Question 1

A patient presents with a deep periodontal pocket, vertical bone loss, and a positive furcation involvement on a mandibular molar. Which classification best describes a furcation defect that can be probed through but is not visible clinically?

Accepted Answer

Glickman Grade III

Answer

Glickman Grade III is a through-and-through furcation that can be probed completely but remains covered by soft tissue and is not clinically visible.

Question 2

Which local anesthetic is contraindicated in patients with a documented allergy to para-aminobenzoic acid (PABA)?

Accepted Answer

Benzocaine
