Instruments and associated methods for performing endodontic treatment and that demand less time and fatigue onto the dentists and patients, while presenting the following accomplishments: debride the root canals in three dimensions and performing the optimal treatment； shape the root canals to facilitate the irrigation； these instruments are resistant to breakage and pressure while operating at high speed and torque； the instruments are capable of bypassing most obstacles, broken files, hypercalcification, curved roots canals, shoulders, and residual resistant pastes； and they present an alternative to arduous and expensive surgeries like endodontic or implant surgeries. As a result, they prevent fractures and procedural errors in making false canals or perforations of the root canals.
