Q

How does a necrotic pulp respond to a cold test?

A

No response

25
Q

What could cause a false positive on a cold test?

A

Transference of stimulus to adjacent teeth or soft tissue

26
Q

What could cause a false negative on a cold test

A

Receded on constricted pulp

27
Q

Can you cold test through full coverage crowns?

A

Yes

28
Q

What kind of cotton pellet it used for cold testing

A

Large #2

29
Q

What is the VCU response grading to cold testing?

A 
0 = No Pain
\+ = Slight and immediate reversal
\++ = Moderate and immediate reversal
\+++ = Severe that does not go away immediately
30
Q

Does a 0 on a cold test always mean a dead pulp?

A

No

31
Q

Why does the EPT always restart at zero after breaking contact

A

To reduce chances of giving patient a shock

32
Q

Is EPT more important than cold testing?

A

No, it is secondary to cold test

33
Q

Can you perform an ept on crowns?

A

Not on full coverage Metal or PFM

34
Q

What does an 80/80 reading on the EPT indicate?

A

No response to electrical stimulation

35
Q

What is transillumination good at identifying?

A

Longitudinal cracks

36
Q

What are the 2 diagnoses that must be made for an official endo diagnosis

A

Pulpal AND Periapical

37
Q

What is the pulp diagnosis when the pulp is symptom free and normally responsive to vitality testing?

A

Normal pulp

38
Q

What are the diagnostic findings for a Normal pulp diagnosis

A

Cold response of +

Or no cold response with receded or sclerotic pulp (recorded as 0)

39
Q

What is the pulp diagnosis based upon subjective and objective findings indicating that the inflammation should resolve and the pulp return to normal

A

Reversible pulpitis

40
Q

What are the diagnostic findings for reversible pulpitis

A

Cold response of ++

No root canal needed

41
Q

What pulpal diagnosis is defined as findings that indicate the vital inflamed pulp is incapable of healing

A

irreversible pulpitis

42
Q

What are the two additional descriptors that can be used to describe the pulp diagnosis

A

Symptomatic and Asymptomatic

43
Q

What is the clinical diagnosis that indicates the death of the pulp

A

Pulp necrosis

44
Q

What are the diagnostic findings for Pulp necrosis

A

0 for Cold Test

80/80 for EPT

45
Q

What does Previously Treated mean

A

Tooth has had endo tx and the canals are obturated with filling material

46
Q

What are the diagnostic findings for previously treated

A

Will respond to cold and ept the same way necrotic pulp do….unless there is still vital pulp tissue in the tooth

47
Q

What is Previously Initiated Therapy

A

RCT started but not finished yet

48
Q

What is the PA diagnosis for a tooth with normal periradicular tissues with an intact lamina dura and uniform PDL space

A

Normal apical tissues

49
Q

What is the PA diagnosis for inflammation of the apical periodontium that produced clinical symptoms like painful response to biting and percussion. It may or MAY NOT be associated with an apical radiolucency

A

Symptomatic apical periodontitis

50
Q

How could you describe the diagnosis “Asymptomatic apical periodontitis”

A

Inflammation of apical periodontium that is of pulpal origin. It appears as an apical RL with no clinical symptoms

51
Q

What is the worst symptomatic diagnosis for perio

A

Acute apical abscess

52
Q

What is the diagnosis for a patient that has a gradual onset with little or no discomfort along with intermittent discharge of pus via sinus tract

A

Chronic apical abscess

53
Q

What pulp diagnosis would you give a tooth that has cold test score of ++?

A

Reversible pulpitis

54
Q

What pulp diagnosis would you give a tooth with a cold test score of +++?

A

Irreversible pulpitis

55
Q

What would the pulp diagnosis be for a cold test of 0 and an 80/80 ept?

A

Necrotic pulp

56
Q

What is the PA ddx for a tooth that scores:

N for percussion
N for palpation

A

Normal apical tissues

57
Q

What perio ddx would you give to a tooth with pain response to biting that may or may not have a response to palpation?

A

Symptomatic apical periodontitis

58
Q

What is the perio ddx for a tooth with an apical RL and:

N for percussion
N for palpation

A

Asymptomatic apical periodontitis

59
Q

What is the expected response to percussion and palpation testing for a chronic apical abscess?

A

Percussion negative

Palpation might be positive if sinus tract is palpated
