Objective: The aim: To determine the degree of severity of the inflammatory process in periodontal tissues of children living in different ecological conditions.
Patients and methods: 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: 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.
Conclusion: Conclusions. It was found that with increasing age of the examined children decreases the percentage of chronic catarrhal gingivitis of moderate severity.
