From: Efficiency of biofilm removal by combination of water jet and cold plasma: an in-vitro study
Mean values and standard deviation of water contact angles (°) of specimen treated by water jet (WJ), curette + cotton swab (CC), cold atmospheric pressure plasma (CAP), combined treatment of WJ + CAP and CC + CAP, and the untreated positive control (PC) (n = 3, time span between treatment and measurement was 2 h). Additionally, mean water contact angle data for specimen immediately measured after CAP (CAP*, time span 10 min) are shown
