Features of Candida biofilm formation on the surface of the polyurethane alloy used in bracket systems

Abstract

Currently, construction materials of various kinds are widely implemented in orthodontic practice. However, their chemical composition and surface microrelief determine the potential of the material for adhesion of conditionally pathogenic microorganisms inhabiting the oral cavity. A special danger in the development and progression of pathology of the dental system is represented by fungi of the genus Candida, which have an extensive set of pathogenicity factors. The aim of the study is to research and compare the ability of Candida albicans to formbiofilms on polyurethane braces. C. albicans strains were used from the collection of ATSS. It was found that the growth rate and functional activity of C. albicans strains allow them to form a large volume of biofilm on the polyurethane of braces, which may be associated with the creation of additional retention points by destroying the surface structure of the material.
