Gastric acid regurgitation in patients with gastro-oesophageal reflux is associated with dental erosion. Dental enamel/dentine demineralisation occurs at pH less than 5.5. In achalasia patients, lactic acid with a minimum pH of 3.5 in the oesophagus results from fermentation of retained food. Authors therefore hypothesised that regurgitation in achalasia patients will produce dental erosion. Subjects were interviewed and dietary factors as cause of dental erosion was excluded. It is more likely that the tooth wear is caused by oesophageal lactic acid than gastric acid.
