2. Use copious amounts of irrigating solutions
3. Easy to control while operating
4. All of the above

Endodontics Answer: 2

RCT treated with well-filled post and core, has a periapical radiolucency
1. Apicoectomy and retrograde filling with silver
2. Periapical curettage and apicoectomy
3. Retreat and filling with gutta-percha
4. None of the above

Endodontics Answer: 1

"Tug back" during obturation refers to
1. Consistency of master cone
2. Apical seat fit of master cone
3. Size of the master cone
4. Length of the master cone

Endodontics Answer: 2

Which of the following is true of vertical and lateral condensation
1. Lateral condensation results in better seal
2. Vertical condensation results in better seal
3. Sealibility with either techniques depends on the shape of prepared canal
4. Both are recommended for filling lateral canals

Endodontics Answer: 3

An endodontist failed to obturate an accessory canal while obturating main canal. Immediate treatment
1) No treatment, observe periodically
2) Surgical expose and retrofill
3) Retrieve and reobturate
4) Apicetomy and retrofill

Endodontics Answer: 1

All of the following are true about gutta-percha cone except
1. Gutta-percha is composed of 60-85 % gutta-percha and 20 % zinc oxide
2. Used in lateral condensation method
3. When heated exists in a & b form
4. All of the above are true
