Criteria
Subjectively confirmed halitosis
As detected by attending clinicians (organoleptic method). Smelling air from both the nose and the mouth is important, as malodour detectable from the nose alone (asking the patient to breathe while the mouth is closed) is likely to arise from the nose or sinuses.[8] Clinical assessments should be performed by 2 different examiners.[26]
Both the patient and the examiner should refrain from drinking coffee, tea, or juice, as well as from smoking and using scented cosmetics, before the assessment.[7]
Objectively confirmed halitosis
Volatile sulfur compounds, diamines, and/or short-chain fatty acids in exhaled air, as detected by sulfide monitors or gas chromatography.
