Biofilm formation plays a major role in the pathogenesis of many oral diseases especially in peri-implantits. To evaluate the anti-biofilm effect of different plasma devices and processes we used different dental biofilm models: Candida albicans, Streptococcus mutans, Streptococcus sanguinis, aerobe multispecies human saliva and anaerobe plaque biofilms. After 10 min treatment we reduced the biofilms by 5 log10 steps using dielectric barrier discharge (DBD) plasma. Chlorhexidine is the gold standard antiseptic which achieved in the same time only a 1.5 log10 reduction. All plasma devices (DBD or plasma jets) damaged the membrane of the microorganisms but only etching plasma sources can remove the biofilm as shown in CLSM micrographs. It is possible to improve the plasma process using antiseptics like octenidine. This combination significantly reduced CFU values after 1 min plasma treatment compared to the plasma control. Beside the anti-biofilm effect an additional effect of plasma is the contact angle reduction of different titanium implant surfaces from 90° to super-hydrophilic (<5°). This can improve the implant healing process. Thus in the future, plasma could be an interesting treatment option in dentistry, especially in treatment of peri-implantits.
