Periodontal Files

Periodontal files are used for debridement in deep pockets. They are excellent for breaking up tenacious or large calculus deposits. The design has a series of parallel blades on a flat head that can crush the deposits (Figures 47a‑b). There must be good access to the area in order to use this instrument effectively. Files are typically utilized with a pull stroke.
