感官分析法和便携式硫化物检测仪检测口臭的相关性研究

目的比较感官分析法(鼻测法)和便携式硫化物检测仪(商品名Halimeter)检测口臭之间的准确性和一致性。方法首先对2名嗅辨员进行嗅觉检测试验,以确定其进行感官分析评分的资质。选择86例符合试验条件的受试者,分别用感官分析法评价口臭程度,硫化物检测仪检测口腔挥发性硫化物(VSC)含量,使用SPSS11.0软件分析鼻测法得分均值和VSC水平的关系。结果2名嗅辨员一致性良好,Kappa值达到0.568,P<0.01。鼻测法得分均值与Halimeter检测所得硫化物峰值之间相关系数r=0.538,P<0.01;与硫化物稳定值之间相关系数r=0.546,P<0.01。结论鼻测法得分和Halimeter检测的口腔VSC含量之间存在显著相关关系,提示Halimeter可在一定程度上作为鼻测法的辅助手段,用以检测口臭。

The relationship between two halitosis diagnostic methods:organoleptic test and VSCs measurement by a portable sulfide detector

PURPOSE: To evaluate the relationship between organoleptic(OR) scores and volatile sulfur compounds (VSCs) values measured by a portable sulfide detector(Halimeter). METHODS: Eighty-six subjects were included into the study. The intensity of halitosis was evaluated by two examiners who had been trained to perform this procedure. A portable sulfide detector (Halimeter) was used to examine the values of VSCs in oral cavity. Spearman analysis was used to examine the relationship between the average value of organoleptic scores and VSCs levels. RESULTS: The Kappa value between the two examiners was 0.568, P<0.01.The correlation coefficient between the average values of organoleptic scores and VSCs levels (including maximum and steady values) was 0.538 and 0.546, P<0.01, respectively. CONCLUSIONS: The organoleptic scores were significantly related to VSCs values. It is suggested that Halimeter could be an assistant instrument to diagnose halitosis.
