Objective: The purpose is to characterize the surface properties of specimens coated with titanium nitride (TiN) and to investigate the in vitro biofilm formation on TiN coated specimens.
Methods: Ti6Al4V specimens were coated with a <1 μm thick coating of TiN. Surface roughness, surface chemistry, and wettability were measured using 2D stylus profilometry, SEM/EDX, XPS, XRD, and contact angle analysis, respectively. The specimens were preconditioned with artificial saliva and thereafter incubated with a coculture of Streptococcus sanguinis, Actinomyces oris, and Porphyromonas gingivalis. Biofilm formation was evaluated with plate counts, qPCR, Live/dead, and Crystal Violet stai... view more»
