CHANGED CHARACTERISTICS OF MICROVASCULAR BLOOD FLOW IN PARODONTIUM TISSUES UNDER SMOKING IMPACT
A study has been carried out of smoking impact on microcirculation state in capillaries of parodontium tissues with the help of the method of laser Doppler flowmetry. It has been detected that the increased microcirculation index, grade of differences in the microcirculation index and the reduced index of microcirculation effectiveness were typical for smokers, and they corresponded clinically to the initial stage of the inflammation process in parodontium (was proved by the values of the CPI index and the hygienic tests). Depression of the mechanisms of active modulation of tissue blood flow in parodontium in catarrhal gingivitis was accompanied by the increased compensatory role of passive modulation that was directed at unloading of veins of the microcirculatory channel.
