Resumo
A pandemia provocada pelo novo coronavírus, responsável pela COVID-19, alertou a comunidade odontológica, quanto ao risco de contaminação cruzada do cirurgião dentista, sua equipe e pacientes, principalmente devido à grande quantidade de bioaerossóis gerado pelos equipamentos odontológicos de uso rotineiro. Esse estudo teve como objetivo comparar a dispersão do aerossol gerado por diferentes equipamentos odontológicos, bem como verificar a eficácia do uso de um dispositivo desenvolvido para o controle da dissipação do aerossol gerado pelo aparelho piezo-eletro. Como objetivo secundário, verificou-se a efetividade da refrigeração dos equipamentos utilizados. Para a verificação da dissipação de aerossóis, foi utilizado um manequim de estudo em Odontologia, acoplado a uma cadeira odontológica em um consultório de 2,40 x 2,60 de tamanho. Foram testados 2 aparelhos divididos em três grupos: GRUPO AR - alta rotação, GRUPO PE - piezo-eletro e GRUPO PESC - piezo-eletro com Spray control®. Os resultados mostraram uma menor dispersão no grupo PESC, seguido pelo grupo AR. Em relação à temperatura, observou-se que todos os grupos controlaram de forma eficaz o aumento de temperatura, sendo a AR a mais eficiente, seguida pelos dois grupos do Piezo, levando a conclusão que o Spray Control além de não gerar dispersão de aerossol, mantém a refrigeração adequada ao dente durante seu uso.
The pandemic caused by the new coronavirus, responsible for COVID-19, alerted the dental community to the risk of cross-contamination of the dental surgeon, his team and patients, mainly due to the large amount of bioaerosols generated by routine dental equipment. This study aimed to compare the dispersion of aerosol generated by different dental equipment, as well as to verify the effectiveness of using a device developed to control that dispersion generated by the piezo-electro device (CVDENTUS LTDA). As a secondary objective, was verify the effectiveness of refrigeration of the equipment used. For that dissipation of aerosols, a dental study mannequin was used, attached to a dental chair in a 2.40 x 2.60 office. Two devices were tested, divided into three groups: GROUP AR - high speed, GROUP PE - piezo-electro and GROUP PESC - piezo-electro with Spray control®. So The results have shown a lower dispersion in the PESC group, followed by the AR group. Regarding temperature, it was observed that all groups effectively controlled the temperature increase, with AR being the most efficient, followed by the two groups of Piezo, leading to the conclusion that the Spray Control device, in addition to not generating aerosol dispersion, maintains adequate cooling to the tooth during procedures
