The present invention relates to a powered toothbrush with two moving bristle bearing parts, the first such part is disc-shaped and rotates or oscillates back-and-forth, the second such part is coupled to the brush head by an elastomeric material, such that the second section can be moved either by the force of brushing or by selective engagement with the drive mechanism of the toothbrush. The slurries of the present invention resist gel formation. The programmable device examines the pairs of strobe reading made around each of the different bit positions to determine whether or not a bit transition has occurred there. Embodiments then generate an index or menu based on individual consumer preferences. The controller further commands the actuator to couple the selected subset of the plungers to the power end.
