1) Peeso reamer
2) Gates-Glidden dril
3) K-flex file
4) Barbed broach

Endodontics Answer: 2

Instrumentation short of apical foramen results in
1. Forcing debris into PA area
2. Shelfing (or) ledging of canals
3. Enlarging of apical formamen
4. All of the above

Endodontics Answer: 2

In endodontic practice, periapical radiographs are very useful in assessing the
1. Length of the root canal
2. Presence of infection in the pulp
3. Vitality of the pulp
4. All of the above

Endodontics Answer: 1

Percussion test is mainly done
1) To test integrity of pulp tissues
2) To test the integrity of periodontal lingament
3) To test the vitality of the pulp tissues
4) To test the presence of chronic abscess

Endodontics Answer: 2

Carbamide solution used for bleaching degrades into
1) 0.3 % sodium perborate
2) 30 % hydrogen peroxide
3) 3 % hydrogen peroxide
4) 30 % sodium perborate

Endodontics Answer: 3

8-year-old child had fractured his maxillary central incisor 10 month ago. The pulp shows no response. There is no periapical lesion in the radiograph. The treatment of choice is
1. Ca(OH) Pulp capping
2. Formocresol pulpotomy
3. Conventional root canal treatment
4. Complete debridement and apexification

Endodontics Answer: 4

1) Hemisection
2) Fenestration
3) Root amputation
4) Apical curettage

Endodontics Answer: 1

The root canals most likely to share a common apical opening are
1. Mesial and distal roots of mandibular premolars
