У водолазов при спуске под воду могут возникать приступы острой зубной боли (бароденталгии), которая создает аварийную ситуацию и ведет к прекращению водолазного спуска. Бароденталгия может быть обусловлена гипоксическим процессом в пульпе пломбированных зубов и повышением внутрипульпарного давления.</p></sec><sec><title>Цель</title><p>Цель. На основании изменений показателей (оксиметрии и флуоресценции) выявить особенности протекания гипоксических процессов в пульпе пломбированных зубов при гипербарическом воздействии.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследовании приняли участие 34 водолаза из числа лиц мужского пола. На первом этапе было проведено их стоматологическое обследование с целью отбора претендентов на второй этап эксперимента. На второй этап отобрано 24 испытуемых, у которых проведена оценка оксиметрических (сатурация смешанной крови) и флуоресцентных (восстановленный кофермент НАДН, окисленный кофермент ФАД, флуоресцентный показатель потребления кислорода — ФПК) показателей пломбированных зубов. Оценку проводили методами оптической тканевой оксиметрии (ОТО) и лазерной флуоресцентной диагностики (ЛДФ) до и после погружения в барокамере при давлении 0,4 МПа при дыхании воздухом.</p></sec><sec><title>Результаты</title><p>Результаты. После воздействия повышенного давления газовой среды по сравнению с исходными значениями в пломбированных зубах наблюдалось: снижение сатурации пульпы на 33,7% (р &lt; 0,05); увеличение НАДH на 14,4%; снижение ФАД на 22,9%; повышение ФПК на 73,4% (р &lt; 0,05).</p></sec><sec><title>Выводы</title><p>Выводы. Выявленные изменения показателей сатурации смешанной крови, НАДН, ФАД и ФПК подтверждают наличие гипоксического процесса в пульпе пломбированных зубов при гипербарическом воздействии.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. During their descent under water, divers may suffer from acute toothache attacks (barodentalgia), creating an emergency that leads to the termination of diving descent. Barodentalgia can be caused by hypoxic process in the pulp of filled teeth under increased intrapulpal pressure.</p></sec><sec><title>Objective</title><p>Objective. To reveal the peculiarities of hypoxic processes in the pulp of filled teeth under hyperbaric exposure basing on oximetry and fluorescence change parameters.</p></sec><sec><title>Мaterials and methods</title><p>Мaterials and methods. The study involved 34 male divers who underwent a dental examination at the first stage to select individuals for the second stage of the experiment. 24 subjects were selected for the second stage and evaluated for oximetric (mixed blood saturation) and fluorescent (reduced coenzyme NADH, oxidized coenzyme FAD, fluorescent oxygen consumption index — FOCI) indices of filled teeth. The evaluation was performed by optical tissue oximetry (OTO) and laser-induced fluorescence (LIF) methods before and after immersion in a barocamera at pressure of 0.4 MPa while breathing air.</p></sec><sec><title>Results</title><p>Results. Following exposure to increased pressure of the gas medium as compared to the initial values in the filled teeth, the following phenomena were observed: decrease in pulp saturation by 33.7% (p&lt;0.05); increase in NADH by 14.4%; decrease in FAD by 22.9%; increase in FOD by 73.4% (p&lt;0.05).</p></sec><sec><title>Conclusions</title><p>Conclusions. The revealed changes in the indicators of mixed blood saturation, NADH, FAD and FOCI confirm the presence of hypoxic process in the pulp of filled teeth under hyperbaric exposure.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>зубная боль</kwd><kwd>стоматология</kwd><kwd>бароденталгия</kwd><kwd>водолазы</kwd><kwd>гипоксия</kwd><kwd>сатурация</kwd><kwd>пломбированные зубы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>toothache</kwd><kwd>dentistry</kwd><kwd>barodentalgia</kwd><kwd>divers</kwd><kwd>hypoxia</kwd><kwd>saturation</kwd><kwd>filled teeth</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Благодарности: профессору Борисовой Элеоноре Геннадиевне и доценту Ковалевскому Александру Мечиславовичу из Военно-медицинской академии за ценные критические замечания.</funding-statement><funding-statement xml:lang="en">Acknowledgements: the authors would like to express their gratitude to Professor Eleonora G.
