     National Dentex Corporation Announces First Quarter Results

    WAYLAND, Mass.--(BUSINESS WIRE)--May 2, 2007--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, 2007. For the quarter, the
Company reported $43,343,000 in sales with net income of $2,244,000,
or $.40 per share on a diluted basis. Sales for the same quarter of
the prior fiscal year were $36,789,000 and net income was $2,149,000
or $.38 per share on a diluted basis.

    David Brown, President and CEO, commented: "Coming off a very
challenging 2006 we are pleased with our start to 2007. Our financial
performance this past quarter, particularly in gross profit margin
improvement, we believe reflects some early returns on our recent
efforts to better leverage labor requirements with new technology. We
plan on continuing our ongoing efforts to reevaluate and optimize our
mix of labor and technology and thereby further improve our financial
performance throughout 2007. In this regard, we are focusing attention
on operational initiatives at all of our laboratories, seeking to
further improve execution throughout our system, and ensuring that our
entire organization consistently anticipates, meets, and exceeds our
clients' needs and expectations. Our acquisition program will continue
to search out opportunities to add laboratories to our family of
existing laboratories that are capable and committed to providing this
enhanced level of client service."
