Additional Second Quarter 2001 Highlights:

         o        The Company entered into a definitive merger agreement with
                  OrthAlliance, Inc. (NASDAQ/NM: ORAL) on May 16, 2001.
                  OrthAlliance is a leading provider of practice management and
                  consulting services to orthodontic and pediatric dentistry
                  practices in the United States. As of March 31, 2001,
                  OrthAlliance was affiliated with 226 orthodontists and
                  pediatric dentists practicing in 395 centers throughout the
                  United States. The transaction, which is subject to approval
                  by OrthAlliance stockholders and other conditions, is
                  currently anticipated to close in the third quarter of 2001
                  and to be accounted for as a purchase.

         For the second quarter of 2001, net revenue increased 24.9% to $82.2
million, compared to $65.8 million for the same quarter last year. Net income
totaled $14.8 million for the second quarter of 2001, or 25.3% above the $11.8
million in net income for the second quarter of 2000. The Company earned $0.30
per share for the second quarter of 2001, an increase of 25% over the $0.24 net
income per share for the same period in 2000. Diluted weighted average shares of
common stock outstanding for the quarter ended June 30, 2001, were 50,218,000 as
compared with 49,522,000 shares for the quarter ended June 30, 2000.

         For the six months ended June 30, 2001, net revenue increased 27.67% to
$159.7 million, compared to $125.1 million for the same period last year. Net
income totaled $28.7 million for the six months ended June 30, 2001, or 31.4%
above the $21.8 million in net income, before cumulative effect of a change in
accounting principle, for the same period last year. The Company earned $0.57
per share for the six months ended June 30, 2001, an increase of 28.7% over the
$0.44 net income per share, before cumulative effect of a change in accounting
principle, for the same period in 2000. Diluted weighted average shares of
common stock outstanding for the six months ended June 30, 2001, were
50,083,000, as compared with 49,238,000 for the six months ended June 30, 2000.

         Net income and earnings per share for the six months ended June 30,
2000 referred to above excludes the cumulative effect of a change in accounting
principle effective January 1, 2000, related to revenue recognition and Staff
Accounting Bulletin No. 101, "Revenue Recognition in Financial Statements" (SAB
101) taken in the first quarter of 2000. The cumulative effect of this change in
accounting principle, net of tax benefit, was a charge of $50.6 million ($1.01
per share) taken during the first quarter of 2000.

         Net revenue for existing centers was strong during the second quarter
of 2001. Comparable center net revenue growth during the second quarter of 2001
was 22.6%. Comparable center net revenue growth is defined as growth in net
revenue by centers affiliated with the Company throughout each of the two
periods being compared. Comparable center net revenue growth during the second
quarter of 2001, including only centers affiliated with the Company for at least
26 months, was 11.1%.

         As previously announced, OCA and OrthAlliance entered into a definitive
merger agreement on May 16, 2001, whereby a wholly-owned subsidiary of OCA would
merge into OrthAlliance in a stock-for-stock transaction, with OrthAlliance
becoming a wholly-owned subsidiary of OCA. OCA and OrthAlliance also
subsequently announced that OrthAlliance had received signed amendments to the
employment agreements and service or consulting agreements of OrthAlliance
affiliated professionals representing more than the minimum threshold amounts
specified as a condition to OCA's obligation to close the proposed merger with
OrthAlliance.

         Bart F. Palmisano, Sr. said, "We focused diligently during the second
quarter on meeting with the majority of OrthAlliance's outstanding affiliated
orthodontists and pediatric dentists, and we continue to be impressed with their
high level of professionalism and commitment to quality. We look forward to
welcoming these highly regarded and exceptionally talented professionals to our
organization."

         Bart F. Palmisano, Sr. continued, "Our proposed merger with
OrthAlliance presents an unprecedented strategic opportunity for us. Rest
assured, we intend to continue to devote substantial resources to completing
this merger and building strong relationships with OrthAlliance's affiliated
orthodontists and pediatric dentists. We are excited about our prospects for
growth and our continued ability to build shareholder value."

         During the second quarter of 2001, the Company affiliated with 2 new
orthodontic professionals, and opened 8 new centers. Of the 8 new centers
opened, all were newly developed centers.

         In closing, Bart F. Palmisano, Sr., said, "Our continued strong results
are a product of focused, intelligent growth, which has long been our operating
philosophy. While patient case starts increased 23.3% over the second quarter of
2000, the dollar amount of those new patient contracts increased by more than
27.3%. We are extremely encouraged about all our growth initiatives and remain
confident in our ability to execute our operating strategy soundly. The business
discipline that we have exercised to date will continue to serve us well going
forward in building long-term shareholder value."
