The aim: To determine the degree of severity of the inflammatory process in periodontal tissues of
children living in different ecological conditions.
Materials and methods: With the purpose of estimation of the condition of periodontal tissues the
epidemiology examination of 642 children that live on territory with the high level of pollution and
natural deficit of iodine and fluorine was conducted.
Results: The study found that the increase of age of examined children causes the decrease of
percentage of easy degree of severity of chronic catarrhal gingivitis, giving way to the advanced
forms of the disease, and this process was more pronounced in children living in ecologically polluted
region. In children-inhabitants of ecologically clean region easy degree of severity of chronic
catarrhal gingivitis met more often than their peers living in environmentally polluted region. At the
same time, average and heavy degree of severity of chronic catarrhal gingivitis in children living in
ecologically contaminated region met more often than their peers, inhabitants of ecologically clean
region.
Conclusions. It was found that with increasing age of the examined children decreases the
percentage of chronic catarrhal gingivitis of moderate severity.
