Endodontics · single question

The characteristic radiographic appearance of a vertical root fracture is:

A combined lateral (along the root) and periapical radiolucency, often 'J-shaped' or 'halo'
A well-defined periapical radiolucency only
Generalized horizontal bone loss
A radiopaque mass at the apex

Show answer and explanation

Correct answer: A. A combined lateral (along the root) and periapical radiolucency, often 'J-shaped' or 'halo'

A. Correct. Vertical root fractures classically produce a radiolucency that extends along the lateral aspect of the root and around the apex (a 'J-shaped' or 'halo' pattern) due to bone loss along the fracture line.
B. An isolated periapical radiolucency is more typical of pure endodontic pathology.
C. Generalized horizontal loss is a periodontitis pattern, not a fracture.
D. A radiopaque apical mass suggests condensing osteitis/cementoma, not a fracture.
