At the Second International Workshop on Oral Malodor, the organizing committee, as well as participants, agreed on establishment of the International Society for Breath Odor Research (ISBOR). International Conference for Breath Odor Research is held every two years (the Sixth International Conference on Breath Odor is slated for April 20th-22nd 2004 in London). Leading scientists and clinicians in this field are invited to give the lectures or continuing educations. Diagnosis, treatment, clinical natures, biochemistry, microbiology, psychology, behavioral sciences and the toxicology of oral malodor are discussed. Individual membership in the Society is $100 US per 2 years ($40 US for students).  We anticipate that ISBOR members will receive a discount on registration fees to International Meetings.
