    Abstract:
    OBJECTIVE: to determine the severity of gingivitis in children with teeth formation disorders - residents of the ter-ritories contaminated with radionuclides as a result of Chornobyl Nuclear Power Plant (ChNPP) accident. MATERIALS AND METHODS: The object of the study is 1470 children aged 6-14 years with dental malformations, 528 amomg them are residents of areas contaminated with radionuclides as a result of the ChNPP with the identified types of disorders of teeth formation (DTF) (systemic enamel hypoplasia (SEH) and molar-incisor hypomineralization (MIH)), and different stages of the severity of gingivitis. RESULTS: Determining of the degree of severity of gingivitis in children with DTF indicates the presence of its lesion of a moderate degree of the severity with a prevalence in persons with SEH or MIH and chronic diseases of internal organs suffered after the ChNPP accident. CONCLUSIONS: In irradiated children with DTF, an average degree of severity of gingivitis was established (РМА = (43.03 ± 19.64) %, p > 0.001), which may be due to the effect of a complex of negative factors, in particular the influence of low doses of ionizing radiation, the peculiarities of the social status of the examined persons (imbalanced nutrition), unsatisfactory oral hygiene. In children suffered after the ChNPP accident with SEH, the indicators of the PMA index were reliable (p > 0.05) higher compared to individuals with MIH, which indicates a more pronounced degree of periodont damage. Revealed damage to periodont, in particular gingivitis, in children with DTF residents of the contaminated territories, probably caused by the action of a complex of negative environmental factors, in particular the influence of low doses of ionizing radiation, and the peculiarities of the social status of children, which requires a comprehensive approach to the prevention of complications of defects of hard tissues of the teeth.
