The authors conducted two series of animal experiments. In the control series, reparative regeneration in the alveolar sockets of extracted teeth went under the blood clot. In the main series, the socket was replaced by a collagen-apatite composite. After histological preparations were studied, it was demonstrated that the process of reparative regeneration was much more intensive in the series with the collagen-apatite composite

Chronic inflammatory processes in periodontal tissues are accompanied by an abrupt increase in the levels of interleukin-1b, tumor necrosis factor-α, annexin V, matrix-metalloproteinase-1 proenzyme, tissue inhibitor of matrix-metalloproteinase-1 (TIMP-1), the activity of lactatdehydrogenase, aspartataminotranspherase, alaninaminotranspherase, supeoxiddismutase, and some increase in the content of α-defensins in mixed saliva. An acute form of inflammation is characterized by an increased activity of supeoxiddismutase and aspartataminotranspherase, interleikin-6, matrix-metalloproteinase-1 proenzyme accompanied by a significant decrease in TIMP-1 in mixed saliva

The article describes 3 groups of biopsy samples obtained from 74 patients with chronic periodontitis before and after a basic anti-inflammatory course (Group 1: active inflammation; Group 2: minimal inflammation; Group 3: "stationary" stage of inflammation). In 28 (37.8%) patients minimal inflammation remained in gingival biopsy samples at the end of treatment, while their clinical indices were normal, which indicated an unfavorable outcome of treatment. Retrospective analysis of the results of clinical examination in groups with a favorable and unfavorable outcome of treatment revealed significant differences between the groups. In the group with an unfavorable outcome mean age was 46.8±11.64 years, the duration of the disease was 10 years or more, Fuchs OI was 59%, Russell's PI index was more than 5.27, and the depth of periodontal pockets was 4 mm or more; these indices were statistically higher than the same ones in the group with a favorable outcome. These data can be used to predict the outcome of anti-inflammatory treatment.

In order to reveal correlations between parental smoking and the incidence of temporary teeth caries in children, 309 3-year-old children were examined. According to the study, maternal smoking, paternal smoking, maternal pregnancy smoking, and passive child smoking are risk factors of temporary teeth caries. The highest intensity of temporary teeth surface caries was revealed in children whose mothers smoked during pregnancy and still smoke.

The study demonstrated that the use of narrow-spectrum infrared rays in complex treatment of a septic wound of acute odontogenic mandibular osteomyelitis in children led to complete elimination of pathogenic and conditionally pathogenic bacteria by day 7 or 8, improved the patients' condition in general, and diminished local clinical signs of an acute process

A case of a blunt bullet facial wound is described. It was impossible to remove the bullet from the mouth floor wound, so the surgical approach was performed from the submandibular area using an X-ray image-converter tube, which made the surgery significantly simpler

The authors present a differential diagnostic system of salivary gland pathology. The mathematic model and program algorithm were developed by an original method of symptom processing and interpretation. High accuracy of the program was proved by testing under clinical conditions. The authors recommend that the program be used in clinical practice. The mathematic modeling method may be used to create intelligent expert software in other areas of medicine
