Halitosis is known as unpleasant oral odor and is a health concern among the general public. Previously, we reported on a new portable monitor with a zinc-oxide, thin-film, semiconductor sensor which demonstrated simplicity of handling, high reproducibility and correspondence for organoleptic assessment. The results suggested its usefulness for the diagnosis of halitosis. Using the monitor, oral air samples of 94 subjects were measured in a field survey, and the values were compared with the organoleptic rates of corresponding samples assessed by two judges. A highly significant correlation (r=0.824, P<0.01) was demonstrated between the measures obtained by the two methods. The results suggest that the monitor is useful for not only a clinical study but also a field study of halitosis.
