AbstractCleaning and shaping of the root canal space is the primary objective of endodontic therapy. Its purpose is to prepare the canal space in order to improve disinfection with the use of irrigants as part of chemo mechanical preparation. Infiltration and subsequent infection of the root canal system by microorganisms and their byproducts is the primary etiology of endodontic pathosis. Chemo-mechanical preparation aims to remove microorganisms, remaining pulp tissue and dentin debris from the root canal system.
The main objective of shaping is to maintain or develop a continuously tapering funnel from the canal orifice to the apex; however the complex canal anatomy causes instrumentation challenges, which may prevent adequate disinfection of the root canal system, or cause procedural errors such as instrument separation, transportation, ledges or perforations. The present study was set out to determine canal centering ability, transportation and curvature using 5th generation NiTi rotary systems as mentioned above.
