RESUMO

OBJECTIVES:

The purpose of this in vitro study was to evaluate the effectiveness of different antisepticsfor decontamination of gutta-percha cones. MATERIALS AND

METHODS:

Thirty-six cones werecontaminated with standardized pure cultures of six different microorganisms Staphylococcus aureus,Enterococcus faecalis, Escherichia coli, Klebsiella pneumoniae and Candida albicans. The cones were treated forfive 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 themicroorganisms, except for Candida albicans. For this microorganism, the best results were obtainedwith 3% sodium hypochlorite and 5% citric acid; these two solutions showed moderate activity onother microorganisms. Chlorohexidine was not effective on any of the microorganisms.
ABSTRACT

OBJETIVOS:

Neste trabalho avaliou-se a atividade antimicrobiana in vitro de diferentessoluções antissépticas na desinfecção de cones de guta-percha.

MATERIAIS E MÉTODOS:

Trinta e seis cones de guta-percha foram contaminados com culturas puras de diferentesmicrorganismos Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, Klebsiellapneumoniae e Candida albicans. Os cones foram imersos em diferentes soluções antissépticasálcool 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 maiseficaz sobre todos os microrganismos, exceto sobre a C. albicans. Sobre esta, o mais eficazfoi o hipoclorito de sódio a 3 %, mostrando moderada eficácia sobre os restantesmicrorganismos, tal como o ácido cítrico. A clorhexidina não mostrou eficácia sobre qualquerdos microrganismos, nestas condições experimentais.
