            National Dentex Corporation Announces Sales and Earnings
                           for the Third Quarter 2005

    WAYLAND, Mass.--(BUSINESS WIRE)--Oct. 28, 2005--National Dentex
Corporation (NASDAQ: NADX), one of the largest owner/operators of
dental laboratories in the United States, today announced sales and
earnings for the third quarter ended September 30, 2005. Sales for the
quarter totaled $33,343,000 compared with $27,395,000 a year earlier,
an increase of 21.7%. Net income for the quarter was $1,379,000 or
$.25 per share on a diluted basis, an increase of 47.5% versus
$935,000 or $.17 per share on a diluted basis in 2004.
    For the nine months ended September 30, 2005, sales were
$101,504,000 compared to $84,154,000 for the same period in 2004, an
increase of 20.6%. Net income increased 26.6%, to $5,745,000 or $1.03
per diluted share from $4,538,000 or $.83 per share on a diluted basis
in 2004.
    David Brown, President and CEO stated: "Operationally, I am
pleased to report that we experienced significant margin improvements
in the third quarter with respect to gross profit and operating
income. Our price adjustments earlier in the year and our focus on
improving internal efficiencies through technical training and
management development programs helped us achieve these positive
results. Together with the promising performance from our recent
acquisitions, these operational efforts have helped to offset the cost
pressures we continue to incur in an extremely challenging economic
environment, which have been aggravated by increases in our costs for
providing employee benefits and complying with new and more
comprehensive securities and accounting regulatory requirements. We
plan on continuing to focus on improving our internal efficiencies and
containing our costs of doing business. We believe that this focus on
cost containment will allow us to better leverage future sales growth
to more profitably operate our growing network of laboratories."
