Popis: Subject. Tobacco smoking is one of the risk factors of periodontal disease development; therefore, special attention should be paid to this group of patients in periodontal treatment management. Any pathological process in periodontium is directly or indirectly connected with microcirculatory disturbances. Therefore, the correction of these disturbances will promote the normalization of the periodontal morphofunctional status. Objectives. To study functional state of the microcirculatory channel system in the periodontal tissues of the young patients with different types of smoking. Matodology. Clinical examination of 240 patients was carried out with subsequent division into subgroups depending on the smoking type: smoking cigarettes, electronic cigarettes with liquids, tobacco heating systems and hookah with further division into subgroups depending on the smoking experience: up to 1 year, from 1 to 5 years, more than 5 years. Subsequently indices were determined: simplified index of oral hygiene according to Green–Vermillion (OHI-s, 1964), papillary-marginal-alveolar index (PMA modified by Parma, 1960), bleeding index SBI (Muehlemann modified by Cowell, 1975). For objective assessment of microcirculation in periodontal tissues we used high-frequency ultrasonic Dopplerography device "Minimax-Doppler-K" (LLC "SP-Minimax", St. Petersburg) with subsequent determination of average linear blood flow rate (Vas) and Gosling (PI) and Purcelo (RI) indices. Microcirculatory channel dynamics in periodontal tissues of the studied groups was studied in the state of physiological rest, immediately after smoking, in 15 minutes, in 30 minutes and in 60 minutes. Results. On the basis of the carried out research the distinctive indices of microcirculation in the periodontal tissues before and after different kinds of smoking as well as the functional state of the vascular architectonics were determined. Conclusions. The given research allows to understand at which types of smoking the smallest and the largest changes of microcirculation in periodontal tissues are observed and that also should be taken into account in daily clinical practice when seeing young periodontal patients who smoke.
