Milestone Scientific Receives Purchase Orders For Single Tooth Anesthesia (STA(TM)) System From Henry Schein, Inc.

LIVINGSTON, N.J., Feb. 7 /PRNewswire-FirstCall/ -- Milestone Scientific, Inc. , the recognized leader in advanced injection technologies, today announced that in anticipation of the formal product launch and commercial availability of its new Single Tooth Anesthesia (STA(TM)) Delivery System later this quarter, Henry Schein, Inc. has issued Milestone initial purchase orders for 500 STA Delivery Systems, 24 CompuDent(TM) systems and a range of related disposable products used in conjunction with both systems. The orders, collectively representing over $1.67 million in initial revenue to Milestone, are expected to begin being fulfilled in the first quarter with actual revenue recognition occurring upon shipments.

Last month, Milestone and Henry Schein, the largest provider of healthcare products and services to office-based practitioners in the combined North American and European markets, announced that the companies entered a distribution agreement granting Henry Schein exclusive distribution rights to market Milestone's Single Tooth Anesthesia (STA(TM)) Delivery System and other products to dental professionals in the United States and Canada.

Commenting on the initial orders, Leonard Osser, Chairman and Chief Executive Officer of Milestone, stated, "It is clear that Henry Schein shares our expectations for a favorable response to the upcoming product launch of the STA Delivery System. Aside from marking a critical business achievement for Milestone, these orders, coupled with anticipated near term sales of the STA Delivery System, are expected to contribute measurably to our Company's fundamental growth in 2007."

Milestone's STA Delivery 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 tongue. The STA Delivery System uses Milestone's patented CompuFlo(TM) with Dynamic Pressure Sensing (DPS(TM)) 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 Delivery System is the first commercial application using this advanced real time pressure sensing technology.
