Dental erosion, an extraesophageal manifestation of gastroesophageal reflux disease. The experience of a center for digestive physiology in Southeastern Mexico.
BACKGROUND
Dental erosion (DE) is the loss of the hard tissues of the tooth produced by the action of gastric juice, pepsin and acid on the dental enamel, its frequency ranges from 5 to 53.41 %. In Mexico there are no reports on the frequency and possible association.


OBJECTIVE
To establish the prevalence of dental erosion and its relationship to GERD.


METHODS
Prospective, observational, descriptive and comparative study was conducted in 60 patients diagnosed with GERD and 60 healthy patients at the Institute of Medical and Biological Research of the Universidad Veracruzana in Veracruz city. Anthropometric characteristics, dietary habits, oral hygiene, alcohol consumption, smoking, ED index and Index of decayed/missing dental pieces/sealed and correlation between severity of ED and GERD were analyzed.


RESULTS
78.67 % of patients with GERD had ED, 23.33 % corresponded to grade 0, 41.67 % to N1, N2 and 23.33 % to 11.67 % to N3. Predominance of females (2,3:1). The mean age was 50.92 +/- 13.52 years. The severity of dental erosion was significantly related to the severity of reflux, halitosis, CPO index and poor eating habits. There was no statistically significant difference in the other variables analyzed.


CONCLUSIONS
Dental erosion has a high frequency in patients with GERD and reflux characteristics are directly related to their severity and therefore should be considered as a manifestation of GERD extraesophageal.
