The present article reviews the current knowledge of halitosis with particular emphasis upon the interplay of diet and disease of the gastrointestinal tract upon oral malodour.
Transient-altered breath smell usually reflects the effects of foodstuffs, whereas longstanding halitosis is almost always because of oral disease such as gingivitis or periodontitis. There is, however, increasing evidence that upper gastrointestinal tract disease may give rise to halitosis and that extracts of foodstuffs may be future therapeutic agents for the treatment of halitosis derived from the mouth or upper gastrointestinal tract.
There is some interplay between the halitosis and the gastrointestinal tract, and it is possible that the therapy of halitosis may be aided by investigations of the effects of foodstuffs upon bacteria that give rise to volatile sulphur compounds.
本文综述了口臭的现有知识，特别强调了饮食与胃肠道疾病对口腔异味的相互作用。
短暂改变的口气通常反映了食物的影响，而长期口臭几乎总是由于口腔疾病，如牙龈炎或牙周炎。然而，越来越多的证据表明，上消化道疾病也可能导致口臭，食物提取物可能成为未来治疗口腔或上消化道来源口臭的治疗药物。
口臭与胃肠道之间存在一定的相互作用，通过研究食物对产生挥发性硫化合物的细菌的影响，可能有助于口臭的治疗。
