Protective device to reduce aerosol dispersion in dental clinics during the COVID-19 pandemic.

ABSTRACT:

Aim

To describe the use of a new protective device to reduce aerosol dispersion in dental clinics during the COVID-19 pandemic.

Methodology

The device consists of a rigid translucent acrylic structure (methyl polymethacrylate), adjusted to the dental chair, involving the patient's head, neck and chest. There is also a piping system to generate negative pressure, for aspiration and filtering of the air inside the device chamber. The operator works through small holes in the acrylic structure, to reduce contact with the microparticles arising from aerosols during dental procedures. Simulated dental procedures using a fluorescent dye in the water of the dental equipment were carried out, with and without the use of the device. The presence of the dye was analysed at various loc
