Summary

Medical center personnel were screened organoleptically for bad breath by 2 investigators using Rosenberg scale 0-5, and measurement of breath sample in portable gas chromatograph. With a threshold score of 2 or more, or 75parts per billion(ppb) hydrogen sulfide(H2S), subjects invited to enter clinical trial of the mechanical effect of daily tongue scraping with the adjunctive use of 0.12% chlorhexidine gluconate mouthwash or 0.1% stabilized chlorine dioxide mouthwash. Subjects randomly assigned in double-blind trial for one week. The null hypothesis is there will be no difference between the two rinses as adjuncts to tongue scraping.
