The purpose of this study was to develop clinical classification of halitosis with corresponding treatment needs and was to tentatively classify halitosis patients according to the proposed classification. The classification consists of 3 classes (Ⅰ,Ⅱ,andIII) and 3 sub-classes in class I, that is, physiologic halitosis (Class1-a), oral pathologic halitosis (Class 1-b-1), extraoral pathologic halitosis (Class 1-b-2), Pseudo-halitosis (Class 2) and Halitophobia (Class3). Organoleptic scoring, volatile sulfur compounds (VSC) measurements using a portable sulfide monitor (Halimeter; RH-17 series, Interscan) and/or Gas Chromatograph (GC) were carried out for patients with bad breath complaint at the Breath Odor Clinic in the Dental School Hospital, Niigata University. All patients were examined 3 times in different days and diagnosed by average scores or values. There were 215 patients newly registered at the Clinic during the 1st year from April 1, 1998 to 31 March 1999. After excluding patients with incomplete data in their medical records, 210 patients (71 males and 139 females) were classified according to the proposed classification. Numbers (percentages) of patients with physiologic halitosis (Group 1), oral pathologic halitosis (Group 2), extraoral pathologic halitosis (Group 3), pseudo-halitosis (Group4), and halitophobia (Group5) were 43 (20.5%), 78 (37.1%), 7 (3.3%), 74 (35.2%), and 8 (3.8%), respectively. The mean organoleptic scores of patients in Groups 1 (2.1), 2 (2.6) and 3 (2.5) were higher than those in Groups 4 (1.3) and 5 (1.6). The mean VSC values of patients in Groups 1 (169.0ppb), 2 (235.3ppb) and 3 (210.4ppb) were higher than those in Groups 4 (100.5ppb) and 5 (108.9ppb). Relatively higher VSC values were found even in pseudo-halitosis and balitophobia groups although both had lower level of OLS.本論文の目的は、試案した口臭症の臨床病態分類を公表すること、新潟大学歯学部附属病院口臭クリニックに来院した初診患者をこのクライテリアにより分類することである。口臭は官能検査、ガスクロマトグラフィ、ポータブルサルファイドモニターを用い測定した。初診患者210名のうち、真性口臭症が61%(生理的口臭:21%、口腔由来の病的口臭:37%、全身由来の病的口臭:3%)、仮性口臭症が35%、口臭恐怖症が4%であった。分類されたグループ別に平均官能検査スコア(OLS)をみると、生理的口臭症は2.1と真性口臭症の中では低かったが、仮性口臭症(1.3)と口臭恐怖症(1.6)と比べると明らかに高値を示した。口腔由来の病的口臭グループの平均VSC濃度235.3ppbは、生理的口臭(169.0ppb)、仮性口臭症(100.5ppb)、口臭恐怖症(108.9ppb)に対し有意(p<0.01)に高かった。
