Most individuals experience bad breath (malodor or halitosis) occasionally, but few people can selfdiagnose when it occurs. Proto - types and initial human trial clinical tests have been completed on a low-cost bad-breath detection device. The detector changes color when the user blows through a tube.
The Kimberly-Clark detection technology uses a wellunderstood chemical reaction that is sensitive to low concentrations of amines and thiols — indicators of halitosis. Individual detectors can be manufactured for very low cost, in the range of a few US cents. The devices have been efficacy tested in human trials, and initial packaging studies have been carried out.
