The association between coeliac disease and periodontitis: Results from NHANES 2009-2012.

ABSTRACT: AIM:To investigate whether coeliac disease (CD) was associated with periodontitis among a nationally representative sample of US adults. MATERIALS AND METHODS:The National Health and Nutrition Examination Survey (NHANES) 2009-2012 enrolled 6,661 subjects with full-mouth periodontal examination and serological testing for antitissue transglutaminase (tTg) and antiendomysial (EMA) antibodies. CD was defined as (i) self-reported physician diagnosis while on a gluten-free diet; or (ii) tTg levels >10.0 U/ml and positive EMA results. Positive serology without self-reported diagnosis was defined as undiagnosed CD (UdxCD). Periodontitis was defined according to the CDC/AAP definition. Multivariable linear and logistic models were used to regress the mean probing depth (PD) or attachment loss (AL) outcomes across CD categories (none, diagnosed and undiagnosed). RESULTS:The prevalence of moderate/severe periodontitis and diagnosed/undiagnosed CD was 40% and 0.74%, respectively. Mean AL was lower among those with CD although results were not statistically significant (p = .67). The odds of periodontitis among individuals with diagnosed and undiagnosed CD were: 0.5(0.22, 1.16) and 0.62(0.1, 3.75), respectively. Mean PD levels among those without CD or with diagnosed or undiagnosed CD were 1.49 ± 0.02, 1.36 ± 0.11 and 1.31 ± 0.11 (p = .03). CONCLUSION:CD is associated with modestly lower levels of mean PD but was not associated with mean AL or periodontitis. Larger studies are necessary to enhance precision and strengthen conclusions.
