ABSTRACT:
A system for establishing a cumulative history of stress factors encountered during use of an endodontic file and keeping track of such for a plurality of files so that the files can be re-used with confidence that a given file is as safe to use as a new file. Cost of file maintenance is significantly reduced and the likelihood of file breakage in use is minimized.
