal apical to the level of separation or irritates the periapex when it juts out of the root apex All this in turn affects the final outcome of the treatment and prognosis of the tooth. Cyclic fatigue is more commonly caused by continuous stress applied to an instrument that has bee n weakened by metal fatigue and when point of maximum flexure is reached, breakage occurs This is commonly seen where the stress is greatest, most often in curved canals. Once the radiograph confirmed the bypass of the file uptill the apex, working length was measured (Fig. 2). Root canal treatment was completed with 11 and patient was advised to place crowns on both the anterior teeth (11and 21) (Fig. 4). When a no 40 K file was used the instrument loosened from the apex and was flushed
