Abstract：Objective To detect the effect of gargling with electrolyzed oxidizing water(EOW) on the number of air colonies before ultrasonic cleaning, and to provide data for clinical use of electrolyzed oxidizing water in order to prevent or reduce cross infections. Methods A total of 90 patients admitted to the Department of Stomatology of our hospital between March 2018 and December 2018 were selected and randomly divided into three groups, with 30 cases in each. Before ultrasonic cleaning, the three groups of patients were gargled with sterile distilled water, 0.12% compound chlorhexidine solution and electrolyzed oxidizing water for one minute respectively. Before, during, immediately after and 10 minutes after ultrasonic cleaning, samples were taken at the radius of 30cm and 1m centered on the patient's mouth for bacterial culture, and the number of colonies in the air was compared. Results There was no statistically significant difference between the three groups in basic information about these patients,such as gender, age, daily brushing times and duration of brushing each time, or in the simplified oral hygiene index before cleaning (P>0.05). There was no statistically significant difference in the number of colonies in the air at the radius of 30 cm and 1 m away from the patient' oral cavity before ultrasonic cleaning (P>0.05). During cleaning, immediately after cleaning, and 10 minutes after cleaning, the number of colonies in the air 30 cm away from the patient's mouth was smaller in the oxidation potential water group than in the other two groups (P＜0.05), and the number of bacteria in the air 1m away from patient' oral cavity in the oxidized water group was smaller than in the other two groups (P<0.05). Conclusions Electrolyzed oxidizing water, when used as a gargle, can effectively reduce the number of bacterial colonies in the air and prevent or reduce the occurrence of cross-infections.
