NBDHE NBDHE Periodontal Assessment and Treatment 2

Question 1

A patient presents with 5-6 mm probing depths, bleeding on probing, and radiographic bone loss of 15-25%. Which AAP classification does this represent?

Accepted Answer

Stage II, Grade B

Answer

Stage II periodontitis is characterized by probing depths of 5-6 mm and radiographic bone loss of 15-33% with moderate complexity factors.

Question 2

Which instrument is best suited for removing calculus from the furcation area of a mandibular first molar?

Accepted Answer

Langer 1/2 curette

Answer

The Langer 1/2 curette is specifically designed for furcation debridement on posterior teeth and adapts well to furcation areas.

Question 3

What does the term 'clinical attachment level' (CAL) measure?

Accepted Answer

Distance from the CEJ to the base of the periodontal pocket

Answer

CAL is measured from the cementoenamel junction (CEJ) to the base of the periodontal pocket, reflecting true attachment loss.

Question 4

A patient has gingival recession of 2 mm and a probing depth of 4 mm. What is the clinical attachment level?

Accepted Answer

6 mm

Answer

When recession is present, CAL = probing depth + recession (4 mm + 2 mm = 6 mm).

Question 5

Which systemic condition is most strongly associated with increased susceptibility to periodontitis and impaired healing?

Accepted Answer

Uncontrolled type 2 diabetes mellitus

Answer

Uncontrolled diabetes impairs neutrophil function and wound healing, significantly increasing susceptibility to and severity of periodontitis.
