disorders of pulp

Question 1

functions of dental pulp

Answer 1

forms dentin throughout the tooth’s life
initiation
innervation
nutrition
formation
defense

Question 2

etiology of pulpal pathosis

Answer 2

bacterial (caries and periodontal)
trauma
restorative procedures

Question 3

changes in pulpal health

Answer 3

increase temp sensitivity
spontaneous pain
later percussion sensitivity

Question 4

diagnosis of pathosis

Answer 4

objective and subjective tests
clinical examination
thorough dental history

Question 5

cold test

Answer 5

apply cold substance

use adjacent teeth for baseline

Question 6

electric pulp test

Answer 6

lets go at first sign of sensation

adjacent teeth used for baseline

Question 7

normal pulp

Answer 7

normal responses
cold response is short and sharp
no percussion and palpation tenderness
normal radio graphic appearance

Question 8

reversible pulpitis

Answer 8

short sharp response to thermal stimulus
increase in cold sensitivity
sweet sensitivity
presence of large restorations/caries

Question 9

irreversible pulpitis

Answer 9

inflammation within the dental pulp
carious pulp exposure
large restoration 
trauma
hot/cold sensitivity (throbbing pain, lingering pain, spontaneous pain, differing from control teeth, percussion sensitivity)

Question 10

necrotic pulp

Answer 10

non-responsive to thermal
non-responsive to EPT
possible changes to periapical space

Question 11

periapical abscess

Answer 11

purulent exudate surround by connective tissue
severe pain due to inflammation
direct pulp inflammation or previous chronic inflammation

Question 12

dental or periapical granule a

Answer 12

chronically inflamed granulomatous tissue at the opening of the pulp canal
may be asymptomatic
round of ovoid translucent lesion
endo or extraction

Question 13

radicular cyst (periapical cyst)

Answer 13

developers from periapical granulomas
lateral or apex of tooth
endo, eco, curettage

Question 14

tooth resorption

Answer 14

normal as tooth exfoliates
external (begins outside of tooth, affects tooth roots, irreversible, can be arrested)
internal (inflam. response, endo treatment)
causes (inflammation, pressure from tooth movement, eruption, slow or rapid growth, impactions)

Question 15

Condensing osteitis

Answer 15

change in bone at apex due to low-grade inflammation
radiopaque area extending below roots
usually mand 1st molar
carious or heavily restored teeth

Question 16

alveolar osteitis

Answer 16

dry socket
blood clot breaks down, lost before healing occurs
extreme pain
socket appears empty and bone is exposed
pain, bad taste, odor
