     National Dentex Corporation Announces Sales and Earnings for
                        the Third Quarter 2007

    WAYLAND, Mass.--(BUSINESS WIRE)--Nov. 5, 2007--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, 2007. Sales for the
quarter totaled $41,204,000, compared with $34,613,000 for the third
quarter of 2006, an increase of 19.0%. Net income for the quarter was
$1,308,000 or $.23 per share on a diluted basis, increasing from
$925,000 or $.16 per share on a diluted basis in 2006.

    For the nine months ended September 30, 2007, sales were
$128,981,000 compared to $109,518,000 for the same period in 2006, an
increase of 17.8%. Net income for the nine month period increased to
$5,970,000 or $1.05 per diluted share from $5,394,000 or $.94 per
share on a diluted basis in 2006.

    David Brown, President and CEO stated: "Sales growth of 17.8% in
the nine months ended September 30, 2007, and 19.0% for the third
quarter, continues to be driven by our 2006 late year acquisitions.
Internal sales, meaning sales at laboratories owned over one year,
were down 1.2% for the nine months, but down only 0.9% for the
quarter, or $305,000. We have been focusing throughout the year on
leveraging our labor and benefit costs, our major expense component,
by implementing new technology and undertaking other measures to
enhance productivity and are starting to see very favorable results in
doing so. While our internal sales for the most recent quarter were
down $305,000, our labor and benefit costs for the same period and for
those same laboratories were down $1,121,000. As a result, third
quarter operating income increased $1,111,000 or 57.7% and net income
increased $383,000 or 41.4% over the same quarter in 2006."

    Mr. Brown concluded, "In addition to this focus on internal
operations we remain committed to our acquisition strategy and will
continue to search out opportunities to add laboratories which will
enhance our position as the leading operator of high quality dental
laboratories in the United States."
