The relationship between microcirculatory changes in general blood flow and periodontium in pregnant women

Objective: to identify the relationship between microcirculatory changes in the general blood flow and periodontium in pregnant women. Materials and Methods. The study involved 98 pregnant women who were examined for microcirculatory changes in the fourth finger of the left hand and periodontium. The control group consisted of 30 nonpregnant women. Laser Doppler flowmetry was carried out in two stages. At stage 1, vasomotor activity of vessels was studied, while at stage 2, the contribution of high- and low-frequency oscillations to the overall modulation of blood flow was examined. A correlation analysis of microcirculatory changes in the general blood flow and periodontium was performed. Results. Pregnant women exhibited a reduction in vasomotor activity of vessels and a deterioration in the local blood flow rate. The coefficient of variation was 1.6 times smaller than in the control group (p=0.03). The percentages of the contribution of pulse and respiration waveforms were 7.6 (p=0.03) and 1.5 times (p=0.03) higher than in the control group, in the modulation spectrum of which the amplitude of myogenic genesis prevailed. We revealed a functional relationship between the local blood flow rate in the oral cavity microvessels and the vasomotor activity of the fourth finger of the left hand (Pearson correlation coefficient: 1.0). Conclusion. The revealed relationship confirms the homogeneity of changes in microcirculatory disorder both in periodontium and in the general blood flow in the entire body. This fact must be taken into account when managing pregnant women by a dentist and a gynecologist.
