Oral and dental manifestations in gastroesophageal reflux disease.

One hundred seventeen patients with reflux disease were examined with respect to the severity of their disease and oral, dental, and salivary findings. Twenty-eight patients had dental erosion, whereas the remaining 89 patients did not. No mucosal changes could be observed to be linked with the reflux disease. In the mean, the patients with erosion were older (54 versus 49 years), and the mean duration of their reflux disease was longer in comparison to those without erosion (17 versus 11 years, respectively). The severity of the reflux disease was more marked among patients with erosion than in those without as assessed by esophagogastroduodenoscopy, the Maratka classification, histologic examination of gastric and esophageal biopsy specimens, and 24-hour esophageal pH monitoring. No statistically significant differences were observed between the groups in any salivary parameters studied, although the number of patients with low salivary-buffering capacity was higher among those with erosion than among those without. Patients taking beta-blocking agents or tranquilizers had more erosion than those who did not take these medications. The severity of the reflux disease was not associated with any subjective symptoms in the mouth or pharynx. The frequency of consumption of acidic drinks and foodstuffs as determined by a questionnaire did not differ between the patients with and without dental erosion. Thus severe reflux disease of long duration was found to be potentially detrimental to the teeth, whereas milder forms of the disease need not cause dental side effects.
