In vitro behavior of bacteria on fluoride Ion-corted titanium: With special regands on Porphyromonas gingivalis

This study focused on the antibacterial activity of the fluoride ions corted titanium. The profile of the elements of the modified material were analyzed with a X-ray photoelectron spectroscopy analysis system. At the same time, in vitro bacteria culture model was established to evaluate the influence of the modified titanium on the colonization and adhesion of Porphyromonas gingivalis (P.g.). It was confirmed by bacterial colony counting assays and SEM observations that fluoride ion-corted titanium could effectively influence the adhesion and growth of P. g. The current results indicated that fluoride ion corting could improve the antibacterial activity of titanium.
