Question 1

According to the Andreasen classification, which fracture involves enamel and dentin WITHOUT pulp exposure?

Accepted Answer

Uncomplicated crown fracture

Answer

An uncomplicated crown fracture involves enamel and dentin but does not expose the dental pulp, hence 'uncomplicated.'

Question 2

What is the most appropriate endodontic treatment for a permanent tooth with a complicated crown fracture (pulp exposure) and an open apex in an adolescent patient?

Accepted Answer

Cvek pulpotomy (partial pulpotomy) to preserve apexogenesis

Answer

A Cvek (partial) pulpotomy preserves vital pulp tissue and allows continued root development (apexogenesis) in immature permanent teeth.

Question 3

Which luxation injury involves displacement of the tooth in a non-axial direction with accompanying alveolar bone fracture?

Accepted Answer

Lateral luxation

Answer

Lateral luxation involves displacement in a non-axial direction and is always accompanied by comminution or fracture of the alveolar bone.

Question 4

Which luxation injury carries the POOREST prognosis for pulp survival in permanent teeth?

Accepted Answer

Intrusive luxation

Answer

Intrusive luxation has the poorest pulp survival prognosis due to severe crushing and severing of the apical neurovascular supply during axial displacement.

Question 5

What is the appropriate management of an intruded permanent tooth with a CLOSED apex in an adult patient?

Accepted Answer

Immediate orthodontic or surgical repositioning

Answer

Intruded permanent teeth with closed apices in adults require orthodontic or surgical repositioning, as spontaneous re-eruption is unlikely in mature teeth.
