Abstract Background Using a rotary instrument or ultrasonic for tooth preparation is basic operation in the dental clinic that can produce significant number of droplets and aerosols. The droplet aerosol lead to transfer harmful germs. goal this study was analyze properties microbiological created by generated three common tooth-preparation instruments. Methods Streptococcus mutans UA159 used as biological tracer visualize passive sampling method map three-dimensional spatial distribution...
