Abstract

We hypothesized that analysis of mouth air would be indicative of not only periodontal status but also populations of periodontal pathogens in periodontal pockets. Oral malodour and volatile sulphur compounds (VSCs) concentrations in mouth air from 30 subjects were examined by electronic nose, gas chromatography and organoleptic tests. Several periodontal parameters were also recorded. Periodontal pathogens, i.e. P. gingivalis, A. actinomycetemcomitans, T. forsythia, P. intermedia and T. denticola were analyzed in saliva, tongue coating and subgingival plaque by real-time PCR. The following results were obtained. 1.The max probing pocket depth (PD) was significantly correlated with oral malodour expressed as organoleptic score, total mode of electronic nose and CH₃SH/H₂S ratio. 2.Total measurement mode of electronic nose, CH₃SH/H₂S ratios significantly correlated with total level of the microorganisms in subgingival plaque(adjusted R² =0.690，p＜0.027). A significant positive correlation was demonstrated between the actual measurement value and the forecast value of the total level of the five periodontopathic microorganisms in subgingival plaque (R²＝0.447, p＜0.001). Electronic nose measurements or CH₃SH/H₂S ratio would be a practical indicator of periodontal health status. Mouth-air analysis might indicate the level of periodontopathic microorganisms in periodontal pockets. Nihon Shishubyo Gakkai Kaishi (JJpn Soc Periodontol) 56(4)：379-389, 2014.
