NEWS RELEASE for April 6, 2011

BIOLASE ANNOUNCES THAT IT EXPECTS REVENUES FOR FIRST QUARTER TO
EXCEED PREVIOUS GUIDANCE

Net Revenue Expected to Total Approximately $10.4 Million,
an Increase of 136 Percent over Q1, 2010

IRVINE, CA (April 6, 2011) — BIOLASE Technology, Inc. (NASDAQ:BLTI), the world’s leading dental laser manufacturer and distributor, announced today that, based on a preliminary review of its financial performance, the Company expects to report net revenue of approximately $10.4 million for the first quarter ended March 31, 2011. This is an increase of approximately 10 percent from the updated guidance provided last month in the mid-range of $9.5 million ($9.25 million to $9.75 million) and an increase of approximately 136 percent from $4.4 million of net revenue for the first quarter ended March 31, 2010.

Federico Pignatelli, Chairman and CEO, said, “We are pleased with the better than expected revenues that we believe we have achieved during the first quarter, traditionally our slowest quarter of the year. Our recently expanded direct sales force in North America and several of our international distributors have contributed to the growing sales traction in the period and a strong initial demand for our new flagship all-tissue laser system launched in January, the WaterLase^® iPlus™, have all contributed to the quarter performance. Orders for the WaterLase iPlus have exceeded our expectations, and we are working diligently to manufacture enough to keep up with the current demand. The launch of the Waterlase iPlus is shaping up to become the most successful in the history of the Company and we believe it will be a strong contributor to our future revenue growth. Demand for our wireless iLase™ five watt diode laser system also remained strong in the period as we continued to receive new orders and work through our existing backlog.”

The Company will provide additional details on a quarterly conference call and webcast when it reports full financial results in May.
