  3. Notes:
  4. (R): Reference category
  5. (*): p < 0.05 compared to the Reference Category.
  6. (#): Adjusted Missing is the sum of the observed number of missing teeth (32) and number of residual roots (32) to yield an estimate of Total "Functional" Missing Teeth.
  7. ($): Functional Edentulous defined as having either fully missing teeth and/or residual roots present.
