Effect of the use of different mouthwashes before ultrasonic cleaning on air quality in dental clinics
Objective To explore the effect of different mouthwashes on the bacterial count in the air of oral clinics during ultrasonic cleaning and the acceptance of mouthwashes by patients.Methods A total of 56 patients treated with ultrasonic cleaning were randomly divided into 4 groups according to the order of entry into the study,namely hydrogen peroxide group,chlorhexidine group,hypochloric acid water group,and control group,with 14 cases in each group.Patients were required to rinse with 40 mL of 1.50％hydrogen peroxide,0.12％chlorhexidine,100 mg/L hypochloric acid water,and sterile water for at least 1 min before ultrasonic cleaning.Before treatment,during treatment,and at 0 and 10 min after treatment,air samples were collected by natural sedimentation on a blood agar plate for 5 min,bacteria were cultured and the total number of colonies was counted,and bacterial species identification was performed.The patient's acceptance of the four mouthwashes was investigated through a questionnaire survey.Results After treatment with hydrogen peroxide,chlorhexidine,and hypochloric acid water,the total number of bacterial colonies in the air reached its maximum at 0 min.After 10 min of treatment,the total number of bacterial colonies in the air of all three groups decreased to 4 cfu/dish,with Staphylococcus pidermidis being the highest proportion.The hypochloric acid water received the highest acceptance.Conclusion Rinsing with 100 mg/L hypochloric acid water for 1 minute before ultrasonic cleaning can reduce the total number of bacterial colonies in the air of oral clinics,and has a higher acceptance.
