CUSTOMER TESTIMONIALS

Dear Sir,

I began using your product, ActCel, approximately 18 months ago. I was first introduced to ActCel by one of your representatives during our annual convention. Previous to this, I used Gelfoam.

Although reluctant at first, I found myself only using ActCel as my hemostatic adjunct. Some of the features I liked Included:

• Dispensed in individual sterile pouches
• Easy to cut to any size or shape
• Rapidity of clotting action

James M. Huoni, D.M.D

Enclosed are a few pictures of me using Hemostatic Gauze. For the last five years, I have used it in all of the lower third molar sockets of about 3000 patients to prevent dry socket. I found it to be very effective. Though a general dentist, my practice is limited to oral surgery. I use a nurse anesthetist and do cases under IV sedation in about 25 different offices along the Wasatch Front. I teach courses on oral surgery throughout the U.S. and have been presenting for Clinical Research Associates since Dr. Christensen's departure for his sabbatical.

These dissolvable pieces are one inch square - one in each lower socket. I also use it on Coumadin patients and in other cases where bleeding is expected.

Sincerely,

Karl R. Koerner, BS, DDS, MS
