Product Details

An aqueous, 15.5% ferric sulfate hemostatic solution with a pH of ~1.0.

  • Known as the “Classic” hemostatic agent
  • Stops bleeding in seconds
  • Eliminates sulcular fluid contamination for optimal bonding
  • Decreases costly impression remakes


"Highly recommended as effective and easy to use for control of bleeding, tissue management, and pulpotomies. Rating +++++.”1 Astringedent is well-suited for a variety of dental and oral surgery procedures to arrest surface capillary bleeding. Such procedures include fixed prosthodontics, restorative-operative, periodontal treatment, etc. Astringedent is also recommended for retrofillings, canine impactions, gingivectomies, and as a ‘“fixative” for pulpotomies. Astringedent can be used to prevent leakage caused by sulcular fluid contamination during direct bonding procedures. Soak an Ultrapak® cord in hemostatic and isolate the tissues. Follow with a firm air/water spray.

Tissue Management Technique Step by Step

  1. 1

    ​Burnish the hemostatic agents firmly against the sulcus until bleeding stops. (No more coagulum forms.)
  2. 2

    ​A blunt, bent cannula with padded "scrub brush" enables infusing and cleaning in the cut sulcus.
  3. 3

    ​Apply firm air/water spray to remove residual coagulum and test tissue for quality, profound hemostasis. If bleeding continues, repeat infusion technique.
  4. 4

    ​After complete hemostasis has been reached, excellent retraction is achieved through the use of Ultrapak® knitted cord.
