[Hematology and dentistry. Part III. Fibrin formation disorder]

After the formation of a platelet-plug, generation of fibrin is necessary for its stabilization. Both congenital and acquired deficiencies of clotting factors occur, leading to retarded formation of fibrin. In congenital disorders, preoperative correction is possible and necessary. In acquired deficiencies, the type and feasibility of correction depends on the cause of the deficiency.
