Recent Extraction Site (Radiology)

How does a recent extraction site appear on a radiograph?

A radiolucent extraction socket with a clearly defined radiopaque bundle-bone outline.

What is a bundle bone?

The radiopaque bone lining the tooth socket where the periodontal ligament fibers were attached.

What happens to the extraction socket during healing?

*New bone is deposited into the socket

*The radiolucent socket gradually fills in

*The bundle bone slowly fades

*After about 18 months, the socket can no longer be distinguished from surrounding bone

How can you distinguish a recent extraction site from pathology?

A recent extraction site has a well-defined socket outline (bundle bone) and a history of extraction. It is a normal healing finding, not a disease.
