Origin of halitosis
- In almost 90% of cases the cause for halitosis is microbial putrefaction of
– food debris
– defoliated epithelial cells
– saliva
– blood
(Filippi & Meyer 2004, Porter & Scully 2006) (see section “Microbiology and chemistry of oral halitosis”). - Halitosis reflects complex interactions between several oral, mostly anaerobic, gram-negative bacteria.
- There is no specific bacterial strain that is responsible for the condition.
