Enterococcus faecalis adherence and colonization on the root canal wall as observed by CLSM.
Notes: (A) Comparison of biovolumes calculated from the total fluorescence among groups (columns designated with different asterisk numbers are significantly different [P<0.05]); (B) background fluorescence produced by MCSNs; representative reconstructed CLSM images of the (C) blank control group; (D) Ca(OH)2 (calcium hydroxide) group; (E) MCSNs group; (F) Ag-MCSNs-A group; and (G) Ag-MCSNs-T group.
Abbreviations: Ag-MCSNs-A, nanosilver-incorporated MCSNs prepared by the adsorption method; Ag-MCSNs-T, nanosilver-incorporated MCSNs prepared by the template method; CLSM, confocal laser scanning microscopy; MCSNs, mesoporous calcium-silicate nanoparticles.
