About hemostatic agents & paste
These are the chemicals used with a cord or in place of one: vasoconstrictors that make blood vessels constrict, astringents that shrink the gum tissue, and substances that stop bleeding by clotting. Aluminium chloride at 5 to 25 percent is commonly used as an astringent, as a solution or a gel, and works by constricting damaged vessels to give a dry field. Ferric sulfate at 15 to 20 percent is used as an astringent and styptic, and works by agglutinating blood proteins, which form plugs that occlude the capillary openings. Epinephrine has been used as a displacement medicament, and published work reports that it can cause significant systemic side effects.
The chemical part: it stops the bleeding and dries the field rather than pushing the tissue aside. A retraction paste works without a cord: one widely used paste is kaolin with aluminium chloride, and it swells on contact with crevicular fluid.
