Intra‐ and extra‐oral halitosis: finding of a new form of extra‐oral blood‐borne halitosis caused by dimethyl sulphide

Abstract

Our study provides evidence that the VSC, CH(3)SH and to a lesser extent H(2)S are the main contributors to intra-oral halitosis and that CH(3)SCH(3) is the main contributor to extra-oral or blood-borne halitosis, due to a hitherto unknown metabolic disorder.
