Diagnoses

Question 1

What is ‘normal pulp’?

Answer 1

1. No spontaneous symptoms
2. Responds to pulp tests (mild symptoms, resolves within 2 seconds)
3. XR = no caries, resorption or mechanical exposure of pulp

Question 2

What is ‘reversible pulpitis’?

Answer 2

1. Stimulation (hot, cold, sweet) uncomfortable but reverses quickly
2. Caries, exposed dentine, recent dental tx, defective rests
3. Removal of irritant will resolve symptoms
4. Dentine hypersensitivty

Question 3

What is ‘symptomatic irreversible pulpitis’?

Answer 3

1. Spontaneous sharp pain
2. Prolonged pain after stimulus removed (>30s)
3. Postural pain
4. OTC analgesics typically ineffective
5. XR = NAD; no TTP (not yet reached PA tissues)

Question 4

What is ‘asymptomatic irreversible pulpitis’?

Answer 4

1. No symptoms

2. Trauma/ deep caries

Question 5

What is ‘necrosis’?

Answer 5

1. No symptoms
2. No response thermal/ electrical
3. TTP
4. XR = PDL widening to PAP

Question 6

What is ‘peri-radicular periodontitis’?

Answer 6

SYMPTOMATIC (ACUTE)

1. Very TTP
2. +/- sensibility tests
3. Widening PDL but no PAP

ASYMPTOMATIC (CHRONIC)

1. No symptoms
2. No response to tests
3. PAP
4. No TTP but ‘feels diff’

Question 7

What is ‘peri-radicular abscess’?

Answer 7

ACUTE

1. V painful (bite, TTP, palpate)
2. No response to tests
3. Mobility
4. XR = widening PDL to PAP
5. Swelling
6. Systemic w/ lymphadenopathy

CHRONIC

1. Generally no symptoms
2. No response to tests
3. XR = PAP
4. Tooth feels different
5. DRAINAGE THROUGH SINUS TRACT (difference with chronic periradicular periodontitis
