Low-Temperature Plasma Short Exposure to Decontaminate Peri-Implantitis-Related Multispecies Biofilms on Titanium Surfaces In Vitro

Figure 2

Four-species biofilm growth on blood agar plates. A. naeslundii shows crème/red-pigmented round colonies without hemolytic halo, P. gingivalis presents black-pigmented round colonies with a hemolysis halo, S. oralis grows characteristically in chains and forms small white colonies, and V. dispar colonies show a transparent halo with a white spot in the middle.
