may present a fistula
tooth mobility
sensitivity to percussion
low grade fever
lymphadenopathy

Question 11

Answer 11

P. gingivalis
P. intermedia

proteinases

Question 12

Acute Periodontal abscess treatment

Answer 12

establish drainage
systemic or local delivery antibiotics
scale and root planing
surgery, if indicated

Question 13

Acute Gingival abscess clinical signs and symptoms

Answer 13

Localized
Painful
rapidly expanding
limited to marginal gingiva or gingival papillae
adjacent teeth may be painful to percussion
Etiology is generally impaction of a foreign body (i.e. popcorn hull, toothbrush bristle) and associated bacteria carried into tissue

Treatment for acute gingival abscess?

Answer 14

establish drainage
systemic or locally delivered antibiotics
scaling and root planing
surgery, if indicated

Answer 15

PAINLESS except during formation of periodontal abscess
Suprabony or intrabony pocket formation (>or= 4mm probing depth)
Loss of furcation bone (furcation invasion)
Gingival inflammation and recession
Loss of supporting alveolar bone
BOP

Question 16

Answer 16

Slight: 1-2mm of clinical attachment loss (CAL)
Moderate: 3-4mm CAL
Advanced: >5mm CAL

Question 17

Periodontal pocket is associated with what?

Answer 17

chronic and aggressive periodontitis

Question 18

How does NUP differ from ANUG?

Answer 18

NUP will have clinical attachment loss and alveolar bone loss

(all other characteristics are the same)

Question 19

Necrotizing Ulcerative Periodontitis (NUP) clinical symptoms

Answer 19

Answer 20

gram-neg. anaerobic enterics
—clostridium, klebseilla, enterococcus
candida albicans
epstein-barr virus
