Abstract
A dental syringe tip handpiece assembly includes a clear, plastic syringe tip mounted in an adaptor for connection to the handpiece. On the interior of the adaptor at a location adjacent the end of the syringe tip, a source of light is provided. Light from the light source will be transmitted down the length of the syringe tip and emitted from the end thereof. By positioning the end of the syringe tip in the patient's oral cavity, the dentist can provide illumination in the oral cavity so that various dental functions can be more easily and accurately performed. The adaptor can be made from clear, or at least translucent, material so that light from the light bulb will be transmitted through the adaptor and then into the syringe tip. A slot is provided on one end of the syringe tip for keying the syringe tip into the adaptor to properly align the syringe tip in the adaptor.
