“…It is known that reactive species are formed as well as hydroxyl groups are attached (Kolb et al. ) on the Ti surface when oxygen is admixed into the plasma and thus hydrophilic characteristics result. Hydrophilic surfaces improve cell adhesion on implant materials (Horbett et al.…”

“…Previous studies have found that plasma treatment formed various oxygen functional groups on the surface of materials through chemical oxidation, which breaks C-C and C-H bonds on the surface and removes carbohydrates connected to C-H bonds [ 38 , 39 ]. It was also reported that oxygen, mixed for plasma treatments, attaches a hydroxy group (O-H) on the surface of titanium, and generates reactive oxygen species (ROS), which improves hydrophilicity [ 40 ].…”

Peri-implantitis is an inflammatory disease similar to periodontitis, caused by biofilms formed on the surface of dental implants. This inflammation can spread to bone tissues and result in bone loss. Therefore, it is essential to inhibit the formation of biofilms on the surface of dental implants. Thus, this study examined the inhibition of biofilm formation by treating TiO2 nanotubes with heat and plasma. Commercially pure titanium specimens were anodized to form TiO2 nanotubes. Heat treatment was performed at 400 and 600 °C, and atmospheric pressure plasma was applied using a plasma generator (PGS-200, Expantech, Suwon, Republic of Korea). Contact angles, surface roughness, surface structure, crystal structure, and chemical compositions were measured to analyze the surface properties of the specimens. The inhibition of biofilm formation was assessed using two methods. The results of this study showed that the heat treatment of TiO2 nanotubes at 400 °C inhibited the adhesion of Streptococcus mutans (S. mutans), associated with initial biofilm formation, and that heat treatment of TiO2 nanotubes at 600 °C inhibited the adhesion of Porphyromonas gingivalis (P. gingivalis), which causes peri-implantitis. Applying plasma to the TiO2 nanotubes heat-treated at 600 °C inhibited the adhesion of S. mutans and P. gingivalis.

“…The group of Kolb reported that dc-voltagedriven micro-hollow cathode operated in pure air at at- mospheric pressure generating 20 mm afterglow jet able to inactivate Candida yeast in a single treatment of 90 s and 1 cm 2 of treatment area. Animal studies showed no skin damage even with exposures 10 times longer than needed for pathogen extermination [90,91].…”

Advanced oxidation processes, especially induced by non-thermal plasmas, are widely known for their high sanitation efficiency. The paper presents general overview of atmospheric pressure plasma jet (APPJ) reactors for bactericidal decontamination purposes. In the conclusion part, the basic requirements for APPJ as a tool for biomedical applications including the treatment of living tissues are highlighted.
