Abstract

Adhesion, growth and formation of biofilms of microorganisms are possible on the surface of polymers used for prosthetics. The development and spread of microorganisms cause an infectious process. The processes of biofilm formation on acrylic plates used in orthodontic practice were studied. The possibilities and features of biofilm formation by strains of conditionally pathogenic microorganisms of the genera Enterobacteriaceae, Staphylococcus and Candida are shown. It has been established that colonization by microbial flora is determined by the characteristics of the pathogen and the type of basis of the dental apparatus. Using the example of Escherichia coli, Staphylococcus aureus and Candida albicans strains, the features of biofilm formation on acrylic plastics of cold polymerization such as "Belacryl pink" and "Belacryl white" (Russia); "Redont pink" and "Redont white" (Ukraine), "Villacryl Ortho pink" and "Villacryl Ortho white" (Poland) are shown. The possibilities of pathogen adhesion on basic devices made of a new light-curing polymer "Nolatek pink" and "Nolatek white" (Russia) are considered. The mechanisms of the microbiocenosis biofilm formation and degradation in the oral mucous biotope are discussed.

Keywords: prosthetics; basis acrylic plastics; biofilm forming; conditionally pathogens; cold-curing polymers, light-curing polymer.
