(A, B) Confocal microscopy images of plaque biofilm development on hydroxyapatite-coated disks over 3 days in the presence of (A) 5 μg/mL and (B) 10 μg/mL peptide or water as a control. The scale bar represents 200 μm. (C) The proportion of dead biofilm bacterial cell volume during 3-day biofilm development in the presence of peptides 1018 and DJK-5. (D) Total biovolume of plaque biofilm formed in 3 days in the presence of peptides. Error bars represent the standard deviations calculated from three independent experiments.
