ADC ADC - Australian Dental Council Clinical Examination and Treatment Planning Questions and Answers 2

Question 1

Which factor is MOST important when determining the restorability of a tooth?

Accepted Answer

Remaining tooth structure and crown-to-root ratio

Answer

Remaining coronal tooth structure and an adequate crown-to-root ratio are the primary determinants of whether a tooth can be successfully restored.

Question 2

What is the most appropriate first step when a patient presents with acute irreversible pulpitis causing severe spontaneous pain?

Accepted Answer

Perform pulpectomy or extraction to relieve the pain

Answer

Acute irreversible pulpitis requires removal of the inflamed pulp tissue (pulpectomy or extraction) to provide definitive pain relief.

Question 3

In treatment planning for a patient with multiple failing restorations and active caries, which phase should be completed first?

Accepted Answer

Disease control (stabilisation) phase

Answer

The disease control (stabilisation) phase addresses active disease — caries removal, infection control, and extraction of hopeless teeth — before any definitive treatment.

Question 4

A patient reports biting the inside of their cheek repeatedly and presents with a nodule on the buccal mucosa. What is the most likely diagnosis?

Accepted Answer

Fibroma (irritation fibroma)

Answer

Repeated trauma from cheek biting commonly causes reactive fibrous hyperplasia (irritation fibroma), the most common benign soft tissue lesion in the oral cavity.

Question 5

Which clinical sign indicates inadequate ferrule effect when planning a crown for an endodontically treated tooth?

Accepted Answer

Less than 2 mm of sound tooth structure above the crestal bone

Answer

A ferrule requires at least 2 mm of sound, parallel dentinal walls above the finish line; less than this compromises crown retention and fracture resistance.
