Q

Difference between reversible or irreversible pulpitis (2)

A

Depends on clinical symptoms
Reversible pulpitis - pain to cold, lasts a short time; hydrodynamic expression (microleakage)
Irreversible pulpitis - spontaneous pain, negative to cold (pain to hot), increase in plural blood flow

Pulpotomy, RCT/extraction (immature teeth)

18
Q

Definition of pulpotomy

A

19
Q

A

Full removal of pulp

20
Q

Features of normal periodical tissue (2)

A

Not sensitive to percussion/palpation

Normal radiograph

21
Q

Features of symptomatic periodical periodontitis (3)

A

Inflammation of apical periodontium
Pain caused by biting, percussion, palpation
Periodical radiolucency radiographically

22
Q

Features of asymptomatic periodical periodontitis (3)

A

Inflammation and destruction of apical periodontium (of plural origin)
Periodical radiolucency radiographically
No present clinical symptoms

23
Q

Features of acute apical abscess (4)

A

Inflammatory reaction to plural infection and necrosis
Rapid inset, results in spontaneous pain
Extremely tender to pressure, results in swelling and pus formation
Malaise, fever, lymphadenopathy

24
Q

Features of chronic apical abscess (4)

A

Inflammatory reaction to plural infection and necrosis
Gradual onset, little/no discomfort
Intermittently discharge pus through sinus tract
Results in radiographic periodical/periradicular radiolucency

25
Q

Features of condensing osteitis (3)

A

Localised bony reaction to a low-grade inflammatory stimulus
Seen at apex of tooth
Diffuse radiopaque lesion

26
Q

Signs that a tooth may be non-vital (5)

A 
Discolouration (yellow/grey/pink)
Sinus
Gross caries
Large restorations
Radiographic evidence (periapical/periradicular radiolucency)
27
Q

Primary function of a sensibility test

A

To differentiate vital from non-vital pulp

28
Q

Types of sensibility test (3)

A

EPT
Thermal tests (hot/cold)
Test drilling

29
Q

Types of thermal test (2)

A

Cold test - ethyl chloride

Hot test - hot gutta percha stick

30
Q

Associated clinical factors when considering pulp care and treatment (4)

A

Carious pulp exposure
Age
Periodontal disease
Previous pulpal insult/trauma

31
Q

Previous pulpal insult includes (4)

A

Caries
Caries removal
Restorative procedures
Involves tubular occlusion

32
Q

Function of CaOH

A

Encourage tertiary dentine formation. It has bactericidal/bacteriostatic action, but is cytotoxic

33
Q

Treatment of plural damage (4)

A

Placing an indirect pulp cap/stepwise excavation
Direct pulp cap
Partial plural removal (pulpotomy)
Full plural removal (pulpectomy and then RCT)
