ABSTRACT:
This device uses a piezoelectric crystal for converting electrical energy into mechanical vibrations which are transmitted to a dental workpiece for use in cleaning teeth. The device includes a front cap having flats which engage flats on the tip base attached to the dental workpiece and allows dental workpieces to be interchanged. The device includes a tie rod disposed within the tubular crystal around which water circulates between the tie rod and the tubular crystal. Axial bores allow passage of the water to the tip of the workpiece to wash away debris on the teeth during cleaning.
