  • This study compared the IsoliteTM and saliva ejector on aerosol reduction during ultrasonic scaling. Fifty participants were randomly assigned to control (n=25, saliva ejector) or test groups (n=25, IsoliteTM). Plaque extent scores were recorded and aerosols were collected both during (timed period) and post (35 minute period) ultrasonic scaling in buffer in Petri dishes placed six inches from the participant’s mouth. Participants were surveyed regarding device acceptance. The during and post suspensions were plated to blood agar plates and recoverable colonies (CFU) were counted following anaerobic incubation. Significant contamination occurred during ultrasonic scaling in both device groups, as indicated by high CFU and the identification of strict oral anaerobes on all plates. A Student t-test revealed that the test device did not reduce aerosol contamination compared to the control device (p=0.25). Additional caution should be exercised with these devices to reduce the risk of exposure to potential pathogens.
