One-year follow-up of 20 patients with radicular cysts and 16 ones with medium-severity chronic periodontitis demonstrated the efficacy of hydroxylapatite with collagen. Active formation of osseous tissue at the site of cysts, in the periodontal osseous pockets, and at the apexes of interdental septa was observed 6 to 7 months after the treatment.

A total of 444 patients with histologically verified cysts (radicular, residual, traumatic, keratocysts, follicular) and some cystic formations (ameloblastomas, osteoclastomas, myxomas) were examined by clinical and x-ray methods. X-ray signs of some cystic diseases of the mandible are analyzed, x-ray symptoms which help differentiate between individual nosologic entities are singled out.

Analysis of mandibular roentgenograms of 286 patients with odontogenic osteomyelitis has lead the authors to a conclusion on the predominance of diffuse forms of the condition with marked sequestration in the 30's and 40's. Currently hyperplastic osteomyelitis occurs in 12% of cases.

[A standardized x-ray examination of mandibular fractures]. / Standartizirovannoe rentgenologicheskoe issledovanie pri perelomakh nizhnei cheliusti.

Proceeding from an x-ray examination of 143 patients with mandibular fractures, the most informative methods and projections as well as the order of their use with account of the site of a fracture, were determined. The most informative method in all fracture sites was orthopantomography; panoramic roentgenography was indicated only in fractures of the frontal part. If panoramic tomography cannot be done, roentgenography or electroroentgenography in the frontal-nasal projection is recommended. If panoramic roentgenography cannot be done, extraoral roentgenography is indicated in the diagnosis of fractures of the frontal part of the mandible.
