Abstract
The invention is an improved endodontic apparatus attachment for holding instruments, particularly endodontic drill files that are energized and vibrated by ultrasonic means. The invention also provides for the flow-through of solutions during debriding and irrigating of root canals. The invention consists of a hollow tube-like means for conducting solution and directing it in the axial direction of the endodontic drill file. The hollow tube-like means incorporates a special holding means therein for mounting the drill file in such a position so that ultrasonic waves can be transmitted to the drill file to cause it to vibrate in a manner that improves debriding of the root canal.
