Dental erosion, which is the irreversible loss of tooth substance that does not involve bacteria ranging from a minimal loss of surface enamel to the partial or complete exposure of dentine by a chemical process.
Dental erosion is acknowledged as an established extra-esophageal manifestation of gastro-esophageal reflux disease (GERD).

However, the real impact of GERD in the genesis of this lesion remains unclear.
Dr Pace and colleagues from Italy reviewed the existing literature to assess the relationship between dental erosion and GERD.
The team identified studies that assessed the prevalence of dental erosion in individuals with GERD or vice versa in Medline and the Cochrane Controlled Trials Register via a systematic research strategy.
The researchers found 17 studies that met the selection criteria.
Studies, however, differed greatly as far as design, population methods of diagnosing GERD, duration of follow-up and, consequently, findings.
The team found the median prevalence of dental erosion in GERD patients was 24%.
The median prevalence of GERD in dental erosion adults patients was 33%, and 17% in the pediatric population.
The majority of studies showed that children with GERD are at increased risk of developing dental erosions in comparison with healthy subjects, as are people with intellectual disabilities.
Dr Pace's team concluded, "This systematic review shows that there is a strong association between GERD and dental erosion."
"The severity of dental erosion's seems to be correlated with the presence of GERD symptoms, and also, at least in adults, with the severity of proximal esophageal or oral exposure to an acidic pH."
"The inspection of the oral cavity in search for dental erosions should become routine in patients with GERD."
