ABSTRACT:
The present invention discloses a self-contained dental prophylaxis angle with an offset rotational axis and methods for its use in cleaning, polishing, bleaching, bonding, etching, abrading, desensitizing, or otherwise treating teeth. Therapeutic content, such as dentifrice, is contained within the inventive prophylaxis angle, and is dispensed subject to operator control during use of the prophylaxis angle. An offset drive system is provided to power rotation of the dental tip in a system that can be physically separated from the storage and dispensing system for therapeutic content. A self-contained dental prophylaxis angle with an offset rotational axis according to the present invention may be used with a variety of shaped dental tips of varying degrees of rigidity, according the needs of a given clinical application.
