Synergistic anti-biofilm effect of AgNPs and ebselen on P. gingivalis. (A) SEM images and (B) CLSM images of the biofilm formation experiment; (C) Biofilm thickness quantified by CLSM; (D) SEM images and (E) CLSM images of the biofilm destruction experiment, the red arrow in SEM images indicated ruptured P. gingivalis; (F) EDS result of destructed biofilm. Scale bars in SEM images: 2 μm, scale bars in CLSM images: 100 μm. Data were presented as the mean ± SD. Compared with the control group, **P < 0.01, ***P < 0.001.
