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.
