Physical reactions during oral surgery were measured in 111 patients who were normal, other wise than the presence of oral diseases, 24 patients with psychosomatic diseases and 53 patients with hypertension, and the results obtained were analyzed. Plethysmogram, GSR, systolic pressure, diastolic pressure, pulse rate and RPP were measured as parameters of physiscal reactions. Easy and precise recording and analysis of the data could be attained by using a polygraph connected to a personal computer. When physical reactions were determined through the parameters, the effects of mental stress, pain stress and epinephrin could be observed because pulse rates, GSR and systolic pressure greatly varied at the time of anesthesia and tooth extraction. In comparison with the normal group, the psychosomatic group showed a larger alteration of plethysmogram during tooth extraction and of systolic pressure during anesthesia, while no marked changes in plethysmograms were seen throughout the measurement period in the hypertensive group. In this group, systolic pressure was found to increase before operation, and during and after the application of local anesthesia, pulse rates also increased at tooth extraction and after operation. These findings suggested that the hypertensive group tended to show marked and persistent physical reactions.
