MORPHO-FUNCTIONAL CHARACTERISTICS OF THE MICROCIRCULATORY BED IN DIFFERENT AREAS OF THE GINGIVA

Objective - to study blood microcirculation in different parts of the gingiva and to detect its individual-typological characteristics. Materials and methods. Using the methods of biomicroscopy and laser Doppler flowmetry (LDF), the state of microcirculation of blood in different areas of the gingiva was studied in 40 healthy young men aged 17-22 years. The registration of microcirculation was carried out in 24 points of the frontal and masticatory gingiva of the upper and lower jaws. The depth of blood vessel location was studied using histological methods on gingival samples. Results. Data were obtained on the depth and density of capillaries, structural features of the microvessels, and the intensity of tissue blood flow in different areas of the gingiva. With the increase of the distance from the mucogingival fold to gingival margin, the decrease in the density of the capillary networks was observed. Conclusions. Analysis of microcirculation at symmetrical points of the gingiva on the upper and lower jaws showed a low degree of asymmetry in healthy individuals. The predominant type of microcirculation in the gingiva in healthy subjects was the mesohaemic type (87 % of observations).
