PDF: Procedural errors during root canal preparation using rotary NiTi instruments detected by periapical radiography and cone beam computed tomography

Endodontic teaching requires scientific knowledge and appropriate methodological strategies to optimize the use of materials and techniques.

Endodontics


Several challenges are present during undergraduate teaching, in particular, the recent conceptual changes in terms of the shaping of curved root canals.

It seems opportune to emphasize that shaping root canals is an essential phase on root canal treatment.

An important innovation that has a major impact on this procedure has been the introduction of rotary NiTi instruments. 


Rotary nickel-titanium (NiTi) instruments have been found to maintain working length (WL), allow root canal preparation to be more centered and better tapered, create fewer procedural errors when compared to stainless steel instruments, in addition to being faster.

A number of new rotary NiTi instruments with particular characteristics have been introduced over the last years. 

The promising potential of NiTi instruments in shaping curved root canals are thus available to undergraduate dental students during their training at the dental schools.
