Abstract
A method of fabricating an endodontic instrument having depth indicating calibrations formed between the handle and the fluted tapered end portion, and wherein the calibrations are formed by a cold rolling operation. The rolled calibrations do not form fracture points, they may be rapidly and inexpensively formed, and they have a smooth surface finish. Further, the rolled calibrations provide a sufficient physical indentation to be readily visible on x-ray photographs.
