The flashcards below were created by user jackiedh on FreezingBlue Flashcards. What would you like to do?

  1. which lesion is the inflammatory response to biofilm?
    initial lesion
  2. which lesion is the increased inflammatory response?
    early lesion
  3. which lesion is the progression from the early lesion?
    established lesion
  4. which lesion is the extension of inflammation?
    advanced lesion
  5. which inflammation occurs within 2-4 days from irritation of bacterial accumulation?
    initial lesion
  6. which lesion does dental biofilm become older and thicker in 7-14 days?
    early lesion
  7. which lesion is this?
    infiltration of wbc's increase flow of gingival sulcus fluid, breakdown of collagen, and fluid filled space in connective tissue
    no clinical evidence of change
    slight marginal redness with enlargement from fluid collection as infection develops?
    initial lesion
  8. which lesion is this?
    infiltration of fluid, lymphocytes, neutrophils
    epithelium proliferates
    epithelial extension and rete ridges form
    early gingivitis; reversible when biofilm is controlled
    JE migrates
    early lesion
  9. which lesion is this?
    fluid and leukocyte migration increases
    formation of pocket epithelium
    proliferation of JE and SE wall out inflammation?
    established lesion
  10. which lesion is this?
    pocket epithelium is more permeable
    early pocket formation
    collagen destruction continues
    some lesions may remain stable for a long time
    marginal redness, BOP, spongy marginal gingiva
    established lesion
  11. which lesion is 5mm or more?
    advanced lesion
  12. which lesion is this?
    supragingival biofilm is the source for subgingival biofilm
    biofilm microorganisms provide irritants
    alveolar bone destruction
    inflammation enters bone through small vessel channels in alveolar crest
    inflammation spreads through bone marrow and out PDL
    advanced lesion
  13. when epithelium migrates along root surface
    coronal JE becomes detached
    exposed cementum where sharpeys fibers were attached
    diseased cementum contains a thin layer of endotoxins from bacterial breakdown
    what is this?
    progression of destruction of connective tissue (in the advanced lesion)
  14. what are characteristics of the advanced lesion? 8
    • pocket formation
    • mobility
    • bone loss
    • furcation
    • plasma cells predominate
    • je continues to migrate
    • lesion extends through CT
    • activity and inactivity periods
  15. what is case type I?
    gingival disease
  16. what is case type II?
    early periodontitis
  17. what is case type III?
    moderate periodontitis
  18. what is case type IV?
    advanced periodontitis
  19. which case type is:
    the inflammation of the gingiva
    changes in color
    gingival form, position, surface appearane
    presence of bleeding and or exudate?
    case type I gingival disease
  20. which case type is 1-3mm?
    gingival disease type I
  21. which case type has progression of the gingival inflammation into the deeper perio structures and alveolar bone crest with slight bone loss?
    case type II early perio
  22. which case type is there usually a slight loss of CT attachment and alveolar bone?
    case type II early perio
  23. which case type has a lot or no calc, 1-5mm?
    case type II early perio
  24. which case type has increased destruction of the perio structures and noticeable loss of bone support, esp on radiographs?
    case type III moderate perio
  25. which case type has increase in tooth mobility, may or may not have furcation involvement with multi-rooted teeth?
    case type III moderate perio
  26. which case type is 4-6mm?
    case type III mod perio
  27. which case type has further progression of perio with major loss of alveolar bone support?
    case type IV advanced perio
  28. which case type is usually accompanied by increased mobility, and furcation involvement?
    case type IV advanced perio
  29. which case type is >7mm?
    case type IV advanced perio
