    recession is measured form the ______ to the ______ ________ ______.
    • free
    • gingiva
    • CEJ
    • free gingival crest
  4. what separates the attached gingiva from the marginal (free) gingiva?
    free gingival groove
  5. what prevents food impaction?
    interdental papilla
  6. it is between the teeth and also known as interdental papilla.
    interdental gingiva
  7. where is the col located?
    apical to the contact area
  8. a concavity in the interdental papilla that forms between the lingual and facial gingival surfaces
  9. what three things describe attached gingiva?
    • pink
    • stippling
    • immobile
  10. a thick layer of parakeratinized epithelium which blocks the vascular supply in the lamina propria
    pink attached gingiva
  11. tall narrow papilla in the lamina propria that pull on the epithelium and cause dimples
  12. when there is swelling in the gingiva, what goes away?
  13. attached gingiva is ________ and firmly attached to the ______ beneath it
    • immobile
    • bone
  14. why are gums red when someone has perio?
    there is more blood supply which makes it more visible
  15. what two things are present when there is inflammation?
    • erythema
    • edema
  16. pain, heat, erythema, edema, loss of function are examples of:
  17. the tissue is red because of increased blood flow is called:
  18. edema is when the _________ papilla is ________ as it is filled with ______ fluid. this edema may cause the tissue to loose its ________.
    • interdental
    • enlarged
    • tissue
    • stippling
  19. when gums "pull down" they expose the root surface. this is called:
    gingival recession
  20. in gingival recession, the ______ gingival margin starts to move ______. usually exposing _______ which can cause _________.

    • cementum
    • sensitivity
  21. what five things can cause gingival recession?
    • perio disease
    • tooth position
    • incorrect toothbrushing
    • occlusal stress
    • strong frenal attachments
  22. what is measured from the CEJ to the free gingival margin?
    gingival recession
  23. overgrowth of the interdental papilla
    gingival hyperplasia
  24. gingival hyperplasia is usually caused by poor ______ ________ and certain ________
