There are many instruments and techniques for cleaning and shaping the root canal system, but none achieves the ideal preparation, especially in curved canals. This study compared the step-back technique, using Heliapical and Flexofiles, with the Canal Master technique, using Canal Master U instruments. The Bramante method evaluated and compared the results. Final analysis showed that root canals prepared with Canal Master U instruments and technique were significantly rounder, and had less transportation than those prepared by the Heliapical and Flexofiles using the step-back technique. |
