ACTA ODONTOLOGICA SCANDINAVICA, vol.74, no.5, pp.380-384, 2016 (Journal Indexed in SCI)
Objective: Three sources of halitosis exist, potentially in any combination: mouth, nasal cavity or alveolar breath. There has been no universally accepted protocol which differentiates and quantifies each odour source separately. In this study a new gas measurement protocol is described and tested to determine whether each odour source can be separately detected without contamination.
