ABSTRACT:
A disposable dry field tongue guard for intra-oral placement during a dental procedure to remove saliva from around the lingual side of the lower arch while also constraining the tongue so that the tongue does not interfere with the procedure. The dry field tongue guard comprises an evacuation tube having an exterior end that connects to a suction source. The interior end of the tube fits into an aperture that is centrally located in a curvatured top wall of a tongue guard sheath. There is a cavity within the tongue guard sheath within which the interior tip end of the evacuation tube is located. Channels extend from this cavity downwardly and outwardly to the outer periphery of the tongue guard sheath. A tongue shield for fitting over the tongue is disposed beneath the tongue guard shield. The device is retained in place on a patient during a dental procedure by means of a chin blade that has a friction lock fit on the exterior end of the evacuation tube.
