Abstract/OtherAbstract:
Objective: To evaluate the performance of self-report against the reference standard of clinically-defined periodontitis in rheumatoid arthritis (RA) and osteoarthritis (OA) patients after accounting for factors associated with periodontitis. Methods: Six self-report periodontitis questions were evaluated in RA and OA patients. Questions were validated against a reference standard of severe and moderate-to-severe periodontitis based on full-mouth examination. Multivariable logistic regression was used to evaluate the performance of: 1) self-report alone; 2) age, sex, education, and smoking status; and 3) a combination of the above. Model performance was assessed using the c-statistic. Convergent validity of self-reported 'bone loss/deep pockets' and 'loose teeth' was assessed; associations of self-report with RA disease characteristics were explored. Results: Self-report performed similarly in RA and OA, with individual specificity for periodontitis ≥ 68% and sensitivity between 9.8% and 45%. Question-only models yielded c-statistics of 0.66-0.72 while risk factor-only models yielded c-statistics of 0.74-0.79. The highest performing models incorporated both self-report questions and periodontitis risk factors with c-statistics ≥ 0.79. Greater radiographic alveolar bone loss was observed among participants reporting 'bone loss or deep pockets' (p < 0.001) and 'loose teeth' (p < 0.001). Among RA patients, 'loose teeth', but not other self-report items, was associated with rheumatoid factor positivity (p = 0.047) and higher disease activity (p < 0.001). Conclusion: Patient self-report, when combined with other risk factors, performs well in identifying periodontitis among patients with RA and OA. Self-report questions related to alveolar bone loss exhibit excellent convergent validity in these patient subsets.
