Fibrinolysis
Enzymatic process of dissolution of fibrin. Plasmin, the main enzyme involved, degrades the fibrin mesh, leading to the production of circulating fragments that are cleared by other proteinases or organs. A normal ongoing process that dissolves fibrin and results in the removal of small blood clots. The activity of the fibrinolysin system that removes small…

Fibrin clot
Clump that results from coagulation of the blood after a sequential process by which the multiple coagulation factors of the blood interact in the coagulation cascade. Essentially composed of fibrin, this insoluble protein is formed from fibrinogen by the proteolytic action of thrombin. Called also a blood clot.

Festoons, gingival
The contours of the gingiva and oral mucosa over the roots of the teeth that tend to follow the cervical lines. These are prominent in the presence of a thin alveolar process.

Festoon
Contour of the soft tissues covering the roots of the teeth that tends to follow the cervical lines. Specifically, in prosthodontics, a carving in the base material of a denture that simulates the contours of the natural tissues being replaced by the denture. A carving that resembles scalloping or festooning in the base material of…
