Which of the following is a common example of dental equipment that produces aerosols?

The ultrasonic bath is indeed a common example of dental equipment that produces aerosols. This device is used to clean dental instruments by generating high-frequency sound waves that create tiny bubbles in a cleaning solution. When these bubbles collapse, they generate a force strong enough to dislodge debris from the surfaces of the instruments, which can cause small droplets of liquid and aerosols to form. These aerosols may contain contaminants, including potential pathogens, making infection control crucial when using this equipment.

In contrast, a dental chair does not produce aerosols, as it simply provides a supportive seat for the patient without any fluid or air movement that would aerosolize particles. Cotton rolls are used to absorb saliva and moisture but do not create aerosols themselves. Similarly, a dental mirror is a reflective tool for viewing the oral cavity and does not generate aerosols during its use. Understanding the operation and implications of these various tools is vital for effective infection control practices in dental settings.
