Abstract:
Objective To explore the method of intervening measure applied at dynamic state during ultrasonic scaling treatments and may control the aerosols and spatters in dental department so that we may provide safe clinical environment for dental personnel and patients. Methods 40 patients received ultrasonic scaling treatments were divided into experiment and control group. The experimental group received measures by the ozone air disinfector at the beginning of ultrasonic scaling treatments (the ozone air disinfector worked 5 minutes) and the control group was not received the device treatment.. Air samples were collected at different appointed period. Results A Mann-Whitney test was conducted to determine significant difference between the ultrasonic scaling treatments with the ozone air disinfector and the ultrasonic scaling treatments without the device at different appointed time. The general bacterial population in the air were lower in experimental group than in control group (P < 0.01). Conclusions The ozone air disinfector applied at dynamic state during ultrasonic scaling treatments may control the quantities of colony-forming units of aerosols and spatters in dental clinic. After dynamic disinfection, the quantities of colony-forming units may conform to the National Disinfection Technology Criteria.
