Sybron Dental Specialties Acquires Pentron Corporation
Securing Rights to Resilon Technology

ORANGE, CA – August 5, 2008 – Sybron Dental Specialties, Inc. announced today the addition of the Pentron brands to its corporate portfolio through the purchase of all the outstanding stock of Pentron Corporation. Daniel Even, Danaher Group Executive/President of Sybron Dental Specialties (SDS), said, “We are very enthusiastic about adding the Pentron brands to our family of companies. The crown jewel of Pentron is Resilon^®, a synthetic alternative to gutta percha, which has demonstrated through clinical review and scientific investigation to be superior to gutta percha.” Mr. Even noted that Resilon-based endodontic filling materials bond to the canal wall and minimize leakage, thereby reducing the chances of a failed root canal.

Pentron’s Resilon products will be distributed via the SybronEndo distribution channel while the balance of the Pentron brands will continue to be distributed via their current channel. Pentron customers should continue to secure products through their preferred source.
