06 Diagnosis

Question 1

Parulis

Answer 1

intraoral dental sinus

Question 2

Stoma

Answer 2

associated with sinus tract (the opening)

Question 3

primary endo radiograph is:

Answer 3

the periapical radiograph

Question 4

how much mobility would indicate that the tooth has a poor prognosis for endo treatment?

Answer 4

if the tooth is depressible or moves 2-3 mm

Question 5

what are the different periapical tests?

Answer 5

• percussion
• palpation
• bite

Question 6

what are the sensibility (vitality) tests?

Answer 6

• cold
• ept to confirm
• heat (if indicated by symptoms)

Question 7

during palpation, a painful response indicates:

Answer 7

periapical inflammation

Question 8

during percussion, a painful response indicates:

Answer 8

periapical inflammation

Question 9

analysis of percussion and palpation readings (+’s mean what?)

Answer 9

N=no pain
+=Slight pain
++=Moderate pain
+++= severe pain

Question 10

sensitivity (esp rebound) when biting can indicate:

Answer 10

a cracked tooth or cusp

Question 11

cold testing is more effective on anterior or posterior teeth?

Answer 11

anterior

Question 12

what is an abnormal response to a cold test?

Answer 12

Prolonged severe (at least compared to other adjacent teeth)

Question 13

false negatives on cold tests could be the result of what?

Answer 13

• receded or constricted pulp or

- transference of stimulus to adjacent teeth or soft tissue

Question 14

what cotton pellet for cold testing

Answer 14

large #2 cotton (especially for testing thru full coverage crowns

Question 15

what else can be used for cold testing?

Answer 15

Endo Ice, just as effective as CO2 snow. may even have a quicker response

Question 16

analysis of cold readings:

Answer 16

0=No pain (not normal, necrotic)
+= slight pain, immediately reversed
++= moderate pain immediately reversed
+++= severe pain that does not go away when stimulus is removed

Question 17

EPT Method:

Answer 17

• teeth isolation and drying with air syring
• toothpaste on electrode as conductor
• patient touches the metal handle (complete circuit)
• electrode placed on buccal or occlusal surface

Question 18

can EPT be performed on full coverage crowns?

Answer 18

NO

Question 19

method for heat testing

Answer 19

• hot water
• dry rubber prophy cup (frictional)
• heated gutta percha
• **rubber dam isolation, not a routine test, only when major symptom is heat sensitivity

Question 20

transillumination

Answer 20

identify fractures

Question 21

what are the possible pulpal diagnosis?

Answer 21

• normal pulp
• reversible pulpitis
• symptomatic irreversible pulpitis
• asymptomatic irreversible pulpitis
• necrotic pulp
• previously treated
• previously initiated

Question 22

what are the possible periapical diagnosis?

Answer 22

• normal
• symptomatic apical periodontitis
• asymptomatic apical periodontitis
• acute apical abscess
• chronic apical abscess

Question 23

cold test +++

Answer 23

Symptomatic irreversible pulpitis

Question 24

if there is swelling/pus

Answer 24

acute or chronic apical abscess

-positive to percussion and palpation

Question 25

chronic apical abscess

Answer 25

gradual onset, little or no discomfort, and intermittent discharge of pus through an associated SINUS TRACT

• percussion negative
• may be palpation positive if sinus tract is palpated
