  9. what does periodontal mean?
    around the tooth
  10. a group of diseases that affects the tissues around the teeth:

    periodontal disease

    • teeth
  16. a clinical exam must be performed by who?
    the dentist and dental hygienist

    • posttreatment
    • follow-up
  21. why might the furcation area not be seen on a radiograph?
    because of the superimposition of the buccal and lingual bone
  22. T/F a radiograph allows the dental professional to view the amount of bone lost rather that the amount remaining
    false! view the amount remaining rather than the amount lost

    bone loss
  25. the pattern of bone loss can be described as ________ or _________
    vertical or horizontal
  26. with ________ bone loss, the bone loss occurs in a plane parallel to the CEJ's of adjacent teeth
  27. with ________ bone loss (angular bone loss) the bone loss does not occur in a plane parallel to the CEJs of adjacent teeth
  28. distribution of bone loss can be: (2)
    • generalized
    • localized
  29. which bone loss occurs in isolated areas with less than 30% of sites involved?
    localized bone loss
  30. which bone loss occurs evenly throughout the dental arches, with more than 30% of the sites involved?
  31. the severity of bone loss is described as: (3)
    • slight
    • moderate
    • severe
  32. the measurement of the distance in millimeters from the CEJ to the base of the sulcus or periodontal pocket is:
    CAL clinical attachment loss
  33. bone loss: 1-2mm:
  34. bone loss: 3 to 4 mm
  35. bone loss: 5mm or greater
  36. ADA Case Type I:
  37. ADA Case Type II
    mild or slight periodontitis
  38. ADA Case Type III
    moderate periodontitis
  39. ADA Case Type IV
    advanced or severe periodontitis
  40. is there radiographic change seen on a radiograph in the bone for a type I disease?
  41. what case type are mild crestal changes?
    case type II mild or slight periodontitis
  42. the lamina dura becomes unclear and fuzzy and no longer appears to be a continuous radiopaque line. Horizontal bone loss is seen more often in this type of disease
    type II mild or slight periodontitis
  43. 3-4mm apical to CEJ, clinically BOP may occur, pocket depths from attachment loss may be present and areas of recession may be seen in this type:
    type II mild or slight periodontitis
  44. which type might horizontal or vertical bone loss be present, localized or generalized?
    type III moderate periodontitis
  45. alveolar bone level 4-6 mm apical to the CEJs of adjacent teeth. furcation involvement or the extension of perio between the roots of the multirooted teeth may be seen with this disease type:
    type III moderate periodontitis
  46. recession, furcation involvement areas, and slight mobility = type:
    type III moderate periodontitis
  47. the pattern of bone loss may be horizontal or vertical and the alveolar bone level is 6mm or greater from the CEJ.
    type IV advanced or severe periodontitis
  48. the effect of certain _________, tobacco use, and someone with ________ are predisposing risk factors for perio
    • medications
    • diabetes
