Biologic Failure vs. Mechanical failure of endodontic treatment

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

Nickel-Titanium (NiTi) endodontic files have brought a big step toward “efficient” practice of endodontic procedure. The NiTi files help clinicians not only reduce their working time but also increase the clinical success rate with minimal procedural errors. Now various kinds of NiTi instruments are the “essential” equipment for the root canal preparation over stainless-steel instruments. 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 which may bring a different resulting root canal shape including potential aberrations. Clinicians also need to consider the basic biologic principle for root canal preparation and to give sufficient efforts for preservation of root dentin integrity. This lecture will give an insight based on research evidences for the usage of endodontic instruments with minimal risk of fracture as well as root dentin preservation.
