This paper makes a practical analysis about the paradigm on the instrumentation of curved root canals. In Endodontics, a paradigm has been created. Theories and techniques for instrumentation of curved root canals state that the use of a #25 file in the apical portion fulfills all the requirements for cleaning and shaping of the root canal system. Every scientific theory or paradigm should be continuously opened to modifications or refutation. The existence of extremely flexible instruments fabricated from metal alloys, methods for accurate determination of the real anatomic diameter and achievement of optimal shaping and cleaning of the apical portion created new theories and a new paradigm on the instrumentation of curved root canals. Therefore, this new insight will gradually modify the mentality of researchers and clinicians, but will still be open to further investigations and theories.

Keywords : paradigm; root canal instrumentation; curved root canals.
