摘　　要：目的:评价新型便携式气相色谱仪(GC-SCS)与常用口臭检测方法检测口臭的相关性。方法:选择55例全身健康的受试者,由嗅辨员对其进行感官分析评分,同时采用便携式硫化物检测仪(Halimeter^(Tm))检测口腔可挥发性硫化物总量,应用GC-SCS检测3种挥发性硫化物含量。所得结果采用SPSS11.5软件包进行Pearson和Spearman相关性分析。结果:GC-SCS所测硫化氢、甲硫醇及VSCs总量与感官分析法均值之间的相关系数分别为0.486、0.529和0.491(P<0.01)。GC-SCS所测硫化氢、甲硫醇及VSCs总量与Halimetr所测VSCs含量之间的相关系数分别为0.458、0.522和0.436(P<0.01)。结论:GC-SCS检测所得的挥发性硫化物的含量与感官分析得分、Halimeter检测所得挥发性硫化物总量之间的相关性较好,是一种很有潜力的口臭检测方法。PURPOSE： To evaluate the relationship between a portable gas chromatography（GC-SCS） and other methods to diagnose halitosis. METHODS： Fifty-five systemic healthy subjects were involved in the study.Halitosis intensity was examined by two experienced judges using organoleptic method. Halimeter Was used to evaluate the concentrations of volatile sulfur compounds while GC-SCS was used to tell the volume of each volatile sulfur compound. SPSS11.5 software package was used for Pearson and Spearman correlation analysis. RESULTS： The results showed that the concentration of hydrogen sulfide, methyl mercaptan and total VSCs measured by GC-SCS was significantly related to the organoleptic scores with the correlational coefficients of 0.486, 0.529 and 0.491, respectively （P〈0.01）. There was no statistically significant relationship between the dimethyl sulfide values and the organoleptic scores. The VSCs value measured by Halimeter was significantly related to the concentration of hydrogen sulfide, methyl mercaptan and total VSCs measured by GC-SCS with the correlational coefficients of 0.458, 0.522 and 0.436, respectively （P〈0.01）. CONCLUSIONS： GC-SCS relates well with organoleptic method and Halimter. It is suggested that GC-SCS may be a good way to diagnose halitosis.
