  • Specific aims were to determine the prevalence of erosive tooth wear (ETW) in gastroesophageal reflux disease (GERD) and control populations after controlling for other known risk factors (diet, medications, salivary flow rate and buffering capacity) and to survey US and Canadian dental schools regarding their teaching of ETW. ETW was determined for subjects recruited (GERD/Control) using the Basic Erosive Wear Examination (BEWE) index. A survey was also sent to all US and Canadian dental education programs. Results showed that prevalence of ETW in GERD subjects was 51.7% versus 18.2% for controls. ETW worsen with age and was the only co-factor investigated that significantly affected ETW. Although 100% of dental schools in the US and Canada taught dental erosion, only 15.3% of respondents could correctly identify clinical signs of dental erosion, showing that diagnosis of this condition remains unclear. Tooth wear index and diet counselling are also underutilized.
