Escudo de Controle de Aerossóis – ECA: criação de um dispositivo para auxiliar nos atendimentos odontológicos

Abstract

Aerosols are small particles generated by devices using compressed air and water pressure. When performing dental procedures, aerosols are dispersed and can contaminate the environment and people by microorganisms contained in saliva and blood. In view of the current pandemic scenario of the new COVID-19 (2019-nCOV) considered a global public health risk according to the WHO and due to the proximity of dental professionals to patients, the objective of this paper is to describe the creation and development of a patent for a device called the Aerosol Control Shield – ECA. It refers to a research with a descriptive qualitative approach, in which bibliographic research was carried out using the Pubmed database, in the years 2020 and 2021 and MESH descriptors: “covid“ AND “dentistry“, “aerosol reduction device“ AND “dentistry“, “biosafe“ AND “aerosol“, for knowledge of the current scenario and search for alternative devices to control aerosols in dental clinics. This research was the basis for the creation of the ECA device, created at the UNDB University Center, by the institution's dentistry and engineering team, which is composed of a circular acrylic rim wrapped with a fenestrated non-woven fabric (TNT) field structured by two flexible rods and two immobile rods for attaching to the dental chair. The COVID-19 post-pandemic scenario showed great potential for virulence and cross-contamination indoors. Thus, it is concluded that biosafety measures, through the physical barrier, such as the ECA, must be used in order to minimize the spread of aerosols.
