Abstract
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.

METHODS

A total of 116 [M/F: 51/65, mean age: 54 (17-80) years] consecutive patients with heartburn were enrolled for detailed esophageal function and orodental examinations.

RESULTS

Dental disorders were detected in 89% (103/116). Patients with PD + DE had significantly more often pathologic reflux (90.0% vs 27.8%; P < 0.05), higher esophagitis scores (1.8 vs 0.9; P < 0.05), and a significantly different mean impedance curve (P = 0.04) than those without any dental diseases. The opposite approach established that patients with GERD had significantly higher prevalence of DE and PD, especially if both were present (28.9% vs 2.0%; P < 0.01), more severe PD (1.5 vs 1.0; P < 0.01), and longer history of heartburn (15 years vs 9 years; P < 0.01) than those with FHB.

CONCLUSION

The dental evaluation of patients with heartburn seems to be useful in the differential diagnosis of GERD and FHB. Among the studied parameters, the co-appearance of DE and PD seems to be the best predictor of GERD, whereas the absence of dental disorders was mostly observed in FHB.
