Which disease is listed as a dental aerosol that may cause disease?

• A. Tuberculosis
• B. E. coli
• C. Saliva
• D. Water

Answer: (A)

Aerosols produced during dental procedures can carry infectious agents from the patient’s mouth. Tuberculosis is an airborne infection spread by inhaling aerosolized droplets that contain Mycobacterium tuberculosis, so it’s the disease that could be transmitted via dental aerosols. The other options don’t fit because E. coli is not typically spread through inhaled dental aerosols, saliva is a fluid that can carry pathogens but isn’t itself a disease, and water is not a disease.
