Лазерная допплеровская флоуметрия в диагностике воспалительных заболеваний пародонта

Abstract

Purpose. To do a comparative analysis of literature data and authors’ own findings on the microcirculation in periodontal tissue in healthy subjects and in patients using laser Doppler flowmetry (LDF) technique. Material and methods. 143 patients were taken into the study. 54 literature sources were analyzed. In the reviewed publications there were found basic concepts of LDF technique for diagnosing microcirculation in the periodontal tissue in healthy subjects and in patients. The authors also presented their own findings obtained after the prospective cohort examination of the oral cavity in 143 patients. Apparatus LAKK-02 and program 2.2.510.512 (LAZMA, Russia) were used in the study. The following parameters were assessed: average blood perfusion (M) in perfusion units (p.u.), mean-square oscillation deviation in blood flow - δ(p.u.), a variation coefficient of blood flow oscillations, Kv normalized by the energy of oscillatory process E 0 . Results and discussion. While analyzing literature data, we revealed a high level of publication activity in the diagnostic group and in the group with prevailing Fourier transformation as an estimation technique for the amplitude-frequency spectrum of blood flow oscillations. Conclusion. The applied pathophysiological approach for assessing microcirculatory disorders allows to establish the relationship between recorded parameters of the basal blood flow and parameters of active and passive microcirculation regulation.
