| The effectiveness of seven disinfectant compounds used in dentistry for a rapid decontamination of 32 gutta-percha cones adhered with Staphylococcus aureus, Enterococcus faecalis, Escherichia coli strains or Bacillus subtilis spores was compared. Cones were treated with 2% glutaraldehyde, 1% sodium hypochlorite, 70% ethyl alcohol, 1% and 0.3% iodine alcohol, 2% chlorhexidine, 6% hydrogen peroxide, and 10% polyvinylpyrrolidone-iodine, for 1, 5, 10, and 15 minutes. After treatment, each cone was transferred to thioglycollate broth and incubated at 37ºC for 7 days. The products were bactericidal after 1 to 5 minutes and, with exception of ethyl alcohol and iodine-alcohol, sporicidal after 1 to 15 minutes of exposure. Results suggest that chlorhexidine, sodium... |

| This study investigated the effectiveness of detergent and aqueous solutions of 2% chlorhexidine digluconate in decontaminating gutta-percha cones (gpc) contaminated with bacteria, yeast, or bacterial spores. Gutta-percha cones were contaminated with 10(7)-10(8) colony-forming units per milliliter (cfu/ml) of the following test organisms: Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, or Candida albicans. Spores of Bacillus subtilis were also tested. Contaminated gpc were treated with the chlorhexidine solutions for 1, 5, 10, or 15 min. Each cone was then transferred to a tube containing saline and the micoorganisms were recovered after homogenization for cfu determination. Both detergent and aqueous chlorhexidine solutions were effective... |
