  1. aNumber of permanent teeth missing, including third molars.
  2. bTotal surfaces with coronal decay.
  3. cDMFT (decayed, missing, and filled teeth) score, based on teeth excluding third molars.
  4. dComparing those subjects with and without any remaining teeth (logistic model).
  5. eBleeding of probe extent score, percent of probed sites with bleeding.
  6. fLoss of attachment extent score, percent of probed sites with loss of attachment > =3 mm.
  7. gComparing those with and without periodontitis by the periodontitis summary estimate (logistic model).
  8. hCoefficient and p value based on adjusted logistic regression model.
  9. All linear and logistic models adjusted for age, gender, smoking status, antibiotic use in the last 3 months and sampling device type.
  10. Bolded if the P value is less than 0.05.
