Techniques and Innovations
Advanced techniques for managing curved root canals have transformed the
approach to treatment by improving our understanding of anatomy and
minimizing risks during procedures. Heat-treated NiTi instruments have
enhanced flexibility and resistance to cyclic fatigue, thus reducing
canal transportation and preserving natural anatomy (16). Finite Element
Analysis (FEA) application has improved instrument design and
development through the assessment of biomechanical stress associated
with the use of an instrument, hence making more durable rotary files
possible (26). Ultrasonic irrigation activation systems are effective in
cleaning and disinfecting the apical third of curved canals, which is
impossible with traditional methods (27). Thermoplasticized obturation
techniques improve sealing in irregular canals by adapting to their
natural morphology (16). Further, navigation systems assisted by
artificial intelligence have also proven to be a game-changer in precise
canal mapping and reducing operator errors (16). These collectively
enhance the success and predictability of treating curved canals. In
these cases, we used NiTi rotary files to instrument teeth followed by
NaOCl, saline, and EDTA with ultrasonic activation irrigation while the
warm obturation technique was used with AH Plus sealer.
