ABSTRACT:
An endodontic operating instrument is disclosed for utilization in the preparation of root canals, either manually or in conjunction with ultrasonic or other instrumentation. The instrument per se includes an elongate shank of virtually any cross section desired and a handle or attachment means on one end so that the instrument may be operated manually by simply grasping the handle; operated by means of a conventional dental handpiece by simply attaching the attachment means thereto; or operated by means of an ultrasonic instrument. The instruments have a coating of abrasive material applied to at least a portion of their exterior surfaces to facilitate the preparation of the root canal by the action of the abrasive on the tooth.
