Abstract:
1. A prophy angle comprising: a housing that includes a paste chamber, a drive mechanism comprising a drive shaft configured for delivering mechanical energy to a rotatable head assembly provided at a distal end of the prophy angle housing, wherein the prophy angle also includes a housing tube configured to fit about at least a portion of the drive shaft of the drive mechanism; and a paste dispensing assembly within the housing, the paste dispensing assembly further comprising: whereby movement of the actuator causes distal movement of the push rod and the generally cylindrical plunger to direct paste in a distal direction when in use in the prophy angle, and whereby release of the actuator causes proximal movement of the pushrod by the spring, but not the generally cylindrical plunger, such that continued actuation of the actuator caused controlled quantities of paste to be delivered out of the prophy angle.
