[Evaluation of the dynamics of prosthetic dental care provided to patients with the complete absence of teeth in the Perm district].

Background: Currently, one third of the world's population aged 65-74 years has partially or completely missing teeth. In our country, the data of epidemiological studies are scattered.

Objective: The aim of the study is assessment of the dynamics of the volume of orthopedic care provided to patients with complete absence of teeth in the Perm Region.

Express detection of Escherichia coli and bacteria of the Escherichia coli group at the oral cavity.

Currently, in the diagnosis of diseases, a decisive place is given to laboratory methods, which should be informative, relatively simple to perform and rapid. The article describes the approbation of a method for rapid detection of Escherichia coli and bacteria of Escherichia coli group in the oral cavity. Research involved 44 volunteers, who were sampled from the oral cavity, followed by incubation in Koda's medium.

[Colonization activity of conditionally pathogenic microorganisms and features of biofilm formation on the surface of thermoplastic polymer material].

The Purpose Of The Study: Was to assess the microbial colonization and biofilm-forming activity of conditionally pathogenic microorganisms in vitro to samples of acrylic-free thermoplastic polymer material and to assess the possibility of its use for the manufacture of removable tooth splinting structures by injection method.

Materials And Methods: The reference strains . Biofilm-forming activity was assessed by the level of ethanol extraction of a 0.

A new approach for the study of the morphological structure of microbal biofilms.

Microbial biofilms are heterogeneous, moving and constantly changing communities of microorganisms, often of various taxons. Approaches to study and assessment anti-biofilm drugs widely available today do not adequately assess their effects, while the results of studying the interaction of drugs with components of the film composition can provide them the right choice. The aim of investigation was to test a new method of morphological evaluation of biofilms.

[Morphology of root dentine in teeth extracted because of chronic apical periodontitis in various irrigation protocols].

The purpose of the study was to evaluate the degree of purification of the deltoid root canal branching during endodontic treatment of teeth. Morphological assessment of dentine of 14 extracted incisors and premolars in patients aged from 24 up to 56 years with the diagnosis chronic apical periodontitis was conducted in two experimental groups: main (1 group, 7 teeth) and control (2 group, 7 teeth). In the 2 group conventional root canal treatment was carried out with processing of 3% solution of sodium hypochlorite and final sealing with gutta-percha pins by lateral condensation.

[Etiology of purulent-inflammatory processes in the genital tract: suspicions of clinicians and problems of laboratory confirmation.].

Despite the long history of the study, laboratory diagnosis of gonococcal infection remains a complex task that does not have a clearly regulated effective solution. Aim of investigation was to assess the species diversity of the microbiota of the genital tract of men and women with suspected acute genital gonococcal infection (AGGI) using test systems of Russian manufacturers. A study of samples of the contents of the urethra of 69 men and posterior vaginal fornix fluids of 33 women of reproductive age with characteristic clinical manifestations and a presumptive diagnosis of AGGI was made.

[Determination of biofilm forming activity of microorganisms on synthetic polymeric materials.].

Microorganisms are able to form biofilms on surfaces of biotic and abiotic nature. In turn, in human biotopes there are optimal conditions for the implementation of biofilm-forming activity. Moreover, in medical practice, polymeric materials are often used for drainage or prosthetics, which can also be successfully colonized by bacteria.

[The determination of biofilm composition of gram-positive bacteria.].

Current methods of biofilm imaging do not support a differentiated assessment of its composition, since it is not possible to establish a substrate stained with crystal violet, as this dye can form complexes with both intracellular and extracellular structures. This approach does not adequately assess the anti-biofilm effects of drugs, while the results of studying the interaction of drugs with biofilm components can ensure their most correct choice. The aim of investigation was to study the possibility of applying the original modification of the current method to determine the ratio of the cellular part and the matrix of biofilms of gram-positive microorganisms.

[Characteristics of lactobacteria strains, having diagnostic significance in gynecological practice.].

Background: Nowadays, in the presence of wide diagnostic possibilities, laboratory diagnostics of microecological disorders of vaginal biotope are often limited to clinical data, microscopic examination results and the use of a culture method. However, with such a complex it is impossible to get an answer about the functional activity of microorganisms. The aim of investigation was to evaluate the information content of a combined study of growth parameters and the ability to produce lactic acid by clinical strains of Lactobacillus spp.

[GUT AND VAGINAL MICROBIOTA IN FEMALE WITH REPRODUCTIVE DISORDERS ASSOCIATED WITH GASTROINTESTINAL DISTURBANCE].

The aim of research - a comparative study of the microflora of the vagina and bowel in women with secondary infertility and gastrointestinal distress. Materials and methods. We examined gut and vaginal microbiota in 17 infertile women according to the presence or absence of gastrointestinal diseases.
