[The suggestive control of the pain threshold in healthy teeth].

Changes in pain tolerance after administration of differently labelled placebos were studied by measuring the reaction time after a cold stimulus. Significant changes after placebo administration were observed in the morning as well as in the evening. These differed among placebos declared to be analgetics, hyperaesthetics and medications with no effect on pain. The time of day also influenced the results.
