In clinical practice, there are patients for whom traditional methods of treatment do not allow getting rid of a dental disease. Dental mask of underlying pathology may be a potential cause of this. The aim of the study was to study the features of the clinical course of dental manifestations of gastroesophageal reflux disease. Methods. The study group included 45 patients aged 20 to 50 years with complaints of pathological changes in the oral cavity that did not stop during the last month. The survey included a survey and clinical examination. The GerdQ questionnaire was used to verify gastrointestinal disorders. Results. It was found that 85% of the surveyed complained of a burning sensation behind the breastbone, the ingress of acidic contents into the oral cavity. 100% of the surveyed presented dental complaints. At the same time, the frequency of dental complaints was significantly higher compared to the frequency of complaints of esophageal symptoms. According to the results of the GerdQ questionnaire, the average score among the subjects was 11.0, which corresponds to the presence of gastroesophageal reflux disease. According to the results of the dental examination, 87% of the examined patients had pathological elements on the oral mucosa, and the pathological elements of aphthous and herpetic stomatitis were found significantly more often in patients with an exacerbation of gastroesophageal reflux disease (p<0.05). Desquamative glossitis was detected in 33% of the examined patients, benign migratory glossitis (“geographical” tongue) in 59% of patients, exfoliative cheilitis (dry form) in 70% of patients, angular cheilitis in 23% of patients. The pathology of hard dental tissues was represented by multiple carious lesions in 75% of patients and non-carious lesions in 53% of patients. Conclusions. Diseases of the oral mucosa and non-carious lesions accompany patients with gastrointestinal tract pathology in the form of gastroesophageal reflux disease.

The quality of atmospheric air in modern cities in many ways determines the health status of the population and is the leading etiological factor in the development of diseases, primarily children, the elderly, and people with chronic respiratory and cardiovascular diseases. We analyzed air quality for the period 2007-2017, incidence rates of respiratory system and calculated the hazard index.

Systemic biomarkers (i.e. biomarkers of functioning of cellular pathways) offer a broad spectrum of diagnostic capabilities. There are several approaches to using systemic biomarkers that derive from exact needs of a researcher or a clinical specialist. First, analyzing a multifunctional and multi-systemic pathway in circulating cells (e.g. leukocytes) allows to gather generalized information on functioning of the organism. Second, there are numerous pathways that, even still in circulating cells, allow to assess risks of developing or stage of development of numerous diseases, including the leaders of non-infection diseases mortality-cardiovascular diseases. Third, biopsy specimens can readily be used to assess the exact signaling type of a disease (especially cancer) thus helping in selecting the best treatment option. Due to unique properties of the human oxidative status pathways that are discussed in the present chapter, diagnostics specialists are now acquiring an allin-one toolbox for profiling and detecting almost any non-infectious and a broad range of infectious diseases. In addition to properties of the human oxidative status pathways opening these possibilities, this chapter considers exact systemic biomarkers deriving from this approach, reveals some examples of usage of the resulting diagnostic technology and provides instances of successful clinical application of the systemic biomarker approach.
