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, preferably a fiberoptic ringlight, 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 source of light may also be a light bulb positioned at the rear of the adaptor. The adaptor is 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 special handpiece body formed of a handpiece inner unit and an outer cover is provided to receive the adaptor and syringe tip assembly. The air, water and fiberoptic lines are positioned inside the handpiece body. The handpiece body can be easily disassembled for cleaning.
