Abstract
A mouth prop and tongue retractor apparatus for use in dental procedures. The apparatus includes a handle rotatably mounted within a base. A ball joint on the base fits within a socket in a mouth prop to provide pivotal positional adjustment of the apparatus. An elongated aspirator tube extends through the handle and base, and is coupled to a tongue retractor. A suction aperture on the tongue retractor communicates with the aspirator tube and provides for saliva removal from a patient's mouth. Rotation of the handle provides extension adjustment for the aspirator tube and tongue retractor.
