口源性口臭检测指标的初步研究

目的：探讨寻找鼻测法替代检测手段的可能性.方法：选取56例医学院在校学生作为研究对象,使用Spearman法和Pearson法,分析鼻测法与口腔可挥发性含硫化合物、唾液pH、舌背微生物培养、唾液尸胺等检测结果间的相关关系.结果：口腔可挥发性含硫化合物（rMax=0.537,P＜0.01;r稳定值=0.572,P＜0.01）、唾液pH（r=0.344,P＜0.01）、唾液尸胺浓度（r=0.352,P＜0.01）、口腔卫生指数的检测结果（r=0.323,P＜0.05）、唾液兼性厌氧培养菌落计数（r=0.398,P＜0.01）、舌背兼性厌氧培养菌落计数（r=0.293,P＜0.05）及舌背专性厌氧培养菌落计数结果（r=0.473,P＜0.01）均与鼻测法结果呈正相关,但相关性均较弱.结论：任一单一指标均不能替代鼻测法对口臭进行诊断.

Preliminary study of the clinical indices for halitosis

PURPOSE: To explore the possibility of using other clinical indices to detect halitosis in stead of organoleptic test(OST). MEATHODS: 56 medical students were chosen as the subjects. Spearman test and Pearson test were used to analyze the relationship between OST results and other indices. RESULTS: It was found that the value of volatile sulfur compounds (VSC) (rMax=0.537,P<0.01;rStable=0.572,P<0.01), pH of the saliva(r=0.344,P<0.01), cadaverine(r=0.352,P< 0.01), OHI-S(r=0.323,P<0.05), colonies of facultative anaerobe from saliva (r=0.398,P<0.01) and tongue dorsum(r= 0.293,P<0.05), colonies of anaerobe from tongue dorsum(r=0.473,P<0.01) correlated positively with OST score, but the coefficients were all low. CONCLUSION: It is not practical and feasible to replace OST with any other single index at present. Supported by Research Fund of Shanghai Municipal Health Bureau (Grant No. 034085).
