title: Oral pathology in untreated coeliac [corrected] disease.
abstract: BACKGROUND
  Many coeliac disease patients with atypical symptoms remain undiagnosed.
  
  
  OBJECTIVE
  To examine the frequency of oral lesions in coeliac disease patients and to assess their usefulness in making coeliac disease diagnosis.
  
  
  METHODS
  One hundred and ninety-seven coeliac disease patients and 413 controls were recruited and the oral examination was performed.
  
  
  RESULTS
  Forty-six out of 197 coeliac disease patients (23%) were found to have enamel defects vs. 9% in controls (P < 0.0001). Clinical delayed eruption was observed in 26% of the pediatric coeliac disease patients vs. 7% of the controls (P < 0.0001). The prevalence of oral soft tissues lesions was 42% in the coeliac disease patients and 2% in controls (P < 0.0001). Recurrent aphthous stomatitis disappeared in 89% of the patients after 1 year of gluten-free diet. Multi-logistic analysis selected the following variables as the most meaningful in coeliac disease patients: dental enamel defects (OR = 2.652 CI = 1.427-4.926) and soft tissue lesions (OR = 41.667, CI = 18.868-90.909). Artificial Neural Networks methodology showed that oral soft tissue lesions have sensitivity = 42%, specificity = 98% and test accuracy = 83% in coeliac disease diagnosis.
  
  
  CONCLUSIONS
  The overall prevalence of oral soft tissue lesions was higher in coeliac disease patients (42%) than in controls. However, the positive-predictive value of these lesions for coeliac disease diagnosis was low.
