The radiolucency surrounding the apex of the maxillary right lateral incisor indicates the presence of which finding?

• A. Pulpal inflammation
• B. Bone loss
• C. Periapical cyst
• D. Normal anatomy

Answer: (B)

Radiolucency around the apex signals loss of bone density in that area. This reflects bone destruction or thinning due to a periapical inflammatory process, usually stemming from pulpal necrosis or infection that has reached the surrounding bone. Pulpal inflammation itself resides inside the tooth and does not by itself create a radiolucent area at the root tip on a radiograph. A periapical cyst is a possible specific cause of a radiolucent periapical lesion, but radiographs alone can’t confirm a cyst; they only show the bone loss around the apex. Normal anatomy would show intact lamina dura and no surrounding radiolucency, so the observed radiolucency best indicates bone loss.
