To examine the effects ofCandidaon halitosis, the carrier state ofCandidawas examined in patients who made a visit with a chief complaint of halitosis.Methods. Subjects were 123 patients (42 males and 81 females) who visited our clinic, with a chief complaint of halitosis. Their average age was 45.8 years. To examine halitosis, an organoleptic test was conducted, and volatile sulfur compounds (VSCs) were measured by gas chromatography. Tongue-coating samples collected at the initial visit were cultured in CHROMagarCandidamedium. The results of aCandidaculture test, an organoleptic test, and VSC measurements were examined.Results. The male-to-female ratio of the patients was about 1 : 2. Patients with severe halitosis accounted for less than 20%. In theCandidaculture test, the positive rate was about 25.2%, andC. albicanswas the most frequently detected. Two kinds ofCandidaspecies were detected in 75% (6/8) of the stronglyCandida-positive group. The VSC measurements were correlated with theCandidaculture test results. Methyl mercaptan concentration was higher in the stronglyC. albicans-positive group or the subjects having two kinds ofCandidaspecies.Conclusion. We suggest that imbalance of oral microbial community exists in the stronglyCandida-positive group.
