    摘要: A periodontal cleaning device including a hollow housing having a handle member and a brush head member. The brush head includes a gear train reciprocally driven by a rack. The gear train includes at least one drive gear engageable by the rack which in turn drives a plurality of series interconnected driven gears. The drive gear includes one portion engaged by the rack and another portion engaged by an adjacent driven gear. An axial width of a gear portion of the drive gear is greater than the axial width of gear portions of the driven gears so that in operation, the rack does not engage the driven gears. The drive and driven gears each include a tuft holder by which bristles are removably held.
