Radiation-induced pathology of the tissues of the oralcavity.

It is noted that the presence of neglected and long-term untreated periodontitis can lead not only to the aggravation of dental problems, in the form of complicated caries, loss and loss of teeth, but also to an increased risk of gastrointestinal diseases and diseases of the cardiovascular system. [1] It should be recognized that the literature data on post-traditional changes in the oral mucosa are generally sporadic. Thus, in the publications of Belarusian scientists after the accident at the Chernobyl nuclear power plant, frequent lesions of the mucous membrane in the form of dryness, swelling, and hyperemia were reported. The same study reported a high incidence of caries compared to control areas. In addition, the authors noted an increased incidence of aphthous stomatitis and recurrent herpes in the exposed population. [2] The work of other researchers noted an increase in the incidence of periodontal diseases in the population of Belarus, especially in areas affected by the Chernobyl accident. [3] In the region of the Semipalatinsk nuclear test site, dental morbidity in children and adults was also studied. The most extensive comprehensive examination of the affected population of the Semipalatinsk region with the study of the course, treatment and prevention of periodontal and oral mucosa diseases is given, where it is convincingly shown that in the mechanism of development of oral mucosa candidiasis and chronic recurrent aphthous stomatitis, the leading role belongs to changes in immune parameters, salivary dysfunction and microcirculation disorders...
