title: Relaxation effect of an audiovisual system on dental patients. Part 2. Palus-amplitude.
abstract: Dental care services include relaxation of patients to reduce their displeasure at and tension during treatment. For this purpose, it is common to use audio or audiovisual programs, that is, to let them listen to music or watch TV. However, the former utilizes only the auditory sense, and the latter is disadvantageous in that a TV set is a rather large-scale unit. In the present study, we determined the relaxation effect of an audiovisual instrument on dental patients. The instrument, which gives virtual vision, was composed of a lightweight eyeset of the snow goggle type that has a built-in TV screen, with earphone and accessories. The relaxation effect was determined using a polygraph.
