Abstract: A light is built directly into a scaler hand piece and adds little or no additional bulk or weight thereto. The light allows a Veterinarian or Technician to directly illuminate an area to be worked, with the hand piece providing a bright, clear source of light with no shadows. The light can be emitted from a light tube disposed along a scaler insert device, providing emission of light near the tip of the scaler insert. The light can be easily placed directly into a patient's oral cavity. With the light built into the scaler, it does not add any additional bulk and the scaler hand piece and light source can be easily directed to the area that requires work. The light source, being mounted directly into the scaler hand piece, is more cost efficient compared to purchasing a separate external light source to be affixed to the scaler hand piece.

Abstract: A micro-motor hand piece solves the problem of a lack of directly focused light in a patient's oral cavity when polishing a patient's teeth or performing dentistry. The source of illumination is built directly into the nose of the micro-motor hand piece to flood the area around the working tip of the micro-motor hand piece with light. The light is automatically focused in the area in which the Veterinarian or Technician is working, without casting any shadows in the area undergoing the procedure. The light can be from, for example, three light emitting diodes (LEDs), or some other light source, such as a fiber optic light source, incorporated directly into the nose of the micro motor hand piece.
