Abstract
A non-landed endodontic instrument has flutes formed along a working length of the instrument shaft. The flutes define cutting edges for shaping a root canal of a tooth. The cutting edges lie at a major diameter of the shaft and peripheral flute surfaces behind the cutting edges extend along decreasing radial distances from the center of the shaft, in a direction opposite the cutting direction of the instrument.
