Figure 1: Effect of rinse agents on the viability of oral fibroblasts.Cells were plated into 96 well plates and images captured prior to treatment (upper panels). After treatment, images were captured for the same wells, and automated cell counts conducted. The images illustrate the typical results when cells were exposed to the rinse containing chlorhexidine gluconate, carbamide peroxide, essential oil product, and a combination product. Black arrows indicate examples of rounded cell structure. White arrows indicated elongated cells. Scale bar = 100 μm.
