Old Exam Questions: Flashcards
Moderate chronic periodontitis would have how much attachment loss?
3-4 mm moderate
T/F: Aggressive periodontitis can be classified as mild, moderate, or severe
False- only localized/generalized
All of the following are part of the periodontium except:
a- gingiva
b- PDL
c- cementum
d- alveolar mucosa
d- alveolar mucosa
(gingiva, PDL, cementum & alveolar process = periodontium)
Determine attached gingiva when given keratinized gingiva and probing depth:
attached = keratinized - probing depth
T/F: Interdental gingiva (col) is non-keratinized
True
Non-keratinized = sulcular epithelium interdental gingiva, & JE
Keratinized= free gingiva, attached gingiva & oral epithelium
Which of the following is keratinized gingiva?
a- oral epithelium
b- sulcular epithelium
c- junctional epithelium
a- oral epithelium
Which of the following structures make up the tissue from the CEJ to the alveolar bone?
a- junctional epithelium
b- connective tissue
c- sulcular epithelium
a- junctional epithelium
b- connective tissue
What makes up sharpeys fibers?
a- oxytalin
b- transseptal
c- gingival
d- collagen
d- collagen
The shape of the alveolar process is dependent on all of the following EXCEPT:
a- interdental distance
b- tooth contours
c- crown to root ratio
d- root contours
c- crown to root ratio
The distance from the CEJ to alveolar bone in a healthy adult is:
a- 1.0 mm
b- 1.5 mm
c- 2.0 mm
c- 2.0 mm
T/F: Fenestration is the lack of bone on the facial or lingual of the tooth resembling a “window”
True
Dehiscence = lack of bond on facial or lingual of tooth with interproximal bone
Approximately how many dentate patients have periodontitis in the use?
50%
The inorganic components of plaque mainly are:
calcium and phosphorus (NOT POTASSIUM)
The organic components of plaque are mainly:

- glycoproteins
- lipids
The biological width is made up of:
junctional epithelium and connective tissue
What is the CD4 count in HIV patients?
200
What bacteria fits Spcransky’s Criteria?
AA and Pg

b- unattached
c- epithelial
d- connective tissue
d- connective tissue
Plaque accumulates ____ from the patients diet
polysaccharides
Successful colonization is dependent on all of the following except:
a- overcoming host defenses
b- successful competition
c- number of bacterial colonies
d- nutritional relationships
c- number of bacterial colonies
AA is predominant in:
localized aggressive periodontitis
Pg is predominant in:
chronic periodontitis
Established lesion has epithelial changes that include:
a- PGE
b- IL-4
c- complement activation
d- tissue damage
