NEWS RELEASE for March 7, 2006

BIOLASE REPORTS FOURTH QUARTER AND FISCAL YEAR 2005 RESULTS

- First Positive Quarterly Cash Flow from Operations since Second Quarter 2004 -

SAN CLEMENTE, CA (March 7, 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 fourth quarter and fiscal year ended December 31, 2005.

Net revenue for the quarter ended December 31, 2005 was $19.0 million compared with $19.1 million for the fourth quarter of 2004. The gross margin for the fourth quarter of 2005 was 52 percent of net revenue as compared with 57 percent of net revenue in the same period of 2004. The operating loss for the fourth quarter of 2005 was $1.0 million versus an operating loss of $9.5 million in the same quarter of 2004. Net loss for the quarter ended December 31, 2005 was $1.2 million, or $.05 per diluted share, compared with net loss of $23.6 million, or $1.04 per diluted share, for the quarter ended December 31, 2004.

BIOLASE president and chief executive officer, Robert E. Grant, commented on the quarterly results, saying, “The Company made substantial progress during the quarter toward achieving our short-term objectives. Our manufacturing costs per unit in the fourth quarter of 2005 declined from the third quarter because of vendor component quality improvements and design changes. Our fourth quarter 2005 revenues were 63 percent higher than revenues in the third quarter. Together these two achievements helped drive our fourth quarter 2005 gross margin to 52 percent of net revenue, six basis points higher than the third quarter gross margin of 46 percent of net revenue. Additionally, the gross margin improvement and our focus on cash generation were the principal contributors to our approximate $1.1 million in cash flow from operations during the fourth quarter of 2005. This is the first time since the second quarter of 2004 that our operations generated positive cash flow. We firmly believe that our fourth quarter operating results represent a significant turnaround in our recent financial performance.”

Grant added, “In the fourth quarter of 2005, we recorded a $0.2 million compensation expense charge associated with accelerating the vesting of certain stock options. Also, we recorded one-time costs related to severance arrangements in the fourth quarter of 2005 totaling approximately $0.5 million, of which approximately $0.2 million negatively impacted gross profit and approximately $0.3 million negatively impacted general and administrative expense. We believe these fourth quarter initiatives will greatly benefit our operating margins in 2006 and beyond.”

Net revenue for the year ended December 31, 2005 was $62.0 million, an increase of 2 percent compared to net revenue of $60.7 million for the year ended December 31, 2004. The gross margin for fiscal year 2005 was 50 percent of net revenue versus 59 percent for fiscal year 2004. The comparatively lower gross margin resulted primarily from higher warranty costs, material

scrap expenses and increased fixed manufacturing infrastructure, including quality control, materials management and other support activities, while the Company continued its launch of the Waterlase MD laser system. Loss from operations was $17.0 million for fiscal year 2005 as compared to $9.4 million for 2004. Net loss for the year ended December 31, 2005 was $17.5 million, or $.76 per diluted share, compared with net loss of $23.2 million, or $1.00 per diluted share, for the year ended December 31, 2004.

Commenting on the state of the business, Grant said, “2005 was clearly a year of transition for BIOLASE. We made great strides in reducing Waterlase MD system production costs and improving product quality, which are already having a positive effect on gross margins. Also, we have been exercising more financial discipline across the organization through a reduction of operating expenses and the implementation of key cost containment measures. We finished 2005 on a strong note. Looking ahead, we are extremely optimistic about our opportunities and believe BIOLASE is well positioned for accelerating revenue growth, profits and cash generation during the course of 2006.”
