Question 1

Which rotary NiTi file system uses a reciprocating single-file motion to reduce file separation risk?

Accepted Answer

WaveOne Gold

Answer

WaveOne Gold uses reciprocating motion (clockwise-counterclockwise) which reduces cyclic fatigue and file separation compared to continuous rotation.

Question 2

What is the primary advantage of cone-beam computed tomography (CBCT) over periapical radiographs in endodontics?

Accepted Answer

Three-dimensional visualization of root anatomy and periapical pathology

Answer

CBCT provides 3D images revealing complex root morphology, missed canals, and the true extent of periapical lesions invisible on 2D films.

Question 3

Calcific metamorphosis (pulp canal obliteration) following dental trauma is best managed by:

Accepted Answer

Elective root canal treatment only if symptoms or periapical pathology develop

Answer

Most teeth with calcific metamorphosis remain vital and asymptomatic; root canal treatment is indicated only when clinical or radiographic signs of pathology appear.

Question 4

Which type of resorption is characterized by pink discoloration of the crown and widening of the coronal pulp space?

Accepted Answer

Internal resorption

Answer

Internal resorption causes the pulp tissue to resorb dentin from within, making granulation tissue visible through the crown as a pink spot.

Question 5

A tooth with a necrotic pulp and chronic apical abscess has a sinus tract but NO pain. What AAE classification applies?

Accepted Answer

Asymptomatic apical abscess

Answer

Asymptomatic apical abscess presents as a sinus tract without pain, indicating chronic drainage of a low-grade infection.
