EVALUATION OF THE GENUS CANDIDA FUNGI ADHESIVE PROPERTIES ON THE MATERIALS USED IN DENTISTRY
Abstract
Introduction. Acrylamide plastics are widely used in orthopedic dentistry. Studies of their susceptibility to microbial adhesion are relevant, since the restorative material made on the basis of these polymers can become a reservoir for microorganisms that can infect peri-implant tissues and cause inflammation. The purpose of the study was to test the adhesive ability of clinical strains of Candida to samples of acrylamide plastics. Materials and methods. 50 clinical strains of Candida fungi have been studied for the formation of biofilms during cultivation on acrylamide plastics. Plastic samples were treated with an inoculum of fungal cultures for 48 h at 37 °C. The values of their optical density (λ=560 nm) were a quantitative assessment of the biomass of the formed films. The results of the study. Quantitative analysis of the biofilm biomass showed that after 48 h all fungal strains formed a biofilm on the surface of the tested polymer discs. The highest quantitative values of the biofilm biomass were noted in the cultivation of C. albicans. Conclusion. It was noted that the type of material is not a key growth restriction factor for C. albicans. A set of measures is needed that combines optimal mechanical processing methods with the use of antimicrobial drugs to prevent the formation and accumulation of biofilms.
