Pathogenesis of Periodontal Disease 2

Question 1

2 causes of pathologic migration of teeth

Answer 1

A. Tongue-thrusting habits
B. Loss of posterior teeth

Question 2

This is a feature of acute inflammation of the periodontal ligament

Answer 2

Sensitivity to percussion

Question 3

Plaque and calculus is most common in?

Answer 3

A. Lingual of mandibular incisors
B. Buccal of maxillary molars

Question 4

2 basic types of gingival tissue response

Answer 4

A. Edematous
B. Fibrotic

Question 5

This gingival tissue response is smooth, glossy, soft gingiva and is usually seen in acute inflammation

Answer 5

Edematous

Question 6

This gingival tissue response is firm, stippled, opaque, thicker, more rounded margins and is seen in chronic inflammation

Answer 6

Fibrotic

Question 7

This is the gold standard for periodontal assessment

Answer 7

Pocket probing

Question 8

2 types of pocket depths

Answer 8

A. Biologic depth
B. Probing depth

Question 9

This type of pocket depth is from gingival margin to the junctional epithelium

Answer 9

Biologic depth

Question 10

This type of pocket depth is where the probe can enter/ reach only

Answer 10

Probing depth

Question 11

This is the distance between the base of the pocket and a fixed point, usually CEJ

Answer 11

Level of attachment

Question 12

This is the distance between the base of the pocket to the gingival margin; gingival overgrowth produces higher readings

Answer 12

Pocket depth

Question 13

2 types of periodontal pockets

Answer 13

A. Pseudo-pocket
B. Real pocket

Question 14

This is the fake pocket; present when there is gingival growth; no bone loss or clinical attachment loss

Answer 14

Pseudo-pocket

Question 15

This type of pocket has loss of alveolar bone and loss of clinical attachment

Answer 15

Real pocket

Question 16

4 uses of periodontal probes

Answer 16

A. Used to measure pocket depth
B. Quantification of bacterial plaque and gingival inflammation
C. Determination of mucogingival relationship
D. Measurement of gingival recession

Question 17

Images taken from the radiograph can be manipulated on the computer screen to adjust its density, contrast, and magnification

Answer 17

Digital radiography

Question 18

4 importance of radiography in periodontics

Answer 18

A. Diagnosis periodontal disease
B. Estimation of severity
C. Determination of prognosis
D. Evaluation of treatment outcome

Question 19

This is a thin radiopaque line adjacent to the periodontal ligament

Answer 19

Lamina dura

Question 20

In this bone defect, its radiographic appearance is a break or fuzziness at the crest of the interdental alveolar bone

Answer 20

Early bony changes

Question 21

In this bone defect, its radiographic appearance is a presence of finger-like radiolucent projection into the interdental alveolar bone

Answer 21

Early bone changes

Question 22

In this bone defect, its radiographic appearance can be measured from a plane that is parallel to a tooth-to-tooth line drawn from the CEJ’s of adjacent teeth

Answer 22

Horizontal bone loss

Question 23

In this bone defect, its radiographic appearance is seen as more bone loss on the interproximal aspect of one tooth than on the adjacent tooth

Answer 23

Vertical bone loss

Question 24

In this bone defect, its radiographic appearance are radiolucent areas due to bone loss

Answer 24

Bone defects

Question 25

In this bone defect, its radiographic appearance is a loss of bone in furcation area and may be detectable as triangular radiolucency especially on the mandibular molars

Answer 25

Furcation involvement
