Epidemiology of halitosis

  • Little epidemiological data are available and these are mostly based on patient interviews. Critical evaluation of these data is necessary because of the subjective ratings used.

Epidemiological studies have suggested:

24% of the Japanese population have oral malodour

(Miyazaki et al. 1995).

76% of German dentists have oral malodour once in a while and 7% have permanently oral malodour; 58% know a colleague suffering from oral malodour (Seemann 1999).

up to 50% of the population suffer from oral malodour with varying degrees of intensity and causes (from a survey of members of the American Dental Society) (Quirynen et al. 2002b).

25% of European, American and Japanese populations have perceivable oral malodour and 6% have permanent oral malodour (Filippi & Meyer 2004).

  • There are no apparent differences in the prevalence or intensity between men and women, but halitosis increases with age.
  • In a telephone survey from the US, it was found that 60% of women and 50% of men regularly use products besides toothpastes for breath refreshment (Rosenberg 1994).
  • Almost $1 billion a year is spent in the US on products to manage bad breath (Quirynen et al. 2002b).
