Flashcards

Residual Cyst

A cyst that persists after the removal of a tooth. It arises from residual epithelial remnants that are left behind after the extraction.

Inflammatory Collateral Cysts

These cysts are often found on the buccal side of the roots of teeth that haven't fully erupted. They involve inflammation.

Enucleation (of an Inflammatory Collateral Cyst)

The surgical removal of the cystic lesion.

Buccal Bifurcation Cyst

A well-defined, round radiolucent area on an X-ray, indicating a cyst that's located at the junction where the tooth's roots branch out (bifurcation).
