The lower incisors of a patient were injured four years ago. Now radiographs reveal a large radiolucent area associated with the apices of these teeth. Line of treatment is
1. Extract four incisors
2. Perform PA surgery
3. Endodontic treatment of only non-vital teeth
4. None of the above

Endodontics Answer: 3

The most common error seen during access cavity preparation of mandibular incisors is
1. Perforation of the lingual or labila walls
2. Gouging of pulpal contents
3. Tooth fracture
4. All of the above

Endodontics Answer: 1

The retention form in endodontic cavity is attained at
1. Junction of coronal preparation and radicular preparation
2. Coronal 2/3rd of radicular cavity
3. Apical 1/3rd radicular cavity
4. At the tip of the apex by apical matrix

Endodontics Answer: 3

Tooth discolouration most commonly result from
1. Hyperaemia of pulp
2. Pulp necrosis
3. Pulpal abscess
4. All of the above

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

Success of reimplanted avulses tooth depends on
1. Proper antibiotic coverage
2. Prevention of dehydration of PD ligament of avulsed tooth
3. Protection of socket
4. All of the above
