Abstract: | In this study, the adhesion of radioactively labeled Actinomyces viscosus (A.viscous), Actinobacillus actinomicetemcomitans (Aa) and Porphyomonas gingivalis (P gingivalis) to titanium (Ti) and Ti6Al4V alloy (Ti‐alloy) coated with albumin or human saliva was investigated. All the tested bacteria displayed greater attachment to Ti‐alloy than to Ti. P. gingivalis exhibited less adhesion to Ti and Ti‐alloy than did the other bacterial strains. Adhesion of A. viscosus and Aa was greatly reduced when Ti or Ti‐alloy were coated with albumin or saliva. P. gingivalis demonstrated a lesser reduction in adhesion to albumin or saliva‐coated surfaces. The results show that oral bacteria have different adhesion ffinities for Ti and Ti‐alloy and that both albumin and human saliva reduce bacterial adhesion. |
