ABSTRACT:
For a dentist's installation comprising a handpiece equipped with a turbine for driving a dental tool and flexible conduits leading to the handpiece to supply pressure fluid for driving the turbine, leading turbine exhaust fluid away from the handpiece, and supplying at least cooling water to be applied to the tooth, the invention provides an improved swivel arrangement effective to prevent forces from being applied by the flexible hoses to the handpiece. A face seal swivel is employed in a manner eliminating compression seals, such as gaskets or O-rings. In addition to passing fluids, the device can transmit light via the swivel so that the dental tool and tooth can be illuminated.
