        National Dentex Corporation Announces Third Quarter 2004 Results

     WAYLAND, Mass.--(BUSINESS WIRE)--Oct. 29, 2004--National Dentex Corporation
(NASDAQ: NADX), one of the largest owner/operators of dental laboratories in the
United States, today announced its results for the third quarter ended September
30, 2004. Sales for the quarter totaled $27,395,000 compared with $24,358,000 a
year earlier. Net income for the quarter was $980,000 or $.27 per share on a
diluted basis compared to $1,277,000 or $.37 per share on a diluted basis in
2003.
     For the nine months ended September 30, 2004, sales were $84,154,000
compared to $73,505,000 for the same period in 2003. Net income was $4,742,000
or $1.31 per share on a diluted basis compared to $4,259,000 or $1.23 per share
on a diluted basis for the comparable period of 2003.
     David L. Brown, President and CEO, stated: "Sales, while up 12.5% in the
current quarter, were below our expectations. Following the recent hurricanes
throughout the southeastern United States, our laboratories in those areas lost
a combined total of 24 operating days due to their closure for various amounts
of time. We did pay our employees during this difficult time and appreciate
their efforts and support they give us on a day to day basis. Additionally, as
one would expect, the amount of dentistry being done in those areas affected
slowed down during the period after the storms. We are now seeing a return to
normalcy at the laboratories that were involved. Fortunately we were spared any
additional costs since no major physical damage was incurred at any of our
locations as a result of those storms.
     Mr. Brown further added: "In addition, we incurred expenses related to
compliance requirements with the Sarbanes-Oxley Act, specifically as it relates
to Section 404. Due to our structure of 40 locations spread across the country,
the levels of testing and documentation needed to satisfy these new requirements
will result in higher expenditures than if operations were concentrated in a
single or only a few locations. During the third quarter we expended
approximately $360,000 on this project. While we anticipate a similar level of
expense during the fourth quarter, we do not believe this level of financial
commitment will be required in subsequent years since we believe most of this
expense relates to the initial cost of documenting and testing these controls.
In the meantime we will continue our efforts to support and strengthen our
commitment to good corporate governance and the interests of our shareholders.
     Mr. Brown continued: "On the positive side, in August we announced the
acquisition of D. H. Baker Dental Laboratory, of Traverse City, Michigan. D. H.
Baker had sales in excess of $4,000,000 in their last fiscal year ended December
31, 2003. We are pleased to add Doug Baker and his team to our family of
laboratories and look forward to contributions, both financially and technically
from them. We continue to have discussions with a number of potential
acquisition candidates. We remain firmly committed to our acquisition program
and its potential to create value for shareholders."
