Advanced Dental Device to Be Available in the First Quarter, 2007

LIVINGSTON, N.J. & MELVILLE, N.Y.--(BUSINESS WIRE)--Jan. 16, 2007--Milestone Scientific, Inc. (OTCBB:MLSS), the recognized leader in advanced injection technologies and Henry Schein, Inc. (Nasdaq:HSIC), the largest provider of healthcare products and services to office-based practitioners in the combined North American and European markets, today announced that the companies have signed a distribution agreement granting Henry Schein exclusive distribution rights to market Milestone's Single Tooth Anesthesia (STA(TM)) system and other products to dental professionals in the United States and Canada.

Milestone's STA system is designed to allow dentists to immediately administer the periodontal ligament injection, to anesthetize a single tooth, without first administering a mandibular block that anesthetizes an entire quadrant of the jaw. The periodontal ligament injection is highly valued among dentists and the Milestone system allows it to be more efficiently administered, while avoiding collateral numbing of the cheek, lips and jaw. The STA system uses Milestone's patented CompuFlo(TM) pressure sensing technology to provide the dentist with valuable information on the pressures created in the tissue being injected. The patented CompuFlo technology is believed to have broad applications in medicine and dentistry and STA system is the first commercial application using this advanced, real time pressure sensing technology.

"At Sullivan-Schein Dental, we are committed to offering our customers technologically advanced exclusive products to enhance the practice of dentistry, and Milestone's STA system is an important addition to that roster," said Tim Sullivan, President of Sullivan-Schein Dental, Henry Schein's U.S. Dental division. "We are very pleased to be teaming with Milestone to make the STA system available to our dental customers in the United States and Canada."

Leonard Osser, Milestone's Chairman and CEO, added, "The development of our STA system is the culmination of many years work to develop a more dentist friendly and more efficient system for painlessly anesthetizing a single tooth. We believe that the STA system should set a new standard of patient care and are pleased that the world's leading dental distribution company shares our vision."
