SAN CLEMENTE, Calif.--(BW HealthWire)--Dec. 23, 1998--BIOLASE TECHNOLOGY, INC. (NASDAQ SmallCap - BLTI) today announced the addition of the Diode laser to its market leading dental product line. The diode laser has emerged to be a highly respected and coveted tool in today's dental practice.

Commenting about the BIOLASE LD-15 diode system, Dr. David S. Hornbrook, DDS, FAACD, and Director of P.A.C. Live at the University of Pacific, San Francisco; "If I had to name one instrument in my office that has taken my aesthetic practice to the next level, it would be the LD-15 diode laser." Dr. Hornbrook further commented, "I have tried other diode lasers in the past, but none compare to the design and usability...It (BIOLASE LD-15) stands head and shoulders above any competition."

There have been extensive studies showing the diode, and particularly the advanced BIOLASE LD-15, to be effective for many clinical applications. Dr. Andreas Moritz, at the University of Vienna, along with Dr. Gutknecht at Aachen University, have used the LD-15 as the standard for their research on the clinical efficacy of the diode laser. Moritz and Gutknecht have found the laser to be very effective for many soft tissue procedures as well as bacteria reduction.

Jones, newly appointed President and CEO of BIOLASE, remarked "This new product has won the respect and acceptance of leading dentists.

Having both systems further strengthens BIOLASE's position in the dental market."
