A Bosy

    Journal (Canadian Dental Association)
    |March 1, 1997
    PubMed
    Summary

    Chronic bad breath affects 50% of the population, causing significant social distress. Microorganisms on the tongue and teeth are the primary cause of this persistent oral malodor.

    Area of Science:

    • Oral Health
    • Microbiology
    • Biochemistry

    Background:

    • Oral malodor, or bad breath, is a common condition affecting at least 50% of the population.
    • Chronic halitosis causes significant personal discomfort and social embarrassment.
    • While dental diseases are linked, dentally healthy individuals can also suffer from significant mouth odor.

    Purpose of the Study:

    • To investigate the causes and prevalence of chronic oral malodor.
    • To highlight the ineffectiveness of current remedies in eliminating bad breath.
    • To underscore the need for increased research and effective clinical treatments for halitosis.

    Main Methods:

    • Analysis of volatile sulfur compounds (VSCs) contributing to malodor.
    • Identification of microorganisms responsible for proteolytic activity on the tongue and teeth.
    • Review of existing treatments and their efficacy in controlling oral malodor.

    Main Results:

    • Proteolytic activity by oral microorganisms is the most frequent cause of foul-smelling compounds.
    • Hydrogen sulfide, methyl mercaptan, and organic acids are key compounds in chronic bad breath.
    • Current commercial remedies often fail to effectively eliminate oral malodor despite antibacterial claims.

    Conclusions:

    • Chronic oral malodor is a prevalent and distressing condition.
    • Microbial activity on the tongue and teeth is a primary etiological factor.
    • Further research and improved clinical interventions are necessary for effective halitosis management.
