OBJECTIVES: To reduce the spread of the infection, especially during aerosol generating procedures, we invented``The Cupola", a shield that creates a mechanical barrier around the patient's head and body . With this pilot study we aimed to assess the effectiveness of an additional layer of protection (The Cupola) developed for providers working in the oropharyngeal region .
RESULTS: The mean number of 0.3 μm particles with no Cupola was 3777 (SD: ± 556), with The Cupola was 2068 (SD: ± 1468) and with the Cupola and Drape was 2031 (SD: ± 1108) (p <0.015). The mean number of 0.5 μm airborne particles with no Cupola was 65 (SD: ± 7), with The Cupola was 29 (SD: ± 28) and with the Cupola and Drape was 28 (SD: ± 23) (p <0.05). Results showed a significant reduction of aerosols generated during simulated dental procedures when the Cupola was used . The Cupola offers an extra layer of protection in addition to the recommended personal protective equipment.
