Cytotoxicity and Antimicrobial Activity of Oral Rinses In Vitro

Figure 2

Phase contrast microscopy of gingival fibroblasts exposed to different oral rinses. Cultured gingival fibroblasts were exposed to a tenfold dilution of a panel of oral rinses for 2 minutes. Afterwards, cell morphology was analyzed via phase contrast microscopy. A physiological bipolar cell shape was observed in #1 to #5, which turned into a round cell shape in #7 to #12. Cell detachment was observed after exposure to oral rinse #6. Images were taken at a tenfold magnification.
