摘要: Background: Volatile sulfur compounds (VSCs) in oral air are the only type of gases correlated with strength malodor. We developed a compact and simple gas chromatograph (GC) equipped newly invented indium oxide semiconductor sensor (SCS) for measuring concentrations VSCs mouth air. have assessed correlation between measurements GC-SCS those regular GC. Methods: Oral samples from randomly selected volunteers were analyzed both GC flame photometric detector (FPD), which is specific to VSCs, compared obtained by GC-FPD. Subsequently, before after mouthrinsing 5% ethanol mouthwash determine effect on VSC GC-SCS. Results: There strong correlations determined using these two chromatography methods (hydrogen sulfide, R = 0.821, P <0.0001; methyl mercaptan, 0.870, dimethyl 0.770, <0.0001). Although can differentiate mouthrinsing, demonstrated higher values than GC-FPD; however, this discrepancy improved over time due reduced ethanol. Conclusion: The results suggest that may be useful diagnosis halitosis. J Periodontol 2006;77:1142-1147.
