摘要：

This study aimed to compare the antibacterial effect of ozonated water and ozonated gas at different concentrations and exposure times.Staphylococcus aureusandEnterococcus faecaliswere exposed to ozonated water or ozonated gas at concentrations of 20, 40 and 60 mu g/mL for 1 and 2 minutes. A positive control with bacteria and a chlorhexidine 2% negative control were used. The number of colony-forming units (CFU/mL) was evaluated. The concentrations of 40 and 60 mu g/mL were significantly more effective. For theE. faecalis, ozonated gas was significantly more effective than ozonated water. When compared to controls, all ozone concentrations were effective in reducing bacteria.
