ABSTRACT:
A face mask for occupying the senses of a dental patient during dental work has an interior surface positioned to be viewed by the patient. A fiber optic bundle is carried at one end on the viewing surface and at its other end is butted against the front of a cathode ray tube driven by the video output signal from an audio-visual program source. The mask carries earphones fed by the audio output of the source.
