ABSTRACT
Dental health care providers and patients are exposed duringongoing work to contamination by the water used in the dentalunits, due to accidental swallowing or aspiration of thesprays generated by the high-speed handpiece and the threewaysyringe. This study evaluated the quality of water indental units in the public dental care system of Maceió,Alagoas, Brazil, by conducting analyses of contamination bytotal coliforms, E.Coli, heterotrophic bacteria and filamentousfungi. We collected 200 mL of water at 5 sites in 6 dentaloffices of the Department of Health located in different partsof the city. A total 212 isolates and 16 genera of filamentousfungi were identified in the water collected from the dentalunits. Total coliforms indicated that the water used in dentalunits was not appropriate for human consumption. The highlevels of contamination found in this study showed that waterwas a potential source of cross-infection...
RESUMO
Durante a rotina de trabalho, a equipe odontológica e ospacientes ficam expostos a possível contaminação pela água utilizadanas unidades dentais, devido à ingestão acidental da águaou pela aspiração dos sprays gerados pela caneta de alta rotaçãoe seringa tríplice. Este estudo avaliou a qualidade da água usadaem consultórios odontológicos da rede pública estadual deMaceió, Alagoas, Brasil, através da análise de contaminação porcoliformes totais e E.coli, bactérias heterotróficas e fungos filamentosos.Foram coletados 200 mL de água, em cinco pontos deseis consultórios odontológicos pertencentes à Secretaria Estadualde Saúde, localizados em diferentes bairros da cidade. Umtotal de 212 isolados e 16 gêneros de fungos filamentosos foramidentificados. A presença de coliformes totais indicou que a águautilizada nas unidades dentais era imprópria para consumohumano. O alto índice de contaminação mostrou que as águasestudadas eram uma fonte potencial de infecções cruzadas...
