Aim To examine an organoleptic scoring method ( OLS ) whereby the sample is collected by negative pressure in a syringe and is subsequently smelled and rated away from the patient. Materials and Methods Data of 476 patients visiting a specialized halitosis clinic in Leuven (Belgium) were reviewed retrospectively. Organoleptic (with the classic and with the negative‐pressure method) and instrumental (with the Halimeter® and OralChroma ™ ) ratings of breath odour were retrieved from patient files together with the final diagnosis. The correlations between the different methods were examined (Spearman correlation coefficient) as well as the positive ( PPV ) and negative predictive value ( NPV ), sensitivity and specificity of all methods. Results Both methods of OLS correlated similarly with the instrumental measurements (Halimeter® and OralChroma ™ ). Analysis of PPV , NPV , sensitivity and specificity of both methods of examination showed that the negative‐pressure method performed best. Conclusion The negative‐pressure method is a valid method for organoleptic scoring of the breath odour and performs as good as the classic organoleptic method.
