Abstract

The use of Nickel Titanium mechanical endodontic instruments has changed forever the way canals are prepared and their advantages are many when compared to the well-documented disadvantages and inadequacies of hand instrumentation. However, many colleagues are reluctant to embrace the technology on the basis that techniques are too complicated, too many instruments are required to achieve the desired outcome and the fear of breakage continues.

Reciprocating file systems and their movement, advanced metallurgy, optimised tip diameters, tapers and an altered cross-section have improved safety, efficiency, and flexibility when shaping canals. In over 80% of cases, only ONE single reciprocating instrument is needed to shape the canal confidently, thus reducing the number of instruments in any given sequence to an absolute minimum.

During the present COVID-19 pandemic many dental offices are inundated with endodontic emergencies. Clinicians will need an efficient, rapid and very safe shaping technique so that adequate three-dimensional cleaning and obturation of the root canal system can be optimised for continued endodontic success. 

Shaping with a reciprocating single file system takes confidence and simplicity to another spectacular level.
