Title in Portuguese
Avaliação da contaminação microbiana de brocas para desgaste de acrílico
Keywords in Portuguese
Brocas
Controle de infecção cruzada
Abstract in Portuguese
As brocas para desgaste de acrílico são instrumentos semi-críticos, no entanto, seu potencial de infecção cruzada tem sido menosprezado. O objetivo deste trabalho foi verificar a presença de microrganismos em brocas para desgaste de acrílico, consideradas prontas para uso, pertencentes a 80 graduandos da FORP-USP. Foi aplicado questionário abordando métodos de controle de infecção adotados para este instrumental e os microrganismos isolados foram identificados e submetidos a teste de sensibilidade a 12 agentes antimicrobianos. Apesar dos alunos conhecerem os métodos preconizados para a descontaminação das brocas, verificou-se um alto índice de contaminação (36,3%), sendo que algumas brocas estavam contaminadas por mais de um microrganismo. Foram isolados cocos e bacilos gram-positivos e bacilos gram-negativos, resistentes a antibióticos comumente utilizados em Odontologia como a penicilina, clindamicina e a eritromicina

Cross infection control
Abstract in English
Acrylic resin burs are semi-critical instruments and have been overlooked in infection control. The purpose of this study was to verify the presence of microrganisms in acrylic resin burs, that were ready to be used, ffom 80 graduation students at FORP-USP. A survey on methods of infection control applied to acrylic resin burs was conducted and the isolates were identified and tested against 12 antimicrobial agents. Although the students know how to proceed with the burs, there was a high contamination percentage (36,3%) and some burs were contaminated with more than one species. There were isolated gram-positive cocci and bacilli and gram-negative bacilli resistants to antibiotics commonly used in Dentistry like penicillin, clindamicin and eritromicin
