Aerosols and droplets in dental clinic:
- Most dental treatments require the use of instruments such as high and low speed handpieces, ultrasonic scalers, polishers and so on.
- During the implementation of these instruments, the combination of compressed air and water can vaporize virus and bacteria particles in the patients oral cavity.
Highspeed dental handpieces and ultrasonic instruments are particularly problematic because of their speed (400.000 rpm or 30 K etc.) and use of water for coolant and lavage. These atomized micro-droplets can drift a range of 1-2 meters around dental chair.These particles can also be inhaled by the dental professional, staff and other patients.
