Abstract
Instrument breakage is a common mishap where management options are reduced especially in a curved canal with restricted visual access. Bypassing the fractured instrument represents the most conservative way to deal with this obstacle without compromising the disinfection of the root canal. The aim of this article was to report a case of management of an acute curvature with two broken files with one of them partially extruded beyond the apex. bypassing of the broken files and negotiating the severe curvature was done after a meticulous study of the pre-operative radiography that assessed the case difficulties and helped us strategize the use of adequate instruments and techniques. Afterwards we will describe the instrumental management protocol to bypass the two broken files prior to the filling of root canals.
