          National Dentex Corporation Announces First Quarter Results

     WAYLAND, Mass.--(BUSINESS WIRE)--April 28, 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 first
quarter ended March 31, 2004. For the quarter, the Company reported $27,928,000
in sales with net income of $1,705,000 or $.48 per share on a diluted basis.
Sales for the same quarter of the prior fiscal year were $23,965,000 with net
income of $1,332,000 or $.39 per share on a diluted basis.
     David Brown, President and CEO, commented: "We are encouraged by the
improved results of the first quarter of 2004. Not only have the laboratories we
acquired in 2003 been integrated into our system, but our internal sales have
stabilized and begun to grow. This combination produced a 16% increase in sales
versus the first quarter of 2003. This growth, coupled with our continued
emphasis on cost containment, particularly labor and related benefits, resulted
in a 28% increase in net income. These results and our improved operating
margins reflect the leverage that increased sales through the Reliance(TM)
program can bring to the Company. We believe that as the economic conditions
continue to improve, our laboratories, with their proven ability to deliver
outstanding service, superior quality and prompt delivery will continue to build
on that leverage.
     "We did not close on any acquisitions in the quarter but have continued to
actively pursue potential candidates. We expect that the discussions we recently
have had, as well as new ones just begun, will eventually result in the addition
of more quality dental laboratories to our expanding network.
     "We will continue our efforts in the balance of 2004 with the same energy
and attention as exerted in the first quarter. In the face of the past industry
slowdown, we worked diligently at coordinating our internal focus on
efficiencies while expanding our external presence through the Reliance(TM)
program. We continue to believe that through these efforts we have distinguished
ourselves as a true value-added resource to our dentist partners. As these
relationships continue to take hold and expand, we remain committed to utilizing
them to build a sustained and profitable growth for National Dentex and its
shareholders."
