[Comparative study of long term result of auto- and allografts for keratinized gingiva restoration in vestibuloplasty area on the lower jaw].

The purpose of the study was to assess the changes in the width and quality of keratinized tissue created in the area of vestibuloplasty on the lower jaw. Preliminary results of the study showed that autotransplantation method allows creating proper buffer zone with the desired mucosa thickness and is particularly justified in cases of "washing board" effect. However, the method is technically more demanding and is more expensive and painfull for patients.

[Comparative study of bacterial flora in patients with chronic periodontal disease assessed by various microbiological methods (preliminary study)].

Periodontal pockets microflora features by aggressive and chronic periodontal disease were studied by means of polymerase chain reaction (PCR) and mass spectrometry. The study included 14 patients aged 25-70 years without somatic pathology. The pilot study has shown the high prevalence rate in obligate periodontal pathogens in periodontal pockets revealed by PCR diagnostics, at the same time mass spectrometry has revealed the presence of other pathogens which had not been primarily included into PRC diagnosis.

[Hemodynamic features assessment in submental and facial arteries in patients with early atherosclerotic disease of brachycephalic arteries].

By ultrasonicduplex scanning nature estimated haemodynamics in the arteriessubmentalis and facial of patients with early signs of atherosclerotic changes in the brakhiotsefalarteries and periodontal pathology of different stages - for perfection of prophylaxis of periodontal diseases by the means of investigation of prophylaxis vascular diseases. It was established, that influence of risk factors is more important than the age of patients.

[Computer capillaroscopy for periodontal microcirculation assessment in patients with early atherosclerotic lesions].

The study of gingival microvessels was carried out by means of computer capillaroscopy in patients with moderate periodontal disease and early symptoms of atherosclerosis of extracranial portions of cephalic arteries. The results proved the decreased density of the capillar network in the marginal gingiva, as well as of linear and volumetric blood flow velocities drop in the arterial and venular portions of capillaries in patients with periodontal diseases combined with early atherosclerosis.

[Endo-perio lesions prevalence and awareness of dentists about diagnostics and treatment].

Two hundreds and ninety eight patients were included in the study. Endo-perio lesions were revealed in 53 (17.78%) patients.
