Summary:

Objective: to determine the relationship of microcirculatory changes in general blood flow and periodontal tissues in pregnant women. Material and methods. 98 pregnant women participated in the examination, who underwent an analysis of microcirculatory changes in the fourth finger of the left hand and periodontal. The control group consisted of 30 non-pregnant women. Laser Doppler flowmetric examination was carried out in two stages. At the 1st stage, the vasomotor activity of blood vessels was studied, at the 2nd stage — the contribution of high- and low-frequency oscillations to the overall modulation of blood flow. A correlation analysis of microcirculatory changes in general blood flow and periodontal disease was performed. Results. In pregnant women, there is a decrease in vasomotor activity of blood vessels, a deterioration in the rate of local blood flow. The coefficient of variation is 1.6 times less than the same value obtained in the control group. The percentage of contribution of pulse and respiratory waves is 7.6 times and 1.5 times higher relative to the control group, in the modulation spectrum of which the amplitude of myogenic genesis prevailed. A functional relationship was found between the rate of local blood flow of the microvessels of the oral cavity and the vasomotor activity of the fourth finger of the left hand (Pearson coefficient 1.0). Conclusion. The revealed relationship testifies and confirms the uniformity of changes in microcirculatory disorders both in periodontal tissues and in the general blood flow of the body as a whole. This fact should be taken into account when managing pregnant women by a dentist and a gynecologist.

Keywords: laser Doppler floumetry, microcirculatory changes in general blood flow, microcirculatory changes in periodontal disease
