ABSTRACT:
The dental handpiece attachment includes a housing defining a dental handpiece receiving portion and a central portion. A receiving opening in the receiving portion is in fluid communication with a cavity in the central portion to receive a drive mechanism responsive to a dental handpiece. A rotatable prophy cup assembly having a passageway therethrough is disposed at a prophy paste dispensing opening of the central portion cavity to enable a given amount of prophy paste sufficient for a single application, and stored within the housing, to be dispensed through the passageway and applied to the teeth. An actuator mechanism disposed within the receiving portion cooperates with a dental handpiece to urge the stored prophy paste out of the housing when the handpiece is received within the receiving portion.
