Abstract
An endodontic file is provided for use in root canal procedures. The file has an elongated blade with cutting edges formed on the lower portion thereof and having a shank at its upper portion. A file head is provided having a passageway formed therein which receives the shank of the blade. The end of the shank is flared to prevent the shank from being drawn through the passageway in one direction. By anchoring the file blade in this manner, the use of a low profile handpiece is facilitated for ease of use in a patient's mouth.
