口臭被定义为令人不快的口腔气味，是公众关注的问题。口臭通常通过感官检查和气相色谱分析口臭的主要来源，挥发性硫化合物，如硫化氢、甲基硫醇和二甲基硫化物来诊断。气相色谱法需要大规模的系统和较长的运行时间。我们研究了使用氧化锌薄膜半导体传感器测量口腔空气中痕量挥发性硫化合物。用特氟龙袋采集21名志愿者的口腔空气样本，采用监测分析、气相色谱分析和3名裁判员的感官检查3种方法进行分析。监测仪的读数与气相色谱法测定的总挥发性硫化合物值（r = 0.75, P < 0.01）和裁判的感官评分（r = 0.76, P < 0.01）相关。感官评分与气相色谱值呈正相关（r = 0.71, P < 0.01）。这些结果表明，这种新型的氧化锌薄膜半导体传感器监测仪可用于口臭的诊断。它的体积小，操作简单，可以用于日常的椅子边研究和口臭的实地调查。
Halitosis, defined as unpleasant oral odor, is a concern among the general public. Halitosis is generally diagnosed by organoleptic examination and by gas chromatographic analysis of the main source of halitosis, volatile sulfur compounds, such as hydrogen sulfide, methyl mercaptan, and dimethyl sulfide. Gas chromatography requires a large-scale system and a long running time. We investigated the use of a zinc-oxide thin film semiconductor sensor for measuring trace volatile sulfur compounds in mouth air. Mouth air samples collected in teflon bags from 21 volunteers were analyzed by 3 methods: the monitor analysis, gas chromatography, and organoleptic examination by 3 judges. The readings of the monitor were correlated with the values of the total volatile sulfur compounds measured by gas chromatography (r = 0.75, P < 0.01) and also with the organoleptic scores given by the judges (r = 0.76, P < 0.01). The organoleptic scores were correlated with the gas chromatographic values (r = 0.71, P < 0.01). These results suggest that this new monitor with a zinc-oxide thin film semiconductor sensor may be used for the diagnosis of halitosis. Its small size and simplicity of handling may enable its use for routine chair-side study and field surveys of halitosis.
