Halitosis: the multidisciplinary approach

Halitosis is a common condition, affecting around 25% of the general population. The origin of the problem largely arises from intraoral causes, whereas only a limited number of cases are the result of extra oral or systemic problems. Nevertheless, proper investigation and management of these extra oral causes is important for the total understanding of this phenomenon.Although oral malodour is mostly associated with poor oral hygiene and the presence of gingivitis or even periodontitis, evidence suggests that anaerobic microorganisms present in the tongue coating, are the overwhelming cause of this condition.
