Such investigations are constrained, nevertheless, by the potential impact of several variables on the concentration of the elements.</p> <p><bold><italic>AIM:</italic></bold> To study the influence of individual and subpopulation factors of donors on the concentration of some major and trace elements in saliva.</p> <p><bold><italic>MATERIALS AND METHODS:</italic></bold> The results of the determination of elements concentration (Ag, Al, Ca, Cd, Cr, Cu, Fe, Mg, Mn, P, Pb, Si, Ti, Zn) in the whole saliva of 60 donors by direct (without digestion) analysis by arc atomic emission spectrometry using the dry residue technique are presented.</p> <p><bold><italic>RESULTS:</italic></bold> Distribution of concentrations in the sample for Al, Cr, Cu, Fe, Mg, Mn, Si, Ti, and Zn showed a lognormal law; thus, the geometric mean or median is preferable as an indicator reflecting the average value. The distribution of Ca and P concentrations obeys the normal law. The concentration of Si and Ti is lower in the saliva of young men compared with women; the opposite pattern is observed for Mn. The mean Ag concentration in saliva is higher in the group of smokers than in non-smokers. Increase in the number of teeth affected by caries was correlated with an increase in concentrations of Cu, Al, and Zn in the saliva. For several analytes, interelement correlations were revealed, in particular, between the concentrations of Ca and P.</p> <p><bold><italic>CONCLUSION:</italic></bold> The study of such factors of influence enables clinicians to determine the normal concentration ranges of major and trace elements in each specific clinical case with greater accuracy.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Определение макро- и микроэлементного состава слюны может быть перспективным подходом для неинвазивного мониторинга состояния здоровья. Однако возможное влияние ряда факторов на концентрацию элементов ограничивает подобные исследования.</p> <p><bold>Цель.</bold> Изучение влияния индивидуальных и субпопуляционных факторов доноров на концентрацию ряда макро- и микроэлементов в слюне.</p> <p><bold>Материалы и методы.</bold> Представлены результаты определения концентрации элементов (Ag, Al, Ca, Cd, Cr, Cu, Fe, Mg, Mn, P, Pb, Si, Ti, Zn) в цельной слюне 60 доноров путём прямого (без минерализации) анализа методом дуговой атомно-эмиссионной спектрометрии по способу сухого остатка.</p> <p><bold>Результаты.</bold> Распределение концентраций в выборке проб для Al, Cr, Cu, Fe, Mg, Mn, Si, Ti, Zn подчиняется логнормальному закону; в качестве показателя, отражающего среднее значение для массива проб, предпочтительно среднее геометрическое или медиана. Распределение концентраций Ca и P подчиняется нормальному закону. Содержание Si и Ti ниже в слюне молодых людей по сравнению с девушками, для Mn наблюдается обратная закономерность. Средняя концентрация Ag выше в группе курящих доноров по сравнению с некурящими. Увеличение количества зубов, поражённых кариесом, коррелирует с повышенными концентрациями Cu, Al и Zn в слюне. Для ряда аналитов выявлены межэлементные корреляции, в частности между концентрациями Ca и P.</p> <p><bold>Заключение.</bold> Изучение факторов влияния позволяет более корректно определять нормальные диапазоны концентраций макро- и микроэлементов в слюне в каждом конкретном клиническом случае.</p></trans-abstract><kwd-group xml:lang="en"><kwd>saliva</kwd><kwd>trace elements</kwd><kwd>major elements</kwd><kwd>subpopulation factors</kwd><kwd>average concentrations</kwd><kwd>gender</kwd><kwd>dental fillings</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>слюна</kwd><kwd>микроэлементы</kwd><kwd>макроэлементы</kwd><kwd>субпопуляционные факторы</kwd><kwd>средние концентрации</kwd><kwd>пол</kwd><kwd>пломбы в зубах</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Грант Президента РФ</institution></institution-wrap><institution-wrap><institution xml:lang="en">Grant of the President of the Russian Federation</institution></institution-wrap></funding-source><award-id>МК-2476.2021.1.3</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Avcyn AP, Zhavoronkov AA, Rish MA, Strochkova LS.
