Notes:
Vacuum plasma sprayed (VPS) hydroxyapatite (HA) coatings with silver-loadedzirconium phosphate antimicrobial have been prepared on titanium substrate. Antibacterial effectsof the coatings were studied by bacteria culturing using Porphyromonas gingivalis (Pg),Fusobacterium nucleatum (Fn) and Actinobacillus actinomycetemcomitans (Aa) as microorganisms.Simulated body fluid (SBF) test was carried out to evaluate the bioactivity of the coatings as well.The results obtained showed that the coatings exhibited a marked antibacterial effect against Pg, Fnand Aa when the content of antimicrobial was equal to or more than 5%. The antibacterialcapability of the coatings decreased in the following order: Pg, Fn, Aa. Bone-like apatite layer wasformed on the silver-containing HA coatings after immersed in SBF, suggesting that theirbioactivities were not affected obviously by the addition of silver-zirconium phosphateantimicrobial. This study indicated that silver-containing VPS HA coating is a prospective candidateas dental material
