  1. aNumber of permanent teeth missing.
  2. btotal surfaces with coronal decay.
  3. cDMFT score (decayed, missing, and filled teeth) based on teeth excluding third molars.
  4. dCompare the number of genera in subjects with and without complete loss of teeth.
  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 P value is less than 0.05.
