NEWS RELEASE for May 9, 2006

BIOLASE ANNOUNCES FIRST QUARTER 2006 RESULTS;

MANAGEMENT AND BOARD CHANGES

IRVINE, CA (May 9, 2006) - BIOLASE Technology, Inc. (NASDAQ:BLTI), a medical technology company that develops, manufactures and markets lasers and related products focused on technologies for improved applications and procedures in dentistry and medicine, today reported operating results for the first quarter ended March 31, 2006. The Company also announced that Robert E. Grant, the Company’s President, CEO and Acting Chairman of the Board, resigned from those positions effective today to accept a position in the medical aesthetics industry. The Company also announced today the appointment of Jeffrey W. Jones as the Company’s President and Chief Executive Officer and George V. d’Arbeloff as the Company’s Chairman of the Board.

First Quarter 2006 Results

Net revenue for the quarter ended March 31, 2006 was $16.9 million compared with $16.8 million for the first quarter of 2005. The gross margin for the first quarter of 2006 was 52 percent of net revenue as compared with 56 percent of net revenue in the same period of 2005. Loss from operations for the first quarter of 2006 was $2.2 million versus $4.3 million in the same quarter of 2005. Net loss for the quarter ended March 31, 2006 was $2.3 million, or $0.10 per diluted share, compared with $4.3 million, or $0.19 per diluted share, for the quarter ended March 31, 2005.

Loss from operations for the first quarter of 2006 included a $0.4 million charge related to 45,208 shares of BIOLASE common stock placed into escrow in January 2005 in connection with the Diodem patent litigation settlement. The settlement agreement provided that the shares would be released to Diodem if certain criteria were met on or before July 2006. The Company has determined it is probable that the shares will be released, and thus recorded in the first quarter of 2006 a non-cash charge based on the fair value of the escrowed shares as of March 31, 2006.

The Company’s President and CEO, Jeffrey W. Jones, commented on the quarterly results, saying, “During the quarter, we made significant progress toward our goals of improved profitability and cash flow management. Our operating expenses declined by approximately $2.7 million as compared to the same period in 2005. While approximately $2.0 million of the decrease was related to the first quarter 2005 purchase from SurgiLight of a license in the field of ophthamology, our general and administrative expenses declined by approximately $1.2 million, or 27 percent, despite the recording of approximately $0.2 million in compensation expense resulting from the adoption of the new stock option accounting rules. Accordingly, our loss from operations for the first quarter of 2006 decreased to $2.2 million compared with $4.3 million in the same quarter of 2005. And more importantly, because of our focus on reducing costs and improving our working capital management, we lowered our cash used in operations from $10.0 million in the first quarter of 2005 to only $1.1 million in this year’s first quarter.”

Commenting on the state of the business, Jones added, “We are very excited about the opportunities for the Company over the coming quarters. We have made great strides in late 2005, and so far this year, in improving our operating cash flow. With the recent enhancements in the performance and reliability of the Waterlase MD system, we expect gradual improvement in profitability in the later part of 2006. Critical indicators in our business, such as increased laser system placements in dental schools and greater sales levels at recent trade shows, are bolstering our confidence in achieving our goals of cash flow generation, profitability and revenue growth in 2006.”

Management and Board Changes

Effective today, Robert E. Grant, President, CEO and Acting Chairman, has resigned from those positions and as a member of the Board of Directors to accept a position in the medical aesthetics industry. Additionally, the Company appointed Jeffrey W. Jones as President and CEO and George V. d’Arbeloff, as Chairman of the Board.

Mr. Jones commented, “We are grateful to Robert for his many accomplishments at BIOLASE and we wish him all the best in his new opportunity. During Robert’s tenure, the Company made significant progress on many fronts. My job will be to build on that progress. Our vision and strategies are clear. I believe strongly in the strength of our future and I welcome this exciting opportunity.”

George V. d’Arbeloff, Chairman of the Board, said, “We are fortunate to have an experienced executive such as Jeff Jones within our ranks to take over the leadership role of the Company at this time. The Board believes the Company is well-positioned to leverage Jeff’s skills and those of the rest of our executive management team to execute our strategy and drive significant growth for the benefit of our shareholders. We appreciate Robert’s many contributions to the Company over the past three years and we wish him well in his future endeavors.”

Robert E. Grant, former President and CEO, commented, “I am proud of the Company’s accomplishments during my service as Chief Executive Officer. With its market leading position in dental lasers, improving financial condition, and exciting developments underway, I believe BIOLASE will be tremendously successful. From 1999 to 2004, during his previous tenure as CEO, Jeff Jones established the Company as the world leader of dental lasers, growing the Company from approximately $1 million to $60 million in revenue. With his strong experience and leadership skills, I am very confident that Jeff will successfully lead BIOLASE to its next level of growth and development.”
