ORE Part 2 Oral Surgery & Extractions

Question 1

What is the most common complication following a mandibular third molar extraction?

Accepted Answer

Dry socket (alveolar osteitis)

Answer

Dry socket (alveolar osteitis) is the most common post-extraction complication, occurring in 2–5% of routine extractions and up to 30% of lower third molar removals.

Question 2

What landmark must be identified to deliver an inferior alveolar nerve block (IANB)?

Accepted Answer

Pterygomandibular raphe and coronoid notch

Answer

The IANB is delivered medial to the pterygomandibular raphe, at the level of the coronoid notch (deepest concavity of the anterior ramus), guiding the needle to the mandibular foramen.

Question 3

In the Pell and Gregory classification, a Class C position of a lower third molar indicates?

Accepted Answer

The tooth is level with or below the cervical line of the second molar

Answer

Pell and Gregory Class C means the highest point of the third molar is below the cervical line (CEJ) of the adjacent second molar, indicating deep impaction.

Question 4

What is the most appropriate management of a tooth with a periapical abscess and severe bone loss in a medically compromised patient on bisphosphonates?

Accepted Answer

Thorough assessment and MDT discussion before extraction; consider endodontic treatment

Answer

Bisphosphonate therapy creates risk of medication-related osteonecrosis of the jaw (MRONJ); extraction decisions require MDT input, ideally endodontic treatment is preferred to avoid extraction.

Question 5

Which instrument is used to section a lower third molar before removal to reduce trauma?

Accepted Answer

Surgical handpiece with a fissure bur

Answer

A surgical handpiece with a fissure bur is used to section the crown or roots of a lower third molar, reducing the surgical access required and minimising trauma.
