OptiBond FL Named REALITY 2007 Product of the Year

ORANGE, CA - June 28, 2007 - Fifteen years after its introduction and still regarded as the gold standard in adhesive dentistry, it comes as no surprise that OptiBond FL^® adhesive from Kerr was announced winner of the REALITY 2007 Product of the Year Award.

"We're delighted that REALITY has recognized OptiBond FL as Product of the Year," says Meghan Moore Rizzo, Director of Product Management at Kerr. "The long-term clinical performance of the OptiBond brand is second-to-none, combined with Kerr competencies in adhesive system technologies to support a family of adhesives of all generations - from OptiBond FL through OptiBond All-in-One. It takes a remarkable product to carry the OptiBond name. And with 13-year clinicals, OptiBond continues to set the standard for bonding agents industry-wide."

OptiBond® was the first filled, fluoride-releasing total-etch adhesive bonding system on the market, a dualcure material indicated for direct and indirect metal-free applications. OptiBond FL (Filled, Light-cure) followed, also a highly filled light-cure adhesive offering a simple two-bottle delivery process. OptiBond FL is used for direct restorations as well as indirect core buildup.

After earning a 2005 REALITY Five Star Award, in 2006 OptiBond FL received the REALITY 20th
Anniversary Legacy Award, celebrating its extraordinary long-term clinical performance and an enduring reputation among dental professionals for proven adhesive strength and versatility - as well as introducing a new Unidose® delivery option.
