Abstract
Abstract The use of stabilized chlorine dioxide as a composition for the treatment and prevention of oral disease and the reduction of oral malodor is disclosed. Chlorine dioxide is an effective anti-plaque agent, anti-gingivitis and anti-periodontitis agent, and also effective to destroy malodorous sulfur compounds. Preferred concentrations are in the range of 0.005% to 2% and the chlorine dioxide may be in the form of a wash or rinse in solution, a soak or as a toothpaste.
