ABSTRACT:
The present invention comprises an improved oral self inspection device that is versatile, inexpensive, and easy to use. The device consists of a small, cylindrical light source on which a small front primary or inspection mirror, a larger rear secondary or ocular mirror, and a cheek and tongue extender are mounted. Each of these implements is mounted at the end of an arm whose other end is rotatably and slideably mounted on the cylindrical light source. Each such arm is independently rotatable a full 360 degrees around the body of the cylindrical light source, such that the relative angular position between each of the implements is infinitely variable. Each of the arms is also independently slideable along the cylindrical light source, such that the relative separation between the implements can also be readily changed. The primary mirror may be attached to its mounting arm at a fixed angle, or the angle of tilt may be adjustable. The secondary mirror is mounted to its arm by means of a universal ball joint such that its angular orientation can be easily changed. The secondary mirror consists of a concave mirror on one side and a flat mirror on the other side to allow both magnified and unmagnified viewing of the image reflected by the primary mirror. The tongue and cheek extender consists of a resilient arm having a flat enlarged portion at one end which can be positioned adjacent the primary mirror such that it maintains a person's cheek or tongue to one side of the primary mirror and a clear line of sight from the secondary mirror to the primary mirror is maintained.
