Which statement describes aerosol-generating procedures?

• A. They produce airborne particles that may carry contaminants
• B. They produce no aerosols
• C. They are forbidden in dentistry
• D. They do not require PPE

Answer: (A)

Aerosol-generating procedures create fine droplets that can stay suspended in the air. In dentistry, tools like high-speed handpieces, ultrasonic scalers, and air-water syringes produce aerosols that mix with saliva and blood, forming airborne particles that may carry contaminants from the patient. Because these particles can travel and linger, they increase the risk of airborne transmission, which is why proper PPE and controls are essential. The other statements miss this risk: aerosol-generating procedures do produce aerosols, they are not forbidden in dentistry, and they do require PPE to protect against exposure.
