Hydroxyapol, hapcol and colapol were used to repair the postoperative defects in the jaws in 83 patients of different sex and age. Ossification of bone cavities was more rapid and complete than in the reference group. Complications observed in 7 patients resulted from strategic or technological errors.
The authors view results of conservative and surgical treatment of constant tooth chronic periodontitis in 90 children and adolescents aged 7-18 20 hemisections, 45 apicoectomies, 10 radix amputations were performed. The patients were followed up 6 months to 5 years. X-ray films show osseous restoration on the maxilla tooth to complete in 5-6 months, on the mandible tooth in over 8 months. The authors describe indications and contraindications to such kind.
The authors review clinical and X-ray examinations of 30 patients with keratocysts and show difficulties of differential diagnosis with other cysts. Keratocysts are aggressive and prone to recurrences. The authors disclose some clinico-radiological, macroscopic and histological features of keratocysts which may be helpful in valid diagnosis making.
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.
A high incidence of complications developing during and after removal of teeth with chronic periodontitis and radicular cysts has made the dentists resort to conservative surgical methods of treatment of such conditions. These methods are replantation, resection of radical apex, hemisection, radicular amputation, granulectomy, crown-radicular separation, crown-radicular amputation, hemireplantation, and inter-radicular granulectomy. The technique of such treatment is described in detail. Conservative surgical methods of treatment include the following stages: (1) conservative therapy; (2) surgical treatment; (3) orthodontic treatment; (4) dynamic follow-up till complete recovery of osseous tissue. The recommended modalities are not difficult but rather effective and may be performed at pedodontic clinics.
