The aim: To study possibilities of prognosis of pathological wear of tooth hard tissues development depending on the functional activity of masticatory muscles. Materials and methods: In order to achieve the goal of the study, a survey of patients at the age of 19 to 69 years was conducted for precision of number of persons who have increased tooth wear. During the examination of all patients, three groups were selected: control and two researched ones. Patients in the control group (30 patients between the age of 18 and 60 years old) had an intact dentition without any visible sign of increased tooth wear. The researched groups included 25 patients aged from 18 to 60 years old. The second research group included patients who had increased tooth wear of I-III level. The children of the patients of the II group with or without any sign of increased tooth wear were referred to the third research group. Results: The method of electromyography was performed for the study of peculiarities of the muscular activity of the maxillofacial area of the patients of the control and research groups. In our opinion, all manifestations of increased tooth wear are related to changes in the muscle system, the motor apparatus and the nervous activity of an organism. Conclusions: The study of direct muscular apparatus and related bone system may predict the possibility of developing of an increased tooth wear of young patients in the future and prevent its development, as well as to justify the application of a prevention and treatment plan of the studied pathology.
This article presents the results of a study into the influence of the diet, air temperature and relative air humidity, and soil temperature on the average weight of Helix pomatia in captivity. It was shown that vegetables included in the mixed leaf-vegetable diet mitigated the effect of a high air temperature and a low relative humidity. It was established that the air temperature and relative humidity had opposite effects on weight gain in Helix pomatia. The increase in temperature predetermined the weight loss. Despite the high temperature, a humidity of over 75% caused all the molluscs gain weight regardless of their diet.
The aim: The purpose of the study is to characterize the influence of quantitative and qualitative composition of gingival microbiota on the status of the main immune system cells, localized in the gums, in chronic generalized catarrhal gingivitis in children. Materials and methods: The study involved 26 children aged 9 to 16 years, patients with chronic generalized catarrhal gingivitis mild to moderate severity (CGCG) and 18 children with intact gums were comparison group. We determined the hygienic indices Fedorov, has been received, Silness-Loe, PMA, bleeding index for Myuleman and intensity of caries index CFD + cf, CFD. Histological and immunohistochemical studies were performed on serial sections kriostatnyh who made biopsy of gingival papillae. Microbiological study gingival part of crown plaque was performed by multiplexed PCR in real time. Results: Value hygienic indices in children with CGCG higher than in healthy, indicating the difficulty of care in the presence of periodontal inflammation. As a result of immunohistochemical studies revealed that HLA-DR + cells under conditions of active disease migrate to mucosal lamina propria epithelium. Number of CD3 + cells in the epithelium CGCG was significantly higher than the number in the intact epithelium and was the most numerous of population. In the biopsy of affected children significantly reduced the number of CD4 + cells. When CGCG quantitative total bacterial mass, Lactobacillus spp., Enterobacteriaceae, Gardnerella vaginalis / Prevotella bivia / Porphyromonas spp. in the sample CROWN dental plaque was significantly higher than rates under physiological conditions, and may serve as diagnostic criteria of dysbiosis. Conclusions: So, CGCG is a disease in the etiology of which is one of the leading roles played by microbial factor, namely, the value of the quantitative ratios of certain types of microorganisms of dental plaque compared to the total bacterial mass of plaque. Therefore, it is reasonable to include comprehensive treatment CGCG drugs in children, leading to natural immunostimulation which causes restoration of local immunity in the gum tissue and drugs to restore quantitative and qualitative composition of normal microflora of the child, thus providing a high therapeutic effect and serve as justification their choice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
