BURNABY, BRITISH COLUMBIA--(Marketwire - May 23, 2012) - LED Medical Diagnostics Inc. (TSX VENTURE:LMD) announced today that Pacific Dental Services, Inc. (PDS) has agreed to purchase 400 of its VELscope Vx systems over three years. Exclusively distributed in Canada and the U.S by Henry Schein, Inc. (NASDAQ:HSID), the handheld device is the world's leading system for early detection of oral cancer and other oral disease.

"We have always enjoyed a strong relationship with Pacific Dental Services, and this agreement makes it possible for our two organizations to achieve great things together," said Peter Whitehead, CEO of LED Medical Diagnostics and its subsidiary, LED Dental. "Pacific Dental Services has an outstanding reputation for providing their affiliate dentists with opportunities to use the finest proven technologies, and we're honored they have chosen the VELscope Vx to enhance the already exceptional oral health care they provide for their patients."

The VELscope Vx is the most powerful Health Canada and FDA-approved tool to screen for oral cancer, a growing health-care issue in Canada and around the world. It is used by dentists to detect early stage oral cancer and pre-cancer, as well as other oral abnormalities such as viral, fungal and bacterial infections that might otherwise go unseen. The technology is the first to offer both cordless convenience and an optional digital camera and customized bracket that make it easy for dentists to photo-document suspicious lesions.

"Pacific Dental Services-affiliated dentists are passionate about being equipped to provide clinical excellence for their patients, and that includes detecting oral cancer and other oral diseases in their early stages," said Dr. Charles Rodgers, Vice President of Clinicians for Pacific Dental Services. "Our National Dental Advisory Board has unanimously recommended the use of the VELscope Vx at all of our affiliated locations, and we are confident that this innovative technology meets the needs of both our affiliate clinicians and their patients."

Over the past five years, LED Dental has sold more than 10,000 VELscope systems to dental practices globally. It is estimated that these devices have been used to conduct over 10 million oral cancer exams, making VELscope the world's number one adjunctive oral cancer screening technology.

Mr. Whitehead noted that the agreement gives PDS the unilateral right to terminate the purchase for any reason by July 14, 2012, as well as the unilateral right to reduce the purchase quantity to 200 units by December 31, 2012.
