Exhibit 99.1

                     National Dentex Corporation Announces
                 Sales and Earnings for the Third Quarter 2006



    WAYLAND, Mass.--(BUSINESS WIRE)--Nov. 6, 2006--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, 2006. Sales for the
quarter totaled $34,613,000 compared with $33,343,000 a year earlier,
an increase of 3.8%. Net income for the quarter was $925,000 or $.16
per share on a diluted basis, decreasing from $1,379,000 or $.25 per
share on a diluted basis in 2005.

    For the nine months ended September 30, 2006, sales were
$109,518,000 compared to $101,504,000 for the same period in 2005, an
increase of 7.9%. Sales during the nine month period increased 4.4%
from 2005 on a same laboratory basis. Net income for the nine month
period of $5,394,000 or $.94 per diluted share was down from
$5,745,000 or $1.03 per share on a diluted basis in 2005.

    David Brown, President and CEO stated: "We were disappointed by
our third quarter results but are somewhat more optimistic going
forward about the near-term economic outlook now that energy and
commodity costs seem to be stabilizing. Sales during the quarter grew
at a measured but modest rate during a period in which we experienced
increased material and operating expenses, negatively impacting our
margins. Our materials costs, particularly precious metals and other
energy-related operating costs, reached relatively high historical
rates this year and have continued at or near those levels, with some
leveling off noticeable more recently. The modest sales growth and
increased cost pressures we have been experiencing have come at a time
in which competitive pricing pressures from other laboratories
operating or entering our marketplaces, including offshore facilities
in China and elsewhere, have made it more difficult for us and others
in our industry to raise prices. We continue to monitor competitive
trends in the industry and we continue to review our pricing options
by laboratory and product line as we consider the remainder of the
year and plan ahead for 2007."

    Mr. Brown continued, "Despite the challenging environment, we
continue to invest in and expand our CAD-CAM production capabilities
with a goal of being able to service all of our existing laboratories
for this product line out of an efficient, central processing facility
located in Manchester, New Hampshire. While in the short-term this
continued CAD-CAM investment has added additional expense pressures,
we continue to believe that we will be able to realize long-term
benefits in the future as we refocus and redeploy our labor resources
throughout our laboratories and process more units on a more
cost-effective basis."

    Mr. Brown concluded, "We are also excited and very pleased to have
completed and announced the acquisitions of the Keller Group and
Impact Dental subsequent to the end of our third quarter in early
October bringing to the Company, based on their last fiscal years
ended December 31, 2005, in excess of $20,500,000 of annualized sales.
Keller, our largest acquisition to date, and Impact, our first venture
into Canada, both promise to bring many opportunities to our family of
laboratories. We look forward to working with and utilizing the
talents of their outstanding laboratories to help further improve our
operations and further enhance our position in the marketplace."
