Figure 2: Summary of all cell viability tests rinse products.The cell number/ visual field was counted using an automated digital process. The pretreatment values are shown in black with post-treatment in gray. A media change cause no significant decline in cell number, but treatment with CHX, carbamide peroxide (CP), essential oil-based rinse (EO) with and without alcohol, and an aloe vera-based product (AV) all caused a significant drop in cell numbers. Only the combination treatment did not statistically reduce the cell number. *indicates p < 0.05. CHX: chlorhexidine gluconate, CP: carbamide peroxide, EO: essential oils, and essential oils alcohol-free, comb: combination product, AV: aloe vera.
