Evaluation of susceptibility of metalloacrylic dentures to the colonization by opportunistic pathogenic microflora in vitro

The objective of this study was the comparative evaluation of the survival rate of test cultures of opportunistic pathogenic microorganisms (S.aureus, ….coli, St.pyogenes, P.aeruginosa, '.albicans) allowed to colonize in vitro metalloacryl materials that are used for the coating of tooth prostheses including hybrid and micro-filled composites "Symfony" (3M-ESPE), "Artglass" ("Heraeus Kulzer"), and polymeric materials based of monofunctional methacrylates "Vitapan Monopast" ("Vita"), "Sinma-M" ("Stoma"). It was demonstrated that the polished photopolymeraizable hybrid composite material "Symfony" (3M-ESPE) exhibits strong hydrophobic properties, a highly uniform surface and almost complete lack of porosity. Taken together, these characteristics account for the highest resistance of "Symfony" (3M-ESPE) to the colonization by opportunistic pathogenic microflora compared with other metalloacrylic plastic materials.
