The problem of complications arising after dental implantation is still relevant. The aim of the work was to investigate the effect of various types of removable appliances and dental implants on the oral microbiocenosis during orthopedic treatment of 64 people: 12 patients of the first index group, 40 patients of the second index group and 12 people of the control group. 6 months after the implants were installed, as a result of a microbiological study of the oral cavity, the differences were found in the qualitative composition of the microflora of the mucous membrane around the neck of the dental implant. In the first index group representatives of normal microflora prevailed. In 100% of cases Streptococcus vestibularis was isolated, from more than half patients S. oralis, S. mitis, Rothia mucilaginosa were isolated, S. gordonii was isolated from one patient. In the second index group, a significant diversity of microbial species was observed, including enterobacteria, which were isolated from 22.5% of the examined patients. In the control group, in addition to representatives of the normal microflora of the oral mucosa S. vestibularis (75.5%), S. oralis (50.0%), Neisseria subflava (66.7%) and Haemophylus parainfluenzae (50.0%) were found. From all patients of the control groups S. gordonii was isolated, as well as the other potentially pathogenic streptococci species, S. anginosus and S. constellatus by 66.7%. The type of removable appliances and dental implants used affects the microflora composition of the oral cavity, and, consequently, the further prognosis and the risk of complications. Collapsible dental implant supported removable prosthetic appliances with a metal frame and fixing elements, telescopic crowns and clasps less than other types of prosthetic appliances change the qualitative composition of the microflora of the oral mucosa around the neck of the dental implant.


Dear researcher!
At the end of 2015, Bulletin of RSMU saw an important change in its typographic design and content. We formulated new editorial policies and established strict ethical standards for submitted manuscripts in accordance with the guidelines of reputable international bodies. As a result, about a quarter of the submitted works have been rejected, the primary reason being the author trying to submit a previously published article. Sometimes authors believe that by making slight changes to the introduction, excluding a few people from the study, performing a new statistical analysis, and thus obtaining totally new results they will turn their old manuscript into a novel work. That is why we would like to talk about scientific integrity, honesty, plagiarism, and self-plagiarism in our special project “Author’s work”.
Richard FEYNMAN Cargo cult science
American physicist Richard P. Feynman, a Nobel laureate, was always very scrupulous about the quality of a research study. During his commencement address at the California Institute of Technology in 1974, he talked about scientific integrity and honesty and warned young researchers “not to fool” themselves. A must-read for anyone who believes he/she is a true scientist.
Ivan PAVLOV On the Russian mind
In 1918, Russian physiologist Ivan Pavlov, a Nobel laureate, delivered two lectures: on the mind in general and the Russian mind in particular; on those mind qualities that determine the success of a research work and on how these qualities are present in the Russian mind. Pavlov's thoughts are an effective vaccine against poor intellectual work.
