Gelfoam® Dental Sponges are sterile, surgical sponges prepared from a specially treated and purified gelatin solution and are absorbable. In oral and dental surgery, Gelfoam Dental Sponges are an aid in providing hemostasis (cessation of bleeding). Gelfoam may be used either dry or moistened, depending upon conditions present at operation and preference of the surgeon. Isotonic saline is suitable for use with Gelfoam. Although not necessary, Gelfoam can be used either with or without thrombin to obtain hemostasis.
