CPT CPT Radiographic Analysis & Bone Assessment

Question 1

Which radiographic technique provides the most accurate image of alveolar bone levels?

Accepted Answer

Periapical radiograph with paralleling technique

Answer

Panoramic radiograph

Answer

Bitewing radiograph

Answer

Occlusal radiograph

Question 2

On a periapical radiograph, normal alveolar bone crest height is typically located:

Accepted Answer

1–2 mm apical to the CEJ

Answer

At the cementoenamel junction (CEJ)

Answer

3–4 mm apical to the CEJ

Answer

At the midroot level

Question 3

Horizontal bone loss on a radiograph indicates:

Accepted Answer

Even bone resorption affecting multiple teeth at a similar level

Answer

Localized aggressive periodontitis pattern

Answer

Vertical defect pattern

Answer

Furcation involvement only

Question 4

A triangular-shaped radiolucency at the interproximal crest most likely suggests:

Accepted Answer

Early bone loss due to periodontitis with loss of lamina dura

Answer

Normal anatomical variation

Answer

Periapical abscess formation

Answer

Cementum resorption only

Question 5

Which radiographic finding is most consistent with localized aggressive periodontitis?

Accepted Answer

Arc-shaped vertical bone loss around first molars and incisors

Answer

Generalized horizontal bone loss

Answer

Diffuse calculus deposits throughout

Answer

Uniform bone height on all teeth

Question 6

Furcation involvement is radiographically evident when:

Accepted Answer

Radiolucency is visible in the furcation area between roots

Answer

The periodontal ligament space widens at the apex

Answer

The lamina dura completely disappears

Answer

Root resorption is present at the apex
