A first optical fiberscope extends from the front end portion of the powerhead near the dental tool into the front end of the sleeve bearing adjacent to the front end of the connecting means. A thickened fiberscope abuts the rear end of the first fiberscope and extends rearward through the handpiece to a light source. Cavities, passages and pipes are provided in the sleeve bearing and connecting means in order to provide a smooth flow of compressed air, chip air, water and exhaust to or from the powerhead assembly while permitting the sleeve bearing and connecting means to rotate relative to each other about the longitudinal axis of the handpiece.
