ADEX Periodontal Concepts 5

Question 1

What is the significance of the mucogingival junction (MGJ) in periodontal assessment?

Accepted Answer

It is the boundary between attached gingiva and alveolar mucosa

Answer

The MGJ is the fixed anatomical boundary between keratinized attached gingiva and the non-keratinized, mobile alveolar mucosa.

Question 2

A patient on long-term bisphosphonate therapy for osteoporosis requires periodontal surgery. The primary concern is:

Accepted Answer

Risk of medication-related osteonecrosis of the jaw (MRONJ)

Answer

Bisphosphonates inhibit osteoclast-mediated bone remodeling, increasing the risk of medication-related osteonecrosis of the jaw (MRONJ) following invasive procedures.

Question 3

In the 2017 AAP/EFP classification system, Grade reflects which aspect of periodontitis?

Accepted Answer

The rate of disease progression, risk factors, and systemic impact

Answer

Grade (A, B, or C) describes the rate of periodontitis progression, evidence of direct and indirect risk factors, and the disease's potential systemic impact.

Question 4

Which systemic condition is associated with Papillon-Lefèvre syndrome, which causes severe early-onset periodontitis?

Accepted Answer

Mutations in the cathepsin C gene causing neutrophil dysfunction

Answer

Papillon-Lefèvre syndrome is caused by mutations in the cathepsin C gene, leading to impaired neutrophil function and severe periodontitis beginning in primary dentition.

Question 5

Which periodontal parameter best predicts future attachment loss at a specific site?

Accepted Answer

BOP combined with suppuration and increased probing depth

Answer

The combination of BOP, suppuration, and increased probing depth at the same site is the strongest clinical predictor of active disease and future attachment loss.
