Abstract :
Managing curved root canals in endodontics poses considerable challenges due to their complex anatomy and increased risk of complications during treatment. Successful outcomes depend on accurate diagnosis, detailed planning, and the use of advanced instruments and techniques. Pre-operative imaging, including periapical radiographs and cone-beam computed tomography, plays a vital role in identifying the degree and direction of canal curvature, allowing for appropriate treatment planning. The introduction of heat-treated nickel-titanium instruments with enhanced flexibility and shape memory has greatly improved the ability to shape curved canals while minimizing procedural errors. Effective irrigation using advanced techniques such as ultrasonic or sonic agitation ensures better cleaning of areas that instruments cannot reach. Obturation in curved canals is often difficult, but the use of flowable and biocompatible sealers, such as resin-based or bioceramic types, enhances sealing ability and long-term success. A thorough understanding of root canal morphology, along with the use of modern tools and techniques, is key to achieving predictable and successful outcomes in curved canal cases.
