Abstract
An endodontic instrument adapted for use in performing root canal therapy. The instrument includes a holder with a grip sized to be gripped by a hand of a user. An arm extends from the grip and has a length sufficient to permit a free end portion to reach into a patient's mouth while the grip remains outside the mouth. An elongate rod with a working portion having cutting portions thereon extends along the length of the arm of the holder such that a proximal end of the rod is adjacent the grip of the holder and the distal end of the rod with the working portion thereon extends from the free end portion of the arm, such that the working portion may be used to treat a root canal in a patient's mouth by a dentist manipulating the holder outside the mouth of the patient.
