O objetivo do presente estudo \u00e9 comparar a efic\u00e1cia dos m\u00e9todos de esteriliza\u00e7\u00e3o por autoclave e \u00f3xido de etileno (OE) de objetos produzidos pela impress\u00e3o 3D com material \u00e1cido polil\u00e1tico (PLA, na sigla em ingl\u00eas).<\/jats:p><jats:p>\n          M\u00e9todos\u2003Quarenta objetos em formato c\u00fabico foram impressos com material de PLA. Vinte eram s\u00f3lidos e 20 eram ocos (impressos com pouco enchimento interno). Vinte objetos (10 s\u00f3lidos e 10 ocos) foram esterilizados em autoclave, formando o Grupo 1. Os demais (10 s\u00f3lidos e 10 ocos) foram esterilizados em OE, compondo o Grupo 2. Ap\u00f3s a esteriliza\u00e7\u00e3o, os objetos foram armazenados e encaminhados para cultura. Objetos ocos de ambos os grupos foram quebrados durante a semeadura, comunicando o espa\u00e7o morto com o meio de cultura.

No grupo 2 (OE) o crescimento ocorreu em 20% dos objetos ocos, com aus\u00eancia de crescimento bacteriano nos objetos s\u00f3lidos (100% de amostras negativas). A bact\u00e9ria isolada nos casos positivos foi Staphylococcus Gram positivo n\u00e3o produtor de coagulase.<\/jats:p><jats:p>\n          Conclus\u00f5es\u2003A esteriliza\u00e7\u00e3o tanto em autoclave quanto pelo OE n\u00e3o foi eficaz para objetos impressos no formato oco. Objetos s\u00f3lidos esterilizados em autoclave n\u00e3o demonstraram 100% de amostras negativas, n\u00e3o sendo seguro no presente ensaio. Aus\u00eancia completa de contamina\u00e7\u00e3o ocorreu apenas com objetos s\u00f3lidos esterilizados pelo OE, sendo a combina\u00e7\u00e3o recomendada pelos
