Question 3

What is the prognosis for the following:

Answer 14

A. actimomycetemcomitans

Question 15

Answer 15

yellow & green

Question 16

What bacterial complexes are specific to periodontitis?

Answer 16

orange & red

Question 17

Bacteria associated with pregnancy”

Answer 17

P. intermedia

Question 18

Difference between scaling and root planing:

Answer 18

Scaling- removing the calculus
Root planing- smoothing the surface

Question 19

Bacteria that causes abscess in the periodontium:

Answer 19

P. gingivalis

Question 20

Inflammation, no destruction of PDL or bone, no apical migration of epithelial attachment:

Answer 20

Gingivitis

Question 21

Inflammation, destruction of bone, apical migration of epithelial attachment:

Answer 21

Periodontitis

Question 22

Stages of gingivitis:

Answer 22

intial
early
established
advanced

Question 23

How to work through a case:

Answer 23

1. Probing depths (over 4mm would consider scaling in the presence of gingivitis if BOP and plaque score is high)
2. BOP score (over 30%= generalized)
3. Plaque index: high = scaling in presence
4. Check radiographic bone loss
5. Check patient’s medical history for modifying factors

List the tooth loss due to perio disease for each stage:

Stage 1:
Stage 2:
Stage 3:
Stage 4:

Answer 24

Stage 1: No tooth loss
Stage 2: No tooth loss
Stage 3: </= 4
Stage 4: >/= 5
