What is the term for the minute particles that can remain suspended in the air and pose a risk in dental practices?

The term for minute particles that can remain suspended in the air and pose a risk in dental practices is aerosols. Aerosols are produced during various dental procedures, especially those that involve high-speed instruments, such as handpieces, ultrasonic scalers, and air-water syringes. These procedures can create a mist of tiny particles that can contain bacteria, viruses, and other pathogens, thereby increasing the risk of infection transmission among patients and healthcare workers.

In the context of infection control, understanding aerosols is crucial as they can linger in the dental operatory air for extended periods, potentially leading to respiratory exposures. Proper infection control measures, such as using high-efficiency particulate air (HEPA) filters, maintaining appropriate air circulation, and implementing personal protective equipment (PPE), help mitigate the risks associated with aerosol generation in dental settings.
