A prophy angle for storing prophy paste in a controlled releasable manner, the angle having a first drive mechanism comprising a drive shaft for delivering mechanical energy to a rotatable head assembly at a distal end of prophy angle and an independent second drive mechanism configured to deliver a controlled amount of paste from a chamber to the distal end of the prophy angle, the second drive mechanism comprising an index wheel engaging an actuator so that the wheel may be driven in a stepped rotational manner upon actuation of the actuator by the clinician.
