Rapid sterilization of gutta-percha cones with glutaraldehyde.
Five commercially available liquid glutaraldehyde preparations (Glutaron II, Cidex 28, Glutalabor, Banicide, and Anti-G-Plus) were compared for effectiveness in sterilizing gutta-percha cones artificially contaminated with Bacillus subtilis ATCC 6633 spores. Sporicidal activity differed for the various brands of cones, but after 15 min all glutaraldehyde solutions were effective in eliminating the spores. However, three solutions (Cidex 28, Banicide, and Anti-G-Plus) showed sporicidal activity within a shorter time (10 min). All glutaraldehyde solutions tested may be used in endodontic practice for rapid decontamination of gutta-percha cones, thus contributing to the maintenance of the aseptic chain, an essential factor for successful root canal treatment.
