1ppm

Question 8

Guiding Principles for Caries Management

● Five Guiding Principles

Answer 8

○	Assess caries risk status 
○	Diagnose the disease early
○	Treat the disease by
      ■	Remineralizing tooth surface
      ■	Controlling the infection 
○	Avoid or delay operative intervention
○	Restore “active” disease only

Question 9

○ Inadequate saliva flow

Answer 9

less that 0.5 mL/ min

Question 10

● Normal Pulp

Answer 10

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

Question 11

● Reversible Pulpitis

Answer 11

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

Question 12

● Symptomatic Irreversible Pulpitis

Answer 12

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

Question 13

● Asymptomatic Irreversible Pulpitis

Answer 13

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

Question 14

● Pulp Necrosis

Answer 14

○ A clinical diagnostic category indicating death of the dental pulp
○ Pulp is nonresponsive to pulp testing

Question 15

● Previously Treated

Answer 15

○ 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 16

● Previously Initiated Therapy

Answer 16

○ Clinical diagnostic category indicating that the tooth has been previously treated by partial endodontic therapy
○ Pulpotomy, pulpectomy, etc.

Question 17

● Normal Apical Tissues

Answer 17

○ 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 18

● Symptomatic Apical Periodontitis

Answer 18

○ Inflammation of apical periodontium producing clinical symptoms including:
■ Painful response to biting, percussion, or palpation
○ May or may not be associated with apical radiolucent area

Question 19

● Asymptomatic Apical Periodontitis

Answer 19

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

Question 20

● Acute Apical Abscess

Answer 20

○ Inflammatory reaction to pulpal infection and necrosis characterized by rapid onset, spontaneous pain, tenderness of tooth to pressure, pus formation, and swelling of associated tissues

Question 21

● Chronic Apical Abscess

Answer 21

○ 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 22

● Condensing Osteitis

Answer 22

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

Question 23

● 3 different terms used for the primordial root:

Answer 23

○ Cervical loop
○ Hertwig’s epithelial root sheath
○ Epithelial diaphragm
