[The indications for the surgical treatment of chronic periodontitis of the permanent teeth in children and adolescents of different health groups].

Chronic granulating and granulomatous periodontitis of 250 permanent teeth was treated in children and adolescents aged 7 to 17, surgery had to be resorted to in 44 (18%) cases. Three groups of indications for radical treatment of chronic periodontitis in children were distinguished: difficulties in or impossibility of conservative treatment, inefficacy of conservative treatment, and somatic indications. The conservative and surgical methods together are most often indicated for patients in whom the adverse conditions of treatment (the first group of indications) are associated with an aggravated somatic status. Radical methods of treatment helped attain bone tissue recovery sooner (in 5-6 months) than after conservative therapy alone (in 8-9 months) and completely liquidate chronic foci of odontogenic infection.
