title: Changes in the capillary flow of gingiva due to the influence of some impulses.
abstract: 75 healthy men and women, aged from 20 to 45 years, were divided into five groups of 15 persons each. Na131I resorption halftime values from the examined area of the gingiva, pulse frequency as well as systolic and diastolic blood pressure were examined. Tests were carried out twice. One group served as a control group. During the second test emotional, light, sound or tactile impulses were applied to the other groups. The control group that was not exposed to any of the impulses investigated during the second examination showed no significant differences in values with any of the observed indices. Under the influence of emotional, sound or light impulses, a significant increase in pulse frequency as well as in systolic and diastolic blood pressure was noted. This suggested that both the one-minute volume and the peripheral resistance of the circulation system increased. Na131I resorption half-time values from the examined area of the gingiva significantly increased under the influence of emotional and sound impulse by 64%, of light impulse by 84% and of tactile impulse by 93%. This meant that the blood flow through the capillary gingival bed had significantly reduced due to the influence of these impulses. It is to assume that their long-term influence could contribute to the development of parodontopathies.
