Abstract:

A dental light reflector and visual-audio analgesic assembly having a housing including a display screen upon which a selected film is projected and/or displayed. A reflector device is mounted below the housing, and includes a reflector and interacting lamp to illuminate the area of the patient's mouth under operation by the dentist or dental assistant. The positioning of the reflector assembly with respect to the housing during normal dental procedures is such that the display screen is placed into the direct field of view of the patient without any light interference from the reflector. The film being displayed may include a soundtrack and earphones enabling the patient to listen to the soundtrack of the film. Storage means are provided along the top plate of the housing to store films for selection by the patient. The assembly including the housing and reflector device are mounted to a yoke which is transportable within a track for proper positioning of the assembly with respect to a patient seated in a dental chair.
