It is estimated that approximately 85% of all halitosis cases have their origin within the mouth; of these 50% are caused by tongue residues. Tongue cleaning has gained importance as a a means of halitosis management. This investigation compared the efficacy of two methods for tongue cleaning: using a tongue scraper or using a soft-bristle toothbrush.The tongue coating was removed by both methods, however the tongue scraper performed better by removing 75% of the oral malodor causing volatile sulfur compounds, while the toothbrush only showed a 45% reduction of the same compounds.
