Today, the most pressing issue in the social program of society is the state of health care of the younger generation, which outlines the future prospects for the development of the nation. Numerous studies by foreign and domestic researchers show that among the dental pathology of periodontal tissue among children in our country remain at a high level, despite the developed treatment regimens. It is known that gingivitis in childhood is often not diagnosed at an early stage of development, due to the absence or mild complaints and signs of the disease, which can lead to chronicity and transition from inflammatory to inflammatory-destructive In recent years in medicine for early diagnosis and prognosis simple, atraumatic, informative methods are used more often, which do not require expensive special equipment and at the same time are sensitive indicators for various diseases. In this regard, the study of the properties of oral fluid remains relevant. Purpose — to study the properties of oral fluid in adolescents with catarrhal gingivitis and chronic gastroduodenitis. Materials and methods. The properties of oral fluid (salivation rate, pH, and microcrystallization) were studied in 173 adolescents aged 12 to 18 years, which was divided into three groups: 86 adolescents with catarrhal gingivitis on the background of chronic gastroduodenitis were included in the main group, and 57 adolescents in the comparison group, gingivitis without somatic pathology and in the control group — 30 adolescents with healthy periodontal disease without somatic diseases. Results. The dependence of oral fluid properties in adolescents on the presence of inflammatory process in the gums and somatic disease was determined, namely in the adolescents of the main group the rate of salivation was 0.27±0.02 ml/min, in the adolescents of the comparison group 0.37±0.03 ml/min (p<0.01) — and in adolescents of the control group 0.49±0.01 ml/min (p<0.001). Determination of the pH of the oral fluid showed that the adolescents of the pH control group averaged 7.15±0.03, then the adolescents of the comparison group and the main group 1.1 times less, respectively 6.48±0.02 and 6.29±0.04 (p<0.001). Conclusions. Тhe study of oral fluid indicates a dependence of the indicators of the overall condition of the body, and dental status. In addition, indicators of oral fluid can serve as a prognostic test assessment of the mouth and course of somatic diseases, the effectiveness of treatment and to justify the prevention of catarrhal gingivitis in adolescents. In the main group revealed predominantly II and III type of microcrystallization in the comparison group — II type, much less individuals with type III and an increase in persons with І аnd II type in the control group, we identified all three types of microcrystallization, and was dominated by type II and greatly increased the number of persons with type І and decreased type III. The research was carried out in accordance with the principles of the Helsinki Declaration. The study protocol was approved by the Local Ethics Committee of these Institutes. The informed consent of the patient was obtained for conducting the studies. No conflict of interest was declared by the author. Key words: oral fluid, the speed of salivation, pH, microcrystallization, teenagers, catarrhal gingivitis, chronic gastroduodenitis.
