Root canal shaping is a critical phase of endodontic treatment, as it creates the conditions required for effective disinfection and three-dimensional obturation. In recent years, advances in nickel–titanium alloys, instrument design, and kinematics have led to safer, more efficient, and less complex preparation protocols. Among these developments, single-file systems aim to simplify the clinical workflow while maintaining control and respecting the original root canal anatomy.
However, simplicity should never come at the expense of safety or predictability. Can a single instrument adequately manage the wide anatomical variability encountered in daily practice? How should glide path management, working length determination, shaping, and irrigation be integrated into a coherent clinical protocol? And in which cases might the preparation strategy need to be adapted?
This webinar will provide an up-to-date and clinically oriented overview of modern root canal shaping using the Zen ONE single-file system. Particular attention will be given to case selection, safe instrumentation, preservation of tooth structure, irrigation, and the achievement of predictable clinical outcomes.
