Edge: Well-localized.

Shape: Radiates away from the source of inflammation, typically the apex of a tooth.

Internal: Radiopaque, radiopacity of bone.

Other: It may be associated with rarefying osteitis and/or a widened periodontal ligament space but it may also be solitary.

Number: May be single or multiple.
