Abstract
An instrument for reaming a root canal, in particular, in the apical zone, includes proximal portions for receiving a handle which allows the instrument to be used by hand or on the head of a dentist's contra-angle handpiece, and distal portions having a blade with a pointed tip of a known type. The active, cutting part of the blade has, from the pointed tip and continuing along the blade, two conical sections. In addition to the pointed tip, each of the conical sections has a greater conicity than the least distal part adjacent to it. The instrument is useful for reaming root canals using a sequence of instruments which avoid root weakening and the flow of filling material from the end of the canal.
