Endo Terms

Question 1

Normal pulp (pulpal)

Answer 1

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

Question 2

Reversible pulpitis (pulpal)

Answer 2

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

Question 3

Symptomatic irreversible pulpitis (pulpal)

Answer 3

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.

Question 4

Asymptomatic irreversible pulpitis (pulpal)

Answer 4

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.

Question 5

Pulp necrosis (pulpal)

Answer 5

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

Question 6

Previously treated (pulpal)

Answer 6

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.

Question 7

Previously initiated therapy (pulpal)

Answer 7

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

Question 8

Normal apical tissues (apical)

Answer 8

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.

Question 9

Symptomatic apical periodontitis (apical)

Answer 9

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

Question 10

Asymptomatic apical periodontitis (apical)

Answer 10

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

Question 11

Acute apical abscess (apical)

Answer 11

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.

Question 12

Chronic apical abscess (apical)

Answer 12

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.

Question 13

Condensing osteitis (apical)

Answer 13

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

Question 14

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

Answer 14

Normal pulp (pulpal)

Question 15

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

Answer 15

Reversible pulpitis (pulpal)

Question 16

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.

Answer 16

Symptomatic irreversible pulpitis (pulpal)

Question 17

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.

Answer 17

Asymptomatic irreversible pulpitis (pulpal)

Question 18

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

Answer 18

Pulp necrosis (pulpal)

Question 19

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.

Answer 19

Previously treated (pulpal)

Question 20

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

Answer 20

Previously initiated therapy (pulpal)

Question 21

Answer 21

Normal apical tissues (apical)

Question 22

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

Answer 22

Symptomatic apical periodontitis (apical)

Question 23

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

Answer 23

Asymptomatic apical periodontitis (apical)

Question 24

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.

Answer 24

Acute apical abscess (apical)

Question 25

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.

Answer 25

Chronic apical abscess (apical)

Question 26

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