Abstract: A needle burner apparatus is a generally rectangular box with a needle alignment plate located under the cover thereof. The interior of the box is provided with the electrode assembly, the drive assembly for horizontally rotating and horizontally reciprocating the electrode, the exhaust fan assembly and the container for collecting burned needle residue. The needle alignment plate is mounted to the underside of the cover of the box and is spring-biased upwardly. The electrode is a single rod element that is positioned horizontally in a carriage. The rod electrode is mounted for rotation along its horizontal axis and the carriage is also mounted for horizontal reciprocal motion. A drive motor effect the axial rotation of the electrode and, through a gearing assembly, the same drive motor also effects the horizontal reciprocal motion of the carriage.

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.

Abstract: A dental suction tool has a disposable sanitary plastic suction tip to prevent cross contamination from one patient to the next. The suction tip is formed as a generally cylindrical hollow tubing and made of disposable plastic material. One end of the suction tip has at least one beveled section along an outer wall surface of the suction tip so that the suction tip can be properly aligned in the dental suction tool. Alternatively, one end of the suction tip has at least one recess that is adapted to cooperate with a keying element in the dental suction tool to properly align the suction tip in the dental suction tool.

Abstract: A dental suction tool has a disposable sanitary plastic suction tip to prevent cross contamination from one patient to the next. Additionally, a light source such as a fiberoptic bundle with or without a ring light is provided on the interior of the dental suction tool to provide light to the end of the plastic disposable suction tip. Illumination from the ring light or directly from the fiberoptic bundle is transmitted along the length of the suction tip and is emitted from the end thereof to illuminate the oral cavity during dental procedures.
