The microbiome of oral cavity in healthy people and patients with periodontitis was analyzed to determine their adhesive properties and the ability to form biofilms. The study involved 2 groups: healthy, 18 people, and an experimental group, 20 patients with chronic generalized periodontitis moderate severity of the disease. The average age of the studied people was 35-45 years. Material - dental plaque, scraping from the mucous membrane of the back of the tongue, the contents of the periodontal groove and periodontal pocket, as well as oral fluid. The main method of diagnostic was bacteriological. The average adhesion index (AAI) was used to determine adhesion level of microorganisms to epithelial cells of oral cavity’s mucous membrane. The microbiota’s ability to form biofilm was tested on glass and plastic surface. The microbiota of oral cavity of patients with periodontitis was characterized by decrease in the frequency of bacteria of the genera: Streptococcus, Peptostreptococcus, Peptococcus, and an increase in Staphylococcus aureus, Veillonella spp., Bacillus spp. The microbiota of the oral cavity of patients with generalized periodontitis has a greater ability to adhere to the cells of the mucous membrane than in healthy people, while their ability to form biofilms and exhibit pathogenic properties is enhanced. The biofilm formation of microorganisms in healthy and sick people differs both on glass and on plastic surfaces.

Modern data of the etiology of squamous cell carcinoma (SCC) of the mucous membrane of the oral cavity (MMOC) show an increasing prevalence of the disease, a high mortality rate despite the development of modern methods of diagnosis and treatment. SCC is a group of polyetiological diseases. Among the most often etiological factors the use of tobacco products is found as one of the main cause of the disease with the division into active or passive methods of their use, prevalence and potential pathogenicity. Also the risk of the development of SCC MMOC depends on the consumption of alcoholic product as the long-acting traumatic factor. There were analyzed and considered the most common precancerous diseases of the mucous membrane of the mouth, their private and common significance in the structure of precancerous diseases. There was revealed the high correlation between periodontal disease and the development of SCC MMOC, which corresponded to the general assumption about the risk of oncology development against the background of chronic infection in the oral cavity. There were identified new data of the relation between the carriers of some types of the viruses of human papillomavirus and the development of SCC MMOC. Particular understanding of the causal relation of presented on-copathology allowed judging the lack of preventive measures, the necessity of required qualification of specialists of dental and related profile.

AbstractAccording to some studies, the Entamoeba gingivalis colonizing the gingival tissue is an important agent in bringing about periodontitis. Other studies, however, deem it an opportunist that is able to survive in the medium induced by periodontal disease. The aim of this study was to investigate the prevalence of Entamoeba gingivalis infection in patients from the Department of Periodontology, and compare this population with that of healthy people, so as to analyze the relationships between infection and patient sex and age. The result of this work is that in both groups, a correlation (p = 0,19) has been noted between the occurrence of amoebae and other diseases in the oral cavity. Indeed, 81,4% of all patients with some periodontal disease showed the presence of amoeba. Among those who are not afflicted with oral diseases, the presence of amoeba was indicated in 62,5% of the total. In addition, a correlation between the person's age and the presence of protozoa (p = 0,15) was strongly marked among women (p = 0,19). In the three age groups of women in this study (40-49, 60-69, and above 80 years), we observed a 100% presence of protozoa.Our study leads us to the conclusion that infections with Entamoeba gingivalis should be regarded as an factor that is associated with the pathological changes occurring in patients with periodontal diseases.

In Martinique, Bothrops lanceolatus snakebite, although relatively uncommon (~30 cases/year), may result in serious complications such as systemic thrombosis and local infections. Infections have been hypothesized to be related to bacteria present in the snake’s oral cavity. In this investigation, we isolated, identified, and studied the susceptibility to beta-lactams of bacteria sampled from the oral cavity of twenty-six B. lanceolatus specimens collected from various areas in Martinique. Microbiota from B. lanceolatus oral cavity was polymicrobial. Isolated bacteria belonged to fifteen different taxa; the most frequent being Aeromonas hydrophyla (present in 50% of the samples), Morganella morganii, Klebsiella pneumoniae, Bacillus spp., and Enterococcus spp. Analysis of antibiotic susceptibility revealed that 66.7% of the isolated bacteria were resistant to amoxicillin/clavulanate. In contrast, the majority of isolated bacteria were susceptible to the third-generation cephalosporins (i.e., 73.3% with cefotaxime and 80.0% with ceftazidime). Microbiota from B. lanceolatus oral cavity is polymicrobial with bacteria mostly susceptible to third-generation cephalosporins but rarely to amoxicillin/clavulanate. In conclusion, our findings clearly support that first-line antibiotic therapy in the B. lanceolatus-bitten patients, when there is evidence of infection, should include a third-generation cephalosporin rather than amoxicillin/clavulanate.

The article presents information on the liability of the dentist for reducing the risk of development of pathological processes, including malignant neoplasms of the oral cavity. A thorough inspection of the oral mucous membrane, in accordance with WHO recommendations provides a systematic survey of all departments of the oral cavity and surrounding tissues. This tactic can significantly reduce the risk of development of pathological lesions of the oral cavity, to prevent malignant transformation or provide early diagnosis.

Periodontal disease is known to be the most common and serious health problem in dogs today. Despite the rather large arsenal of medicinal substances, the problem of treatment and prevention of periodontal disease remains relevant. Based on this, the purpose of the work was to study the features of chronic catarrhal gingivitis and to develop an effective treatment regimen for dentistically ill dogs. For research, two groups of animals with chronic catarrhal gingivitis were formed in 5 dogs in each (control and experimental), selected on the principle of analogues in terms of age, character and localization of the inflammatory process. Animals of the control and experimental groups were performed tartar removal, irrigation of the oral cavity with water and drying of the mucosa with a sterile gauze swab. Dogs of the control group on the mucous membrane was applied 1 ml of septogel 2 times a day, and the experimental – argumentistin 2 times a day. Before and after the procedures on the mucous membrane was applied a 3 % solution of hydrogen peroxide. It was determined the prevalence of dental disease in dogs, the influence of microflora on the condition of the oral cavity of dogs with chronic catarrhal gingivitis, the clinical condition and the main indices and samples were studied, reflecting the intensity of the inflammatory process in the gums of sick dogs and was developed a method of treatment. The results of researches have shown that the use of argumentistin in the complex treatment of dogs with chronic catarrhal gingivitis helps to reduce the recovery period by 5 days.

Variants of pathological changes related to the group of white lesions: multiform erythema, flat lichen, candidiasis glossitis at the stage of formation of white foci. In this paper we consider the differential diagnosis of multiform erythema, planar lichen, candidiasis glossitis in the presence of signs of white plaque. Clarification of the diagnosis is based on a thorough examination and additional (including laboratory) research methods. Analysis of the results of observation of clinical cases of oral mucosa diseases to differentiate existing foci for correct diagnosis and subsequent treatment.The analysis of clinical cases of diseases of the oral mucous membrane indicates the similarity of their elements of destruction and manifestations of other symptoms, which greatly complicates the diagnostic search. A thorough survey, inspection, consultations of general specialists and additional laboratory tests allow to successfully solve the tasks
