It is well known that acid regurgitated from the stomach into the mouth will erode teeth. Conditions such as anorexia and bulimia nervosa, chronic alcoholism and gastric disturbances cause palatal dental erosion. The common factor in these conditions is the role played by the stomach and oesophagus in the acid movement. Acid moving through the lower oesophageal sphincter into the oesophagus is described as gastro-oesophageal reflux (GOR). In some patients the acid movement becomes chronic, painful and requires treatment and is termed gastro-oesophageal reflux disease (GORD). It is felt by many gastroenterologists that GORD is a failure of the anti-reflux mechanism, which is predominantly controlled by the lower oesophageal sphincter (LOS). Regurgitation is the reflux of gastric juice through the upper oesophageal sphincter and into the oral cavity. Once the acid has reached the mouth the potential exists for damage to the teeth. This paper reviews the role of GOR, GORD and regurgitation in the aetiology of dental erosion.
众所周知，从胃反流至口腔的胃酸会侵蚀牙齿。诸如神经性厌食症、神经性贪食症、慢性酒精中毒和胃部紊乱等病症会导致腭部牙齿侵蚀。这些病症的共同因素是胃和食管在酸液移动中所起的作用。酸液通过食管下括约肌进入食管被称为胃食管反流（GOR）。在一些患者中，酸液移动会变为慢性、疼痛性的，需要进行治疗，这被称为胃食管反流病（GORD）。许多胃肠病学家认为，GORD是抗反流机制出现故障，而该机制主要由食管下括约肌（LOS）控制。反流是指胃液通过食管上括约肌反流至口腔。一旦胃酸到达口腔，就有可能对牙齿造成损害。本文综述了GOR、GORD和反流在牙齿侵蚀病因学中的作用。
