Abstract
Cleaning and shaping a root canal are two inseparable concepts of endodontics. Shaping facilitates the penetration of disinfecting solutions into the deepest regions of the root canal system, including those that cannot be reached by instruments. The Hero Shaper® is a leading system in the European market, and the concept of the ‘adapted Pitch’ is of particular interest. Modifying the pitch of this instrument has made it possible to limit the screwing effect of the file in the canal considerably and to improve flexibility. In this paper, the guidelines for use of these instruments are described. Manufacturer's recommendations are presented and modified by the use of Hero Apical® to achieve the fundamental principles of endodontics published by Herbert Schilder more than 30 years ago.
