These files, used in conjunction with the Elements Motor featuring Adaptive Motion, can safely and accurately clean and shape root canals. The Adaptive Motion relies on a patented algorithm that changes the motion of the file based on the applied load. This results in better file control for the clinician with less chance of file breakage. TF™ Adaptive Files feature a unique color code that uses the universally understood “stop light” as the guide: green means go, yellow means stop or keep going, and red means stop. The single color band is for small files, and the double color band is for medium/large files.
