Instruments and Mechanical Implication on Clinical Efficiency


Endodontic treatment is mainly purposed to reduce/remove microorganisms and infected tissue from the root canal system. To reach this goal, clinicians need to follow the principles from the diagnostic procedures to post-endodontic restoration based on the rationale of endodontics. It is important to have knowledge about modern endodontic concepts and methods including contemporary materials, through which we can maintain a high success rate of treatments.  

Among the contemporary endodontic materials, nickel-titanium (NiTi) endodontic files have brought a big step toward “efficient” practice of root canal preparation procedure. The NiTi files help clinicians not only reduce their working time but also increase the clinical success rate with minimal procedural errors. Especially, recently introduced instruments made of heat-treated alloy in various designs made it possible to shape the root canals with minimal number of instruments and to preserve the root dentin integrity. 

Clinicians need to understand the characteristics of each instrument system and its mechanical properties as well as the basic principle of root canal shaping. This lecture will give an insight based on research evidence for the selection of endodontic instruments with minimal risk of fracture as well as root dentin preservation.
