NBDHE NBDHE Periodontal Assessment and Treatment 3

Question 1

Which furcation classification indicates through-and-through involvement where a probe passes completely between the roots?

Accepted Answer

Class III

Answer

Class III furcation involvement means the furcation is open through-and-through, allowing a probe to pass completely from one side to the other.

Question 2

What is the primary rationale for performing a frenectomy as part of periodontal treatment?

Accepted Answer

Eliminate a frenum pull that impedes oral hygiene or causes gingival recession

Answer

A frenectomy is indicated when frenum attachment causes tissue pull that compromises oral hygiene access or contributes to gingival recession.

Question 3

Necrotizing ulcerative gingivitis (NUG) is characterized by which classic triad of findings?

Accepted Answer

Interdental papilla necrosis, pain, and fetid odor

Answer

NUG presents with the classic triad of punched-out interdental papillae (necrosis/ulceration), severe pain, and characteristic fetid breath (fetor ex ore).

Question 4

Which of the following local drug delivery agents is placed subgingivally to reduce pocket depth as an adjunct to SRP?

Accepted Answer

Minocycline microspheres (Arestin)

Answer

Minocycline microspheres (Arestin) are a subgingival local drug delivery system placed directly into periodontal pockets as an adjunct to scaling and root planing.

Question 5

A patient has 30% bone loss on the mesial of tooth #30 with a 6 mm probing depth. The tooth has a good prognosis. What is the most appropriate initial treatment?

Accepted Answer

Scaling and root planing followed by re-evaluation

Answer

SRP (cause-related therapy) is always the first step in active periodontal treatment; surgical decisions are made only after evaluating the tissue response to nonsurgical therapy.
