ABSTRACT:
A dental instrument for viewing the lingual surface of dentition and also providing moisture control as a saliva ejector and serving as a tongue holder and support for a cheek retractor. The instrument includes a base wall on which is placed a mirror and a pair of laterally extending side walls which can be used as rest blocks for the teeth during the dental procedure. A channel is formed internally of the instrument with a plurality of aspirator holes in flow communication with the channel. Outlet ports are provided also in flow communication with the channel to which can be connected tubing from a suction source. The dental instrument is positioned in the mouth so as to span the mouth cavity rearwardly of the upper and lower dentition and is self holding so that it can reflect the lingual surface of the dentition without being held manually in place.
