NC negative control, WJ water jet, WJ + CAP water jet and cold atmospheric plasma, CC curette + cotton swab, CC curette + cotton swab and cold atmospheric plasma
Comparisons were done using Mann–Whitney U tests. Benjamini–Hochberg corrected p-values (WJ vs. CC + CAP and CC vs. WJ + CAP were not compared); *significantly different compared to NC; †significantly different compared to WJ; ‡significantly different compared to WJ + CAP; Δsignificantly different compared to CC + CAP
