| Abstract |
Aerosols generated in the mouths of dental patients were simulated in the laboratory by applying powered dental instruments to whole blood. Rates of production, particle size distribution, persistence, and blood content of the aerosols were measured. All the recovered particles could contain the 0.042µm hepatitis B virus and could be inhaled; many could be retained in the human respiratory system. Of the 0.06 to 2.5µm particles, 15-83% passed through the filter media of nine makes of protective surgical masks used by dentists. Findings lend support to the hypothesis of an airborne route for the hepatitis B infections reported for dental professionals. |
