Question 1

Which local drug delivery agent can be placed subgingivally as an adjunct to mechanical debridement?

Accepted Answer

Minocycline microspheres or doxycycline gel

Answer

Locally delivered antibiotics such as minocycline microspheres (Arestin) or doxycycline gel can be placed subgingivally to achieve high local drug concentrations as adjuncts to debridement.

Question 2

What is the main limitation of panoramic radiography for periodontal assessment?

Accepted Answer

Magnification distortion and inability to resolve early interproximal bone loss accurately

Answer

Panoramic radiographs have geometric distortion and lower resolution, making them less accurate than periapical films for detecting early interproximal bone loss.

Question 3

What does a positive vertical percussion test in a periodontally involved tooth suggest?

Accepted Answer

Acute inflammation in the periodontal ligament

Answer

Positive vertical percussion indicates acute inflammation or oedema in the periodontal ligament space, which can be associated with acute periodontal abscess or lateral abscess.

Question 4

Which surgical technique is used to achieve root coverage for isolated recession defects?

Accepted Answer

Connective tissue graft (subepithelial)

Answer

The subepithelial connective tissue graft (SCTG) is considered the gold standard for root coverage of Miller Class I and II recession defects.

Question 5

What is the minimum duration of supportive periodontal therapy (SPT) intervals recommended for high-risk periodontal patients?

Accepted Answer

Every 3 months

Answer

High-risk periodontal patients (Grade C, multiple risk factors, previous disease history) should be recalled every 3 months to monitor and maintain treatment outcomes.
