Halitosis prevention campaign: a report of oral health promotion activities in Japan.

A local dental association, Hakodate Dental Association, has been conducting an oral health promotion campaign, 'Good-bye Bad Breath', in a local community since April 1998. The purpose of this campaign was not only to prevent oral malodour but also to raise people's awareness about oral health. Oral health education has been provided at schools and through television commercials, radio programmes and newspaper articles. Campaign posters and leaflets on bad breath have also been distributed to drug stores, medical clinics and schools, as well as dental clinics. It has been emphasised that oral malodour is a preventable condition and that the dentist can provide adequate advice and suitable treatment. Medical and pharmaceutical associations have cooperated with the Dental Association in running the campaign. Dental care was provided free of charge to the local residents. The free services provided included the assessment of oral malodour using a portable sulphide detector, instructional programmes, and consultations with dentists. This campaign offered a good opportunity to encourage people to visit the dentist for regular check-ups. The number of regular check-ups and halitosis patients has increased in 70% of the clinics belonging to the Dental Association.
