Abstract: Intracanal separation of instruments usually prevents access to the apex and impedes thorough cleaning and shaping of the root canal, and thus may compromise the outcome of endodontic treatment and reduce the chances of successful retreatment. Hence every attempt should be made to bypass or retrieve the separated instrument. The main purpose of this article is to create awareness among the practicing dentist regarding the retrieval of broken instrument that may occur as a procedural problem while performing an endodontic treatment. Case report described here is about the successful retrieval of a separated H-file that may be tightly wedged in the root canal dentin of maxillary molar of the left side. The separation of instruments while performing root canal procedure is a troublesome event that may block access to the apical terminus. Retrieval of separated instruments by the use of simply k file to different retrieval kits along with dental magnification like dental loupes or dental operating microscopes makes the procedure of retrieval a more effective. However, prevention of the instrument separation is the best strategy to avoid any stress and anxiety associated with it. Prevention of file separation is always more desirable than attempted removal.
