Abstract
Methods for modifying a physical characteristic of finished endodontic instruments made from one or more superelastic alloys is described which include heat treating one or more finished endodontic instruments in a salt bath for a specific time (e.g., from about four hours to about six hours), at a specified temperature (e.g., from about 475° C. to about 550° C.), and preferably at a specified pH range.
