Abstract

Current approaches to the Treatment of Intra-Oral Halitosis

Chronic halitosis is a rather frequent condition, which in almost 90% of the cases has an intraoral cause. The most prevalent causes are: the presence of tongue coating, gingivitis/periodontitis or a combination of both.

Occurrence of halitosis is mainly due to the presence of volatile sulphur compounds (VSCs) in the air expelled through the oral cavity. These compounds are generated through the protein metabolism of Gram-negative anaerobic bacteria that are primarily harboured in the tongue coating, subgingival/supragingival biofilms and other areas.

Therefore, halitosis therapy aims to lower the total numbers of odourigenic bacteria, to reduce the amount of protein substrates and to neutralise the volatilisation of the malodorous compounds.

Even though mechanical removal/disruption of the tongue and dental biofilms is a necessary step in the treatment of intraoral halitosis, it is not always sufficient to control this condition in the long term. The adjunctive daily use of chemical agents is also normally needed.

In the presentation, the update evidence on the available therapeutic strategies and protocols will be reviewed in detail.
In addition, new therapeutic strategies, such as the use of probiotics, will also be discussed since they have shown promising preliminary results.
