How does an acute dentoalveolar abscess appear on a periapical radiograph?
Show answer and explanation
Correct answer: C. Often NOT visible on radiograph in the acute stage
C) Often NOT visible on radiograph in the acute stage — CORRECT.
An ACUTE abscess represents a rapid purulent process. Bone destruction may not yet be sufficient to produce visible radiographic changes — bone loss must be ~30–50% to appear on a 2D radiograph. Radiographic changes (periapical radiolucency) are more characteristic of CHRONIC abscesses. Clinically: acute abscesses present with swelling, pain, and fluctuance without necessarily having radiographic confirmation.
A) Well-circumscribed halo: Describes a periapical granuloma or cyst — chronic lesions.
B) Associated with a tooth: True but incomplete; the key INBDE point is that acute abscesses may not show radiographic changes yet.
D) Radiopacity: Not characteristic of any abscess.
