[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.
