Comparative analysis of adhesion of microbial flora from the oral cavity to the base materials for polyurethane and acryl-based jaw prostheses

The present in vitro experimental study had the objective to compare the adhesive power of different microorganisms known to occur in the oral cavity with respect to base prosthetic materials. The oral microbial flora was presented by the following species: Streptococcus milleri, Streptococcus mutans, Enterococcus faecalis, Actinomyces naeslundii, Candida albicans, Veillonella parvula, Prevotella intermedia, Porphyromonas gingivalis, and Actinobacillus actinomycetemcomitans. We evaluated their adhesion to base cold- polymerized plastics Redont and Protakril (both the Ukraine), heat-polymerized plastics Ftoraks (the Ukraine) and StmAkril (Russia), and to polyurethane-based Dentalur (Russia). The removable laminar prostheses for patients presenting with either complete or partial edentia were manufactured by EHF-polymerization of a relevant base plastic material.
