Objective The aim of this study was to design three apparatus for producing ozonated water in dental application, and investigate the safety, stability and bactericidal action of ozonated water in vitro. Method Three apparatus for producing ozonated water were manufactured for dental application. The concentration of dissolved ozone, pH, bromate and nitrite were measured respectively. Possible leakage of gaseous ozone of these devices was monitored. Finally, in vitro bactericidal action of ozonated water produced from these devices was investigated. Result Three apparatus for producing ozonated water were successfully manufactured for dental application, including ozone mouthwash maker, ozone toothbrush maker and ozone water jet oral irrigator. These devices were able to make stable ozonated water with a range of dissolved ozone concentration of 0.56-1.29mg/L, 0.38-0.50mg/L and 1.8-3.2mg/L respectively at 18-28℃. No leakage of gaseous ozone was detected. The levels of bromate and nitrite from ozonated water samples with various ranges of dissolved ozone concentration were 10-100 fold lower than Chinese national standard. All ozonated water samples made from tap water had neutral pH and contained no detectable bacteria. In vitro bactericidal studies indicated that the ozonated water made by these devices was an effective bactericidal agent for dental application. Conclusion These apparatus for producing ozonated water were able to safely make stable and effective bactericidal ozonated water for dental application.
