Teste ergonômico de protótipo de uma camâra de contenção de aerossol utilizada em odontologia

Abstract

The purpose of this study was to evaluate under the perception of dentistry students the work ergonomics using an aerosol containment chamber prototype and to determine possible necessary changes for its use. An aerosol containment chamber prototype was built of PVC pipes and transparent acrylic sheets. The aerosol containment chamber prototype was tested for its ergonomics in clinical practice, the dental care was simulated on a dental mannequin. In the simulation, 20 participants, who are students from the eighth to the tenth semester of the Dentistry Course at the Faculty of Dentistry of Universidade Federal de Juiz de Fora, carried out the construction of a Class I cavity in a lower molar and an upper molar and soon after answered a questionnaire that addressed information about the work ergonomics related to accomplish the service using the prototype. The research was done at the clinic of the Faculty of Dentistry of the Federal University of Juiz de Fora. The results of this research were that the use of the dental chamber prototype encountered difficulties when preparing upper teeth and when changing instruments during the procedure. It proved to be efficient when working on teeth in the lower dental arch and on the position of the spine. It can be concluded that the prototype presented limitations when working on the upper dental arch and regarding the exchange of instruments, but it presented good ergonomics when working on lower teeth and a good position of the spine. Therefore, changes are needed for its use in the dental clinic.
