Green fluorescence (fluoresceindiacetate (FDA); alive): red fluorescence (ethidiumbromide (EB); damaged membrane dead) ratio of saliva biofilms after treatment with different procedures. Data are presented as mean ± SD (n = 8). *P < 0.05 versus NaCl control (within equally colored columns); **P < 0.05 versus Agent only for each agent separately; ^# P < 0.05 Plasma plus Agent versus Agent plus plasma for each agent separately. P values were retrieved from Mann-Whitney-U tests and were Bonferroni corrected.
