Correct answer: A — Gastro-oesophageal reflux disease (GORD)
Gastro-oesophageal reflux disease is associated with erosive tooth wear because refluxed gastric contents expose the teeth to intrinsic acid, causing non-bacterial dissolution of enamel and dentine. A systematic review and meta-analysis found that people with GORD or reflux-related symptoms had approximately two- to fourfold greater odds of erosive tooth wear. Crohn disease, ulcerative colitis and coeliac disease can produce oral manifestations, including ulceration or developmental enamel defects, but they do not characteristically cause intrinsic gastric acid-mediated erosion. Irritable bowel syndrome has no characteristic erosive dental complication. Therefore, GORD is the single best answer.
