BIOLASE ANNOUNCES PRELIMINARY FOURTH QUARTER REVENUE

IRVINE, CA (January 7, 2008) . . . BIOLASE Technology, Inc. (NASDAQ:BLTI), the world’s leading dental laser company, announced today that, based on a preliminary review of its financial performance, the Company expects to report net revenue of greater than $20 million for the fourth quarter ended December 31, 2007, the highest level of quarterly revenue recorded to date at BIOLASE. Revenue is estimated to have rebounded from $12.8 million in the 2007 third quarter and also should compare favorably to the previous record revenue of $19.8 million for the 2006 fourth quarter.

Federico Pignatelli, Director and Interim Chief Executive Officer during the period, commented, “The strong revenue growth in the fourth quarter was due in part to increased demand and improved corporate focus on working with our US distribution partner Henry Schein. We are extremely pleased with the improvement in operations during the quarter.”

The Company will provide additional details on a quarterly conference call and webcast following its fourth quarter 2007 operating results report in early March. Investors are also invited to listen to the previously announced webcast of the Company’s presentation at the Needham & Company Growth Stock Conference on January 8, 2008.
