Crevicular fluid
The fluid that is typically produced in the presence of inflammation and seeps through the crevicular epithelium; it can serve as a defense mechanism against infection by carrying antibodies and other substances into the sulcus. Also known as sulcular fluid and gingival fluid.

Crepitus (crepitation)
A crackling or grating noise in a joint during movement.

This sound is reminiscent of footsteps on a…
