Q

What is the brief AAE definition of a “normal pulp”?

A

Diagnostic category where the pulp is symptom-free and normally responsive to pulp testing.
Mild/ transient response to thermal cold testing
Must test tooth against others in the mouth to confirm.

Q

What is the AAE definition of asymptomatic irreversible pulpitis?

A

Vital inflamed pulp is incapable of healing and that RCT is indicated.
No clinical symptoms.
Usually respond normally to thermal testing.

Q

What is the AAE pulpal definition of previously treated tooth?

A

When the tooth has been endodontically treated and the canals are obturated with various filling materials other than intracanal medicaments.

Typically does not respond to thermal/ electric pulp testing.

Q

What is the AAE pulpal definition of previously initiated therapy?

A

Tooth has been previously treated by partial endodontic therapy such as pulpotomy or pulpectomy.

Tooth may or may not respond to pulp testing depending on level of therapy.

Q

What is the AAE pulpal definition of reversible pulpitis?

A

Pulpal inflammation should resolve and the pulp return to normal following appropriate management of the aetiology.

Pain symptoms include:
Response to cold/ sweet stimulus
Goes away within a couple seconds following removal of stimulus

Q

What are the typical aetiologies of reversible pulpitis?

A

Exposed dentine - dentinal hypersensitivity
Deep caries
Deep restorations

17
Q

What is the AAE apical definition of normal apical tissues?

A

Not sensitive/ TTP or palpation testing
Radiographically - lamina dura surrounding the root is intact and PDL space is uniform

18
Q

What is the AAE apical definition of symptomatic apical periodontitis and what symtpoms does this produce?

A

Represents inflammation usually of the apical periodontium
Produces clinical symptoms:
Pain to biting
and/ or
TTP
pain on palpation

19
Q

What does severe pain to percussion indicate?

A

Highly indicative of a degenerating pulp and root canal treatment is needed

20
Q

What is the AAE apical definition of asymptomatic apical periodontitis and how does this present radiographically?

A

Inflammation and destruction of the apical periodontium that is of pulpal origin.
Appears as an apical radiolucency and does not present clinical symptoms (no pain on percussion or palpation).

21
Q

What is the AAE definition of a CHRONIC apical abscess?

A

An inflammatory reaction to pulpal infection and necrosis characterized by gradual onset, little or no discomfort and an intermittent discharge of pus through an associated sinus tract.

22
Q

How can you identify the source of a draining sinus tract?

A

A GP cone is carefully places through the opening until it stops and a radiograph is taken

23
Q

What is the AAE definition of an ACUTE apical abscess?

A

An inflammatory reaction to pulpal infection and necrosis characterized by - rapid onset, spontaneous pain
- extreme tenderness of the tooth to pressure
- pus formation
- swelling of associated tissues.
There may be no radiographic signs of destruction and the patient often experiences malaise, fever and lymphadenopathy.

24
Q

What is the AAE definition of condensing osteitis?

A

A diffuse radiopaque lesion representing a localized bony reaction to a low-grade inflammatory stimulus usually seen at the apex of the tooth.
