On a periapical radiograph, a vertical root fracture classically produces radiolucency in which distribution?
Show answer and explanation
Correct answer: C. A combined apical-and-lateral ('J-shaped' or halo) radiolucency
Vertical root fractures often produce a combined apical-and-lateral bony defect that can appear as a 'J-shaped' or halo radiolucency along the fracture line, though the fracture line itself is frequently not directly visible because of its orientation relative to the X-ray beam.
