Resumo (PT): Objectivos: Neste trabalho avaliou-se a actividade antimicrobiana in vitro de diferentes soluções antissépticas na desinfecção de cones de gutta-percha. Materiais e métodos: trinta e seis cones de gutta-percha foram contaminados com culturas puras de diferentes microrganismos: Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae e Candida albicans. Os cones foram imersos em diferentes soluções antissépticas: álcool iodado a 2%, hipoclorito de sódio a 3%, clorhexidina a 0,2% e ácido cítrico a 5%, durante 5 minutos. Resultados: os resultados indicam que o álcool iodado é o mais eficaz sobre todos os microrganismos, excepto a C. albicans. Sobre esta, o mais eficaz foi o hipoclorito de sódio a 3%, mostrando eficácia sobre os restantes microrganismos, tal como o ácido cítrico. A clorhexidina não mostrou eficácia sobre qualquer dos microrganismos, nestas condições experimentais.

Abstract (EN): Objectives: the purpose of this in vitro study was to evaluate the effectiveness of different antiseptics for decotamination of gutta-percha cones. Materials and methods: thirty-six cones were contaminated with standardized pure cultures of six different microorganisms: Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Klebsiella pneumoniae and Candida albicans. The cones were treated for five minutes with different antiseptic solutions: 2% iodine alcohol, 3% sodium hypochlorite, 0.2% chlorohexidine and 5% citric acid. Results: iodine alcohol was the most effective for all the microorganisms, except for Candida albicans. For this microorganism, the best results were obtained with 3% sodium hypochlorite and 5% citric acid; these two solutions showed moderate activity on other microorganisms. Chlorohexidine was not effective on any of the microorganisms.
