Over the last twenty-five years there has been extensive research on the subject of periodontal disease. The presence of gingival inflammation creates debris composed of polypeptide chains. These polypeptide chains are the major contributing factor in halitosis. Found in the breath of halitosis patients are compounds known as volatile sulfur compounds (VSC). The presence of VSC's have been found to breakdown and increase permeability of gingival tissue allowing bacterial toxins to enter the gums. As the severity of periodontal breakdown occurs, the presence of VSC's increases. If VSC's reach a great enough concentration, deepening pockets form in the gum tissue, and the downward spiral begins. Research has found that oxidizing the sulfur bonds with one of the safest yet most powerful oxidizers available, chlorine dioxide, stops the downward spiral effect. Chlorine dioxide has been used by industries for years as a disinfectant and deodorizer.
