Oral malodor: philosophical and practical aspects

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.
