Rotary files are typically powered by a handpiece that is connected to a dental drill. The dentist will use the handpiece to control the speed and torque of the file. The file is then inserted into the root canal and rotated to remove infected tissue and debris. Rotary files are safe and effective when used properly, and they have helped improve root canal treatment's success rate. Features: - Heat-treated NiTi files. - More cutting. - Better flexibility.
