ACTA ODONTOLOGICA SCANDINAVICA, cilt.74, sa.5, ss.380-384, 2016 (SCI-Expanded)
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.
