Background: Heartburn is identically the key symptom of both, gastroesophageal reflux disease (GERD) and functional heartburn (FHB), making the differential diagnosis resource-intensive. Oral manifestations of GERD can be easily examined; therefore, their exploration might be a cheap, widely available, and useful tool in the differentiation of GERD and FHB.
Aim: To evaluate the prevalence of dental erosions (DE) and periodontal diseases (PD) in patients with heartburn and their association with GERD and FHB.
