[Development of breath detector for halitosis (1). Theory and method]

A Breath Detector was developed and its clinical application was investigated. It is very difficult to judge how one's own breath smells. The sense of smell is the most unreliable of the senses and has still not been scientifically clarified. Everyone who tried to accurately express the strength and the character of some smell will be puzzled to see the difficulty of expression. A smell on one's breath is actually impossible to expressed on the same scale as for weight or length. On a laboratory basis, it is certainly possible to clarify the concentration and the mass of some odor by using graphic or numerical values with Gas chromatography. However such measuring methods at laboratories are not available in our daily clinical life when it is required to check easily, anytime and anywhere. In consideration of the above, We believe that this Breath Detector with a built-in small special gas sensor will act a substitute for an analyzer, and that the device can express how strong the smell on one's breath is. Therefore we recommend Breath Detector as a product many patients have been waiting for.
