SUMMARY
Objective. Not only the harmful effects of passive smoking on open mucosal surfaces, but also the ability to develop various diseases and reduce the immune barrier functions of the body, is a relevant study on passive smoking among children, causing various nosoforms of dental morbidity, which has not yet been conducted in our country in sufficient volume, which is the purpose of this study. Material and methods. By examining anthropometric indicators, it is possible to assess the physical development of the child's body and its compliance with age norms. The identified deviations can be risk factors or signs of some diseases. We decided to determine the measurements of height, weight and chest volume in five secondary schools in Baku using the questionnaire method. Simultaneously with the questionnaire, we examined the outpatient cards of schoolchildren in regional clinics. Results and discussion. According to the data of the fully completed questionnaires, the examined group of schoolchildren sought dental care 2950 times, of which 1050 visits were single, 450 visits were 2-fold, 240 visits were 3-fold, and 70 visits were 4-fold. All 4-fold visits were identified among schoolchildren exposed to passive smoking. Conclusions. Children without sufficient attention from adults are more susceptible to tobacco addiction, spending a lot of time in the company of smoking peers, which leads to such risk factors as obesity, poor nutrition, and mental health disorders. World experience shows that many common forms of diseases in school-age children can be effectively, simply, and inexpensively dealt with by implementing school programs related to health protection and promotion and rational nutrition.
