ABSTRACT:
Improved methods and apparatus for the removal of plaque from interproximal areas of the dental anatomy and from periodontal pockets. An reciprocal or orbital vibratory motion about the longitudinal axis of the bristles is utilized to impart frictional forces from a multitude of bristles positioned within the interproximal area of two adjacent teeth and in the periodontal pockets of the gum. An advanced embodiment utilizes ultrasonically enhanced bristle tufts to transmit ultrasonic vibrations into the gingival fluids in the periodontal pockets, producing standing ultrasonic waves within the gingival fluids which augments and enhances the plaque removal capability of the reciprocally or orbitally vibrating nylon bristles.
