Area covered by bacterial biofilm (%) and biofilm mean signal intensity in vitro, as evaluated by CLSM. Staphylococcus aureus (a,b), Pseudomonas aeruginosa (c,d) and Enterobacter aerogenes (e,f) biofilms were grown on ZnCl2-coated splints and on non-ZnCl2-coated splints without ZnCl2 as positive growth controls. Pieces of these splints were stained with propidium iodide (PI) and evaluated by CLSM for the area of each piece covered by bacterial biofilm (right column) and for the mean signal intensity, quantifying the amount of biofilm formed on the splint surface (left column). P-values are provided by unpaired t-test (*p 0.05; **p < 0.01; ***p < 0.001).
