In order to investigate stresses of dental patients in dental clinic by dental-analogous stimulations, we selected 23 women and 36 men who are students of dental college in D university. This experiment was performed to compare and analyze the changes of Galvanic skin resistance and heart rate by dental-analogous stimulations. In paired t-test of male group's GSR average, there were significant differences between sound and touch, and among pain and other stimulations. And in paired t-test of female group's GSR average, there were significant differences among pain and other stimulations. In paired t-test of male group's heart rate average, there were significant differences between vision and pain, and between touch and pain. And in paired t-test of female group's heart rate average, there were significant differences between smell and pain. In unpaired t-test of male and female group's GSR average, there were no significant differences in smell, sound, vision, touch, and pain. In unpaired t-test of male and female group's heart rate average, there were no significant differences in smell, sound, vision, touch, and pain. It seemed that stresses during dental treatment could be changed by surrounding circumstances and sex distinction.
