Abstract : Hypochlorous acid is a weak acid with the chemical formula HClO. It forms when chlorine dissolves in water. HClO is an acid involving a polyatomic ion. HClO is used as a bleach, oxidizer, deodorant, and disinfectant. CampherTM contains 80% HClO and is used as a food disinfectant, deodorant, air cleaner, and in instrument and package cleaner systems. The purpose of this study was to examine the efficacy of CampherTM as a root canal irrigant in endodontics. Both pH 6.5 and pH 7.0 CampherTM were examined for bactericidal effect and cytotoxicity. Obligative anaerobic bacteria were completely inhibited by applying CampherTM for 1 minute, and facultative bacteria was inhibited 10−2~10−3 by CampherTM for 1 minute in bactericidal effect. The growth of oral epithelial cells was not affected by CampherTM for 48 hours. Both bactericidal effect and cytotoxicity did not vary with the different pH of CampherTM. These results suggested that CampherTM has a bactericidal effect and no cytotoxicity, and could be useful as a root canal irrigant.
