Results of tribological tests of samples of dental materials with protective coating of silicon carbide known as "Pantsyr"
Abstract
Tribology tests of standards in the conditions of the Proof-of-concept laboratory of functional surfaces covered and uncovered by sheeting «Pantsyr» from the carbide of silicon was conducted by the method of the measuring skidding on the automated machine offriction(tribometer) of TRIBOMETER of firm CSM Instruments. The results of tribology tests treated by means of the computer program Instrum X (CSM Instruments, Switzerland). Profilometric research offurrows of wear on separate standards with coverage and without him with the purpose of determination of area of section offurrows for a subsequent calculation the brought wear over of standards conducted on the optical profilometer of WYKO NT1100 firm Veeco(THE USA), Among studied it is necessary to distinguish a with coverage (Plastic(Ftoraks)), that at the indicated terms of tests showed very subzero(less than 0,1) constant of friction at his insignificant amplitude. It testifies to set constant of friction that did not almost change during all experiment (15000 cycles equal to the year of the use ofprosthetic appliance a patient For (Plastic (Ftoraks)), the brought wear over, that made 9*10 -6мм 3/(Н*м) The same standard without coverage showed a wear more than twice higher ((1.4-0,9)/0.9), was expected.

Research of dynamics of an atrophy of a bone tissue at orthopedic treatment of patients with total loss of teeth with use the dental implants
Abstract
Results of studying of dynamics of an atrophy of an alveolar bone of a prosthetic field at the patients who finished orthopedic treatment with use of the full removable artificial limbs leaning on dental implants of various diameter are reflected in article. Dynamics ofa resorption of a bone tissue was estimated within 5 years in 2 groups ofpatients: at patients with dental implants of standard diameter, and with dental miniimplants in different terms from the moment of fixing of constant orthopedic designs. As a result of the analysis of radiological researches studying ofdynamics ofa resorption of level ofa bone tissue in necks of the implants used for a support of a full removable artificial limb was carried out. The comparative assessment of these indicators on the basis of which conclusions about loudspeakers of indicators of an atrophy of a bone tissue in area the dental implants at this category ofpatients were formulated is carried out and the corresponding recommendations for practice are made.

Evaluation of anti-inflammatory effects of the herbal mouthrinses in gingivitis treatment in adults with teeth crowding
Abstract
In order to assess efficacy "Stomatofit" and "Stomatofit Fresh" in the treatment of gingivitis in patients with crowding a randomized controlled clinical trial was performed. 60 patients were divided into 3 groups. In group 1 in the treatment protocol was included mouthrinse "Stomatofit" within 10 days and mouthrinse "StomatofitFresh" for 28 days. Group 2 used 0.05% chlorhexidine bigluconate for 10 days. In group 3, the use of antiseptic mouthwash was not recommended. Prior to treatment the mean values determined by hygienic and periodontal indices: Silness-Loe plaque index - 2,2 ± 0,3, Tureski modified quigleyhein plaque index - 2,5 ± 0,5, PMA (Parma) - 39% ± 6%, index GBP (Muhlemann) - 2,1 ± 0,3 . After 10 days after treatment in group 1 a marked improvement: Silness-Loe - 0,5 ± 0,1, Tureski - 0,5 ± 0,1, PMA - 6% ± 2%, GBP - 0,3 ± 0.1. In Group 2, the following values: Silness-Loe - 0,4 ± 0,1, Tureski - 0,6 ± 0,2, PMA - 5 ± 2%, GBP - 0,2 ± 0,1. No significant difference between the groups 1 and 2 was identified. In Group 3, the results were significantly worse than in groups 1 and 2: Silness-Loe - 1,0 ± 0,2, Tureski - 1,3 ± 0,3, PMA - 11% ± 3%, GBP - 0.8 ± 0.3. After 28 days in groups 2 and 3, there was an increase of plaque and periodontal index values. In group 1 patients used mouthrinse "Stomatofit Fresh" twice a day, and the studied indexes remained at a low level. Thus, the use of herbal mouthrinses improves the treatment ofgingivitis and ensures consistent clinical results.

Results of a 10-year retrospective analysis of treatment of chronic periodontitis
Abstract
In article the result of 10 years’ supervision of205 teeth at 159 patients to whom carried out endodontichesky treatment of chronic periodontitis is analysed. During the observed period prosthetics of 95 teeth was made. As a result of prosthetics of teeth in terms till 10 years complications - changes, perforation of roots and a bottom ofa cavity of tooth, okklyuzionny injuries which led to removal in 25 cases and, as a result, to repeated prosthetics were revealed.

Evaluation of the standard provision of endodontic care for diseases of the periodontium of the tooth
Abstract
A clinical and radiological study to assess the standard of rendering assistance in the endodontic tooth periodontal disease. A total of 104 people (85 men and 19 women) aged 18 to 55 years who underwent endodontic treatment of teeth on the various forms ofperiodontitis. It is found that the standard endodontic and periodontal single rooted teeth multirooted performed respectively in the formation of the access to the cavity of a tooth in 86.67% and 87.64% of cases; forming the mouth of the root canal - to 80.0% and 83.9% of cases; measuring the working length - in 80.0% and 78.65% of the cases; Root formation channel (s) of the tooth - at 86.67% and 84.27% of cases; homogeneity and its (their) obturation filling material is provided in 80.0% and 89.89% of cases. Satisfactory root canalfilling servicemen to complete endodontic treatment ofperiodontitis single rooted, two or three teeth of the root is determined, respectively, 73.33%, 69.23 and 66.67% of cases.

Clinical characteristics of different variants of acute odontogenic inflammatory diseases
Abstract
In all clinical variants acute odontogenic inflammatory diseases showed signs of regional lymphadenitis. When periostitis in the process involves mainly submandibular, buccal, and much less parotid lymph nodes. The inflammatory process got involved in osteomyelitis preferably from 2 to 4 lymph nodes, whereas in phlegmon virtually all patients develop lymphadenopathy all regional lymph nodes. Investigation of the chewing muscles depended largely on how the severity of the current acute odontogenic inflammatory diseases and on the possible location of the most significant was manifested when phlegmons. The study indicates that the soft tissue syndrome maxillofacial area at various clinical variants acute odontogenic inflammatory diseases quantitatively measured at periostitis and osteomyelitis was Grade II, with flegmona - III degree of damage.

Effect of splinting of teeth in patients with chronic generalized periodontitis on the dynamics of the immunological parameters of oral fluid
Abstract
The paper considers the changes of immunological parameters of oral fluid for inclusion in a dental splinting of complex treatment ofpatients with chronic periodontitis of moderate severity. He was treated with 80 patients aged 25-50 30 patients additionally completed splinting of teeth (GLAS-SPAN). The results suggest that the inclusion of splinting of teeth in the standard treatment of patients with chronic periodontitis leads to normalization of the status of local immunity up to 12 months after graduation.
