Aim. To assess the effectiveness of nanosilver gel NSG in comparison to chlorhexidine gluconate CHX and camphorated phenol CP against Enterococcus faecalis E.f biofilm. Methods and Materials. Two tests were done, methyl thiazolyl tetrazolium MTT assay and confocal laser scanning microscopy CLSM analysis, to determine the effectiveness of NSG, CHX, and CP on E.f biofilm. Polystyrene microtiter 96- and 6-well plates were used for MTT and CLSM, respectively. Nanosilver gel was in three concentrations 0.05%, 0.1%, and 0.2%, chlorhexidine gluconate used was 2%, and camphorated phenol and normal saline were as control. Analysis was done using one-way ANOVA; the post hoc test was run for multiple comparisons. The level of statistical significance was set at . Results. One-way ANOVA showed significant differences among groups 0.05% NSG and CP, 0.1% NSG and CP, 0.2% NSG and CP, 0.1% NSG and 2% CHX, 0.2% and NSG and 2% CHX and also showed significant difference between groups -ratio 87.823. A post hoc Tukey’s test revealed no significant difference between chlorhexidine gluconate and 0.05% nanosilver gel . Conclusions. 0.1% and 0.2% nanosilver gel is more effective on Enterococcus faecalis biofilm as compared to chlorhexidine gluconate and camphorated phenol.
