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 locations, such as on personal protective equipment (PPE), the dental chair and on the clinic floor.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In the simulated dental procedure without the device, the dye was obvious on surgical gloves, aprons (waist, chest, legs, fists) and face shields, as well as on the dental chair (backrest, light reflector) and clinic floor. In the simulated dental procedure using the device, the dye was observed only on surgical gloves, apron (fists), inside the pipe system and internal walls of the acrylic chamber. There was a certain limitation of movement and visualization by the dentist whilst using the device.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The present device is a low\u2010cost complementary resource for use in conjunction with standard PPE, to reduce the transmission of SARS\u2010CoV\u20102 in the dental setting. Further clinical trials should be carried out to test the efficacy of this device to reduce aerosol dispersion and the consequent vector of contamination, as well as the ergonomic impacts related to its use.<\/jats:p><\/jats:sec>","DOI":"10.1111\/iej.13373","type":"journal-article","created":{"date-parts":[[2020,7,31]],"date-time":"2020-07-31T19:19:46Z","timestamp":1596223186000},"page":"1588-1597","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":29,"title":["Protective device to reduce aerosol dispersion in dental clinics during the COVID\u201019 pandemic"],"prefix":"10.1111","volume":"53","author":[{"given":"R.","family":"Teichert\u2010Filho","sequence":"first","affiliation":[{"name":"Programa de P\u00f3s\u2010Gradua\u00e7\u00e3o em Odontologia Escola de Ci\u00eancias da Sa\u00fade e da Vida Pontif\u00edcia Universidade Cat\u00f3lica do Rio Grande do Sul Porto Alegre Brazil"},{"name":"Centro M\u00e9dico\u2010Odontol\u00f3gico da Brigada Militar do Rio Grande do Sul Porto Alegre Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C.
