NEWS RELEASE for May 8, 2007

BIOLASE REPORTS FIRST QUARTER 2007 RESULTS

IRVINE, CA (May 8, 2007) — BIOLASE Technology, Inc. (NASDAQ:BLTI), the world’s leading dental laser company, today reported operating results for its first quarter ended March 31, 2007. These results are in line with the preliminary results that were announced on April 11.

Net revenue for the quarter ended March 31, 2007 was $15.1 million compared with $16.9 million for the first quarter of 2006. Net domestic revenue for the first quarter of 2007 was $8.7 million as compared with $10.4 million in the 2006 first quarter. Net international revenue in the first quarters of 2007 and 2006 was $6.4 million and $6.5 million, respectively.

Gross profit for the first quarter of 2007 improved to 54 percent of net revenue as compared with 52 percent of net revenue in the same period of 2006. Operating expenses in the 2007 first quarter declined by nine percent, or $1.0 million, to $10.0 million from $11.0 million in the first quarter of 2006. Net loss for the quarter ended March 31, 2007 narrowed to $1.7 million, or $0.07 per diluted share, compared with a net loss of $2.3 million, or $0.10 per diluted share, for the first quarter of 2006.

President and CEO Jeffrey W. Jones commented, “During the quarter, we continued to make progress in key operational areas, especially in our ongoing cost containment programs, which we expect will yield significant benefits as revenue trends improve in the coming periods. Despite lower revenues from products and services, the gross margin as a percentage of sales was only 0.7 percent lower in the first quarter this year compared with the same quarter of 2006. Additionally, our efforts resulted in a nine percent operating expense reduction in this year’s first quarter as compared to last year’s. We believe our current infrastructure and cost structure position us well for bottom-line improvement in 2007.”

Jones continued, “We have been highly engaged with the management of Sullivan-Schein Dental with the shared goal of benefiting from our experience in the first quarter. As a result, we are refining the allocation of our sales representatives’ time between selling and relationship-building activities with the Schein sales representatives in the field, and we have kicked off programs we believe will have a positive impact on sales. We’re getting an excellent start in our first full quarter of selling the new ezlase™ 940 soft-tissue diode dental laser system. And, we are already launching new accessories and disposables to expand what a dentist can do with the Waterlase MD™ and increase its efficiency and speed. Currently, we are launching our single patient use disposable ZipTips™ and our new Waterlase MD Gold™ handpiece. This is just the beginning of exciting new initiatives we believe will contribute to significant revenue growth, with increased consumables sales, in 2007.”
