Help & Techniques
Astringents act locally …. when applied to tissue, it causes the tissue to retract, shrivel or shrink. This limits the rate and/or amount of excretion of fluids from the tissue, causing eventual coagulation or clotting. Apply Gingi-Aid with a syringe, cotton pellet or you may soak the retraction cord with Gingi-Aid and pack into the sulcus.
Hemostyptics act locally …. when applied to a bleeding or oozing area, it attracts or captures the blood’s platelets, blocking or clogging the vessel and stops the flow of blood. The resulting coagulum (clotted blood may appear as somewhat grainy or lumpy debris) may be rinsed gently away before taking the impression. Think of styptic pencils that men use to stop the bleeding of cuts from shaving. Apply Stasis with a syringe and cotton pellet by gently burnishing (rubbing) it into the exposed capillaries, or you may soak a retraction cord with Stasis and pack into the sulcus.
Vasoconstrictors act systemically …. causing the blood vessel to constrict or become smaller in diameter …. this slows the blood flow and causes eventual clotting. Orostat is the fastest acting hemostatic available and leaves a clean, debris-free field. Apply Orostat with cotton pellet sparingly. Hold firmly in position for first few seconds or pack with slight pressure - this promotes initial absorption or vasoconstrictor action. Leave in place until seepage stops - approximately 60 seconds - remove and flush the area. A clean, blanched, clearly visible operative field will result. IMPORTANT: Solutions should not be used in combination with other hemostatic solutions or with cords impregnated with other hemostatics. Permanent tissue discoloration could occur.
