Question 1

Which periodontal probe reading indicates pathological pocketing in a healthy adult?

Accepted Answer

Greater than 3 mm

Answer

Probing depths greater than 3 mm are generally considered pathological, as healthy sulcus depth is 1–3 mm.

Question 2

Which local factor is most strongly associated with the initiation of periodontal disease?

Accepted Answer

Dental plaque (biofilm)

Answer

Dental plaque biofilm is the primary initiating factor of periodontal disease, triggering the host inflammatory response.

Question 3

In the AAP/EFP 2017 periodontal classification, which stage indicates tooth loss due to periodontitis?

Accepted Answer

Stage IV

Answer

Stage IV periodontitis includes complexity factors such as tooth loss attributable to periodontitis and masticatory dysfunction.

Question 4

What does a positive bleeding on probing (BOP) primarily indicate?

Accepted Answer

Active gingival inflammation

Answer

Bleeding on probing is a reliable indicator of active gingival inflammation due to increased vascularity and ulceration of the sulcular epithelium.

Question 5

Which systemic condition is most bidirectionally linked to periodontal disease?

Accepted Answer

Diabetes mellitus

Answer

Diabetes mellitus has a well-established bidirectional relationship with periodontitis — poor glycemic control worsens periodontitis, and untreated periodontitis worsens glycemic control.
