SUMMARY
Introduction. The article is devoted to the study of the dentoalveolar system in the children with chronic generalized catarrhal gingivitis and chronic tonsillitis in history. The objective. On the basis of epidemiological monitoring establish the status of bite in children with chronic generalized catarrhal gingivitis and chronic tonsillitis, examine the prevalence and clinical types of the formed teeth anomalies and evaluate them in the state of oral hygiene. Examine the intensity of lipid peroxidation processes and antioxidant system in children, aged 8-15 y. o. with accumulation teeth relevant indicators in the oral fluid and determine their links with chronic inflammatory diseases in periodontal and pharynx. Materials and methods. 1238 children aged 8-15 y. o., dwellers of the city ofOdessa suffering from chronic generalized catarrhal gingivitis and chronic have been examined.Tonsillitis was determined in three age groups: 8-10 y. o. - a period of variable bite; 11-13 y. o. - the period of formation of permanent occlusion; 14-15 y. o. - the period of permanent occlusion. Diagnostics of dentoalveolar anomalies and deformations were carried out on the basis of clinical examination of the patients. Results. Conclusions. It was found that the combination of chronic generalized catarrhal gingivitis, chronic tonsillitis in combination with crowding of teeth causes a significant decrease in the activity of the main antioxidant enzymes in the oral fluid among the children of all age groups.
