ABSTRACT:
Endodontic files which provide constant dentin volume removal from file to file based on the actual volume of dentin removed from file to file. Each file removes exactly the same increase in volume as its predecessor. In this manner, a clinician may use each file in a sequential manner from smallest to largest without the need to alternate sizes or rely on subjective factors. Correspondingly, the time required to prepare a patient's root canal drops as a function of the reduced need to interchange sizes along the way and provide a clinical method of preparing root canals that relies on objective clinical techniques.
