1
Q

Normal Pulp:

A

A clinical diagnostic category in which the pulp is symptom-free and normally responsive to pulp testing.

2
Q

Reversible Pulpitis:

A

A clinical diagnosis based upon subjective and objective findings indicating that the inflammation should resolve and the pulp return to normal.

3
Q

Symptomatic Irreversible Pulpitis:

A

A clinical diagnosis based on subjective and objective findings indicating that the vital inflamed pulp is incapable of healing.
Additional descriptors: Lingering thermal pain, spontaneous pain, referred pain.

4
Q

Asymptomatic Irreversible Pulpitis:

A

A clinical diagnosis based on subjective and objective findings indicating that the vital inflamed pulp is incapable of healing.
Additional descriptors: No clinical symptoms but inflammation produced by caries, caries excavation, trauma, etc.

5
Q

Pulp Necrosis:

A

A clinical diagnostic category indicating death of the dental pulp. The pulp is usually nonresponsive to pulp testing.

6
Q

Previously Treated:

A

A clinical diagnostic category indicating that the tooth has been endodontically treated and the canals are obturated with various filling materials other than intracanal medicaments.

7
Q

Previously Initiated Therapy:

A

A clinical diagnostic category indicating that the tooth has been previously treated by partial endodontic therapy (e.g., pulpotomy, pulpectomy).

8
Q

Normal Apical Tissues:

A

Teeth with normal periradicular tissues that are not sensitive to percussion or palpation testing. The lamina dura surrounding the root is intact and the periodontal ligament space is uniform.

9
Q

Symptomatic Apical Periodontitis:

A

Inflammation, usually of the apical periodontium, producing clinical symptoms including a painful response to biting and/or percussion or palpation. It may or may not be associated with an apical radiolucent area.

10
Q

Asymptomatic Apical Periodontitis:

A

Inflammation and destruction of apical periodontium that is of pulpal origin, appears as an apical radiolucent area, and does not produce clinical symptoms.

11
Q

Acute Apical Abscess:

A

An inflammatory reaction to pulpal infection and necrosis characterized by rapid onset, spontaneous pain, tenderness of the tooth to pressure, pus formation and swelling of associated tissues.

12
Q

Chronic Apical Abscess:

A

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

13
Q

Condensing Osteitis:

A

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