Flashcards in Lecture 9 - Pulpal, Periapical and Odontogenic Infections Deck (34):
1

What are the damages of inflammation to pulp?

increases intrapulpal pressure
compromises blood flow
tissue damage
pulpal necrosis?

2

T/F
the pulp is an organ enclosed by hard tissue
the roots of a tooth are enclosed by hard tissue

T
F - bone

3

what is the most common cause of pulpal inflammation and necrosis?

bacterial infection

4

What are other causes of pulpal inflammation and necrosis?

direct pulpal exposure
bacterial penetration through dentinal tubules from caries
direct access due to traumatic fracture
travel from bloodstream (anachoresis)

5

What is necessary for pulpal and periapical disease to occur?

bacteria

6

most bacteria cultured from necrotic pulps are _________, usually gram - _________ bacilli

anaerobic

7

which species are associated with periapical abscesses?

prevotella
porphyromonas

8

which species are responsible for foul odor of necrotic pulps?

prevotella
porphyromonas

9

Give an example of a mixed bacterial infection

endodontic infection

10

Which type of bacteria are found coronally?

saccharolytic bacteria (strep, lactobacilli)

11

which type of bacteria are found apically?

proteolytic bacteria (porphyromonas, prevotella, fusobacterium)

12

Describe the pain of pulpitis.

severe, sharp, throbbing pain

13

for periapical lesions, where are bacteria most numerous?

root canal

14

T/F
most periapical lesions are granulomas and dominated by macrophages
periapical lesions are asymptomatic

T
T

15

describe the pain for acute dentoalveolar (periapical) abscess

aching, throbbing pain

16

What can cause relief for someone with acute dentoalveolar (periapical) abscess?

draining pus

17

The purulent bacterial infection that is dentoalveolar (periapical) abscess is confined to bone at:

the apex

18

Give an example of palliative treatment.

Give an example of definitive treatment.

analgesics, local anesthetics, NOT ANTIBIOTICS - they cannot reach source of problem
extraction of tooth, root canal treatment

19

persistent periapical infections after root canal treatment

persistent apical lesions

20

surgical therapy used to clean apex of bacteria and necrotic tissue

endodontic microsurgery = apicoectomy

21

the apex during treatment of persistent apical lesions is sealed with a biocompatible agent like:

mineral trioxide aggregate (MTA)

22

an infections is said to be odontogenic when:

a dental infection spreads to surrounding tissues

23

T/F
lower facial cellulitis is never dental
antibiotics should be used to manage cellulitis

F - almost always dental
T

24

A cellulitis abscess requires which type of treatment?

drainage through surgery

25

Describe the ratio of microbiology of cellulitis

2-3 anaerobes: 1 aerobes

26

what are the two antibiotics of choice for cellulitis?

clindamycin
penicillin

27

name 3 bone infections

alveolar osteitis (dry socket)
osteomyelitis of jaw
antiresorptive agent-induced osteronecrosis of jaw

28

Describe alveolar osteitis and the feeling of it.

swelling, redness, exposed bone
painful, throbbin, aching

29

Symptoms of osteomyelitis

swelling
pain
erythema

30

is osteomyelitis radiolucent or radiopaque?

radiolucent

31

which kind of patients are susceptible to antiresorptive agent-induced osteonecrosis of jaw?

patients who have taken antiresorptive agents

32

Name the 3 antiresorptive agents

bisphosphonates
denosumab
cathepsin K inhibitors

33

what do antiresorptive agents do?

inhibit osteoclasts and bone remodeling

34

T/F
avoid dental extractions in immunocompromised patients that have used bisphosphonates
