Advanced Instrumentation for the General Practice Dental Hygienist
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.
