  1. junction between the tooth surface and gingival tissues
    dentogingival junction
  2. sulcular epithelium + junctional epithelium = ___________
    dentogingival junction
  3. epithelium that stands away from the tooth creating a gingival sulcus
    sulcular epithelium
  4. The sulcular epithelium in healthy gingiva is how many mm deep?
    .5 to 3mm
  5. What is the normal sulcular epithelium gingival fluid flow rate?
    1-2 microliters per tooth per hour
  6. deeper extension of suclular epithelium and lines the floor of the gingival sulcus
    junctional epithelium
  7. What is the tooth surface attachment of the junctional epithelium?
    • enamel
    • cementum
    • dentin
  8. true or false. junctional epithelium is thinner than sulcular epithelium
  9. junctional epithelium is ____-___cells thick at the coronal portion (floor of gingiva)
  10. junctional epithelium is 15-30 cells thick at the________portion (_____ __ _____ ________)
    • coronal
    • floor of gingival sulcus
  11. junctional epithelium is ___-___cells thick at the apical portion
  12. junctional epithelium is 3-4 cells thick at ________portion
  13. What are 2 clinical considerations with gingival tissue?
    • gingival recession
    • gingival hyperplasia
  14. What are 6 things that can cause gingival recession?
    • periodontal disease
    • tooth position
    • tooth brush abrasion
    • frenal attachments
    • abfraction
    • aging
  15. gingival hyperplasia affects__________ and __________
    • epithelium
    • lamina propria
  16. What are 3 drugs that can cause gingival hyperplasia?
    • seizure control drugs (phenytoin)
    • antibiotics
    • heart meds
  17. an increase output of certain fibroblasts occurs in what clinical consideration of gingival tissue?
    gingival hyperplasia
  18. The amount of overgrowth in gingival hyperplasia is related to_______ _______ combined with ______ ________
    • drug
    • dose
    • bacterial
    • biofilm
  19. true or false. gingival hyperplasia can be orthodontic related. overgrowth removal of gingival hyperplasia is possible
    both statements are true
  20. What are 4 clinical considerations with junctional epithelium?
    • permeable
    • sings of gingivitis
    • gingival fluid
    • exudate
  21. WBC's and biofilm microorganisms infiltrate junctional epithelium because what?
    the epithelium is permeable
  22. inflammation, epithelial ulceration, tissue thinning, and increased sulcular fluid in the junctional epithelium are signs of what?
  23. What supplies minerals for subgingival calculus, and then causes problems in the junctional epithelium?
    gingival fluid
  24. true or false. exudate is not currently measured in clinic
  25. sulcular fluid levels in junctional epithelium can be measured to indicate the_________ of _________
    • activity
    • disease
