MDS PREP

Moderate extrusion of obturating material and sealer beyond the apex is undesirable because
1) The prognosis is poor
2) There is likelihood of postoperative discomfort
3) Sealer is usually not resorbed and gutta-percha may cause severe perirdicular reaction in periapical tissue
4) All of the above

Endodontics Answer: 4

Lentulo spirals are used for
1) Locating canal orifice
2) Pulp extirpation
3) Enlarging coronal third of the root canal
4) Application of root canal sealer

Endodontics Answer: 4

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

In periapical surgery, which of the following flap designs limits access to the operative site and often heals with scar formation
1. Envelope
2. Rectangular
3. Triangular
4. None of the above

Endodontics Answer: 1

Which of the following is most likely to cause complete obturation of pulp space
1) A deep restoration without base
2) A deep blow to tooth where tooth was injured and not devitalised
3) Normal calcification process in middle age
4) A deep carious lesion

Endodontics Answer: 2

In the mandibular arch, the greatest lingual inclination of the crown from its root is seen in the permanent
1) Canine
2) Third molar
3) First premolar
4) Central incisor

Endodontics Answer: 3

In which of the following conditions single visit root canal treatment non-recommended
1) The pulp is not symptomatic but necrotic
2) The pulp is symptomatic and necrotic
3) The pulp is vital and asymptomatic
4) The pulp is necrotic with a draining sinus

Endodontics Answer: 4

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
