Osteoblast growth, after cleaning of biofilm-covered titanium discs with air-polishing and cold plasma.

Aim: To investigate the effects of a combined biofilm removal with an optimized air polishing and a cold plasma device on cells in vitro.

Materials And Methods: A 7-day-old biofilm was removed from rough titanium discs with an air-polishing device with erythritol powder (AP) or with a cold atmospheric pressure argon plasma (CAP) device or in combination of both (AP + CAP). The removal efficacy was evaluated by subsequent cell seeding of osteoblast-like cells (MG-63).
