In patients undergoing upper gastrointestinal endoscopy, benign oesophageal strictures were significantly more frequent (p less than 0.01) in those with severe tooth loss than in controls of the same age. This may be because of edentulous patients eating less solid and more liquid food, which would otherwise dilate the lower oesophagus, or poor salivary flow leading to both tooth loss and impaired neutralisation of refluxed gastric acid, or malnutrition. No association was found, however, between either oesophagitis or hiatus hernia and dentition.
在接受上消化道内镜检查的患者中，严重牙齿缺失患者的良性食管狭窄发生率显著高于同年龄对照组（p<0.01）。这可能是因为无牙患者食用的固体食物较少而液体食物较多，否则会扩张食管下段，或者唾液分泌不足导致牙齿缺失以及反流胃酸的中和功能受损，又或者是营养不良。然而，未发现食管炎或食管裂孔疝与牙列之间存在关联。
