Reclassifications - Certain amounts in prior year financial statements have been
reclassified to conform with the presentation used in 1999.


2.     Comprehensive Income (Loss)

Total comprehensive income (loss), net of the related estimated tax, was
$(76,617) and $1,001,204 for the three months ended June 30, 1999 and 1998,
respectively, and $52,059 and $1,841,868 for the six months ended June 30, 1999
and 1998, respectively.


3.     Segment Reporting

The Company adopted SFAS No. 131, Disclosures about Segments of an Enterprise
and Related Information, for the year ended December 31, 1998. SFAS No. 131
established standards for reporting information about operating segments in
annual financial statements and requires selected information about operating
segments in interim financial reports issued to stockholders. It also
established standards for related disclosures about products and services, and
geographic areas. Operating segments are defined as components of the enterprise
about which separate financial information is available that is evaluated
regularly by the chief operating decision maker, or decision making group, in
deciding how to allocate resources and in assessing performance.

The Company develops, manufactures, markets and sells high technology dental
products, such as air abrasive equipment, lasers, curing lights and intra oral
cameras. The Company sells these products to national and regional dental
distributors in its four fundamental business segments: North America, Japan,
Europe and Other International. The reportable segments are managed separately
because selling techniques and market environments differ from country to
country. The remaining activities of the Company, which are reported as "Other",
include industrial, parts and accessories and royalty income.

The accounting policies of the business segments are consistent with those
described in Note 1. The Company's Chief Operating Decision Maker evaluates
segmental performance and allocates resources based on operational earnings
(gross profit less selling and marketing expenses).

4.     Litigation

On December 20, 1996, American Dental filed a lawsuit against Kreativ, Inc.
("Kreativ") and two individuals in the United States District Court for the
Eastern District of Michigan, Southern Division. In February 1999, the Company
was awarded $635,203 in damages, plus attorney fees and interest. On August 2,
1999, the Company settled the judgment it had been awarded against Kreativ by
the Federal District Court in Michigan for false advertising violations of the
Lanham Act. Kreativ paid the Company $582,500 in settlement of the previously
awarded judgment which was recorded by the Company in August of 1999.

On July 7, 1997 and May 5, 1998, the Company filed lawsuits against Kreativ in
the United States District Court for the Southern District of Texas alleging
infringement of U.S. Patents. These claims were dismissed and the Company
appealed the dismissal. On June 10, 1999, the Company reached a settlement with
Kreativ on the two lawsuits the Company had filed against Kreativ alleging
patent infringement and which were on appeal. Kreativ paid the Company $300,000
and was granted a paid up license under the patents-in-suit. The Company
recorded this royalty during the three month period ended June 30, 1999.

The Company is not currently involved in any litigation.

Notes to Condensed Consolidated Financial Statements
June 30, 1999 (Unaudited)

5.       Restatement

The Company has restated its previously reported net income for the three and
six month periods ended June 30, 1999 for the correction of an error. The effect
of the correction was to reduce net income by approximately $430,000 for the
three and six month periods ended June 30, 1999 or $0.05 and 0.06 per share for
the respective periods.

ITEM 2.         Management's Discussion and Analysis of Financial Condition
                and Results of Operations

Forward Looking Statements

       The following discussion and analysis contains statements which are
"forward looking statements" within the meaning of the Securities Exchange Act
of 1934, as amended, and are subject to uncertainties. Such uncertainties
include, without limitation, the potential lack of product acceptance, the
potential failure of distributors to meet purchase commitments, the potential
loss of distributor relationships, the potential failure to receive or maintain
necessary regulatory approvals, the extent to which competition may negatively
affect prices and sales volumes or necessitate increased sales expenses, and any
other uncertainties described in the discussion below.

Results of Operations

       For the three month period ended June 30, 1999, the Company earned
$36,870 compared to $1,002,397 in the same period in 1998. For the six month
period ended June 30, 1999, the Company earned $165,546 compared to $1,843,061
for the same period in 1998. Net income in 1999 includes recognition of income
tax expense of $131,282 and $307,182 for the three and six month periods ended
June 30, 1999, respectively. In 1998, the Company offset current income tax
expense with a deferred income tax benefit related to net operating loss
carryforwards that were previously reserved.

       The Company had revenues of $6,568,805 for the three month period ended
June 30, 1999 as compared to $6,396,913 for the same period in 1998. The Company
had revenues of $12,985,559 for the six month period ended June 30, 1999 as
compared to $12,104,580 for the same period in 1998. The increases in revenues
are due to a strong increase in international sales, partially offset by a
decline in North American sales. The decline in North American sales is
primarily attributable to the liquidation of dealer inventories. An overall
increase in revenues for 1999 will be primarily dependent on a return of higher
air abrasion sales after the liquidation of dealer inventories. Management is
actively working to liquidate dealer inventories in North America and stimulate
air abrasion sales.

       Royalty income increased $288,463 for the three month period ending June
30, 1999, compared to the same period in 1998. Royalty income increased $521,307
for the six month period ending June 30, 1999 as compared to the same period in
1998. These increases are due to the licensing agreement with ESC Medical
Systems, Ltd. recorded in the first quarter of 1999 and the settlement of
$300,000 from Kreativ, Inc. regarding patent litigation recorded during the
second quarter of 1999.

       Gross profit as a percentage of revenues was 46% and 50% for the three
and six month periods ended June 30, 1999 compared to 58% and 56% for the same
periods in 1998. The gross profit decline during 1999 compared to 1998 is
primarily attributable to sales in 1999 of camera systems which generally have
lower gross margins than the other products of the Company.

       Selling, general and administrative expenses increased $106,334 or 4% and
$828,352 or 18% for the three and six month periods ended June 30, 1999 compared
to the same periods in 1998. These increases are primarily due to increased
selling, marketing, and general and administrative expenses related to the
camera business acquired from Dental Vision Direct ("DVD") in August 1998 and
amortization of goodwill also related to the camera business. Management expects
sales and marketing costs to return to historical norms in the second half of
the year.

       Interest expense increased by $85,974 and $169,168 for the three and six
month periods ended June 30, 1999. The increase during 1999 is primarily due to
increased borrowings on the Company's revolving line of credit which was
primarily used to fund the acquisition of the camera business.

Liquidity and Capital Resources

       The Company's operating activities provided $1,248,686 in cash resources
during the six month period ended June 30, 1999. The cash provided by operations
in 1999 was primarily due to net income of $165,546, decreases in accounts
receivable of $337,333, inventories of $682,803, notes receivable of $180,000
and $1,127,300 of non-cash expenses including depreciation, amortization and
deferred taxes. Cash provided by operating activities was reduced primarily by
decreases in accounts payable of $181,044, compensation and employee benefits of
$141,903, other non-current liabilities of $756,702.

       The Company's investing activities used $656,676 in cash resources during
the six month period ended June 30, 1999. The cash used in investing activities
in 1999 related primarily to the expansion of the manufacturing facility in
Corpus Christi, Texas.

       The Company's financing activities used $757,097 in cash resources during
the six month period ended June 30, 1999. The cash used in financing activities
was primarily used to reduce borrowings on the Company's revolving line of
credit.

       The Company has a $7,500,000 revolving line of credit from a bank, with
interest at prime or the LIBOR rate (Eurodollar rates, which were approximately
5% at June 30, 1999) plus 1.5%, which is due in September 2000. The Company's
borrowing is secured by a pledge of the Company's accounts receivable,
inventory, equipment, instruments, patents, copyrights and trademarks. As of
June 30, 1999, the Company had $5,150,000 outstanding and $2,350,000 available
under this line of credit.

       The Company believes, based upon its current business plan, that current
cash, available financing resources and cash generated through operations should
be sufficient to meet the Company's anticipated short term and long term
liquidity needs for the foreseeable future.

Year 2000 Issue

       The Year 2000 issue is the result of computer programs being written
using two digits rather than four to define the applicable year. The Company
established a team that has completed an awareness program and assessment
project to address the Year 2000 issue including information technology (IT) and
non-IT systems. The Company determined that it will be required to upgrade or
replace portions of its software so that its computer and phone systems will
properly utilize dates beyond December 31, 1999 and that certain non-IT systems,
such as alarms, equipment, and heating and cooling systems may need to be
upgraded or replaced. In April 1999, the Company upgraded its business software
and believes that it is Year 2000 compliant. The Company expects to be able to
complete the remaining Year 2000 remediation by the end of the August 1999 and
believes that all of its systems will then be Year 2000 compliant. If such
planned remediation cannot be completed prior to the end of 1999, the Year 2000
issue could cause production interruptions that could have a material impact on
the operations of the Company. Anticipated spending for Year 2000 remediation,
expected to cost approximately $50,000, will be expensed as incurred and is not
expected to have a significant impact on the Company's ongoing results of
operations. Through June 30, 1999, the Company incurred approximately $40,000
attributable to Year 2000 remediation.

       The Company has initiated communications with a substantial majority of
its significant suppliers and large customers to determine their plans to
address the Year 2000 issue. While the Company expects a successful resolution
of all issues, there can be no guarantee that the systems of other companies
will be converted in a timely manner, or that a failure to convert by a supplier
or customer would not have a material adverse effect on the Company. The Company
considers the failure of a supplier or customer to be Year 2000 compliant to be
the most reasonably likely worst case scenario, since it expects to be Year 2000
compliant prior to the end of August 1999 and has determined it has no material
exposure to contingencies related to the Year 2000 issue for the products it has
sold. The Company has substantially completed its contingency plan after
assessing which third parties are most likely to have an adverse effect on the
Company and continues to review potential exposure. The plan is expected to be
complete by the end of 1999. Some material adverse effect could result despite
such contingency planning.

                                       11
<PAGE>   12

       The costs of the project and the date by which the Company plans to
complete the Year 2000 upgrades are based on management's best estimates, which
were derived utilizing third party plans and other factors. However, there can
be no guarantee that these estimates will be achieved and actual results could
differ materially from those plans. Specific factors that might cause such
material differences include, but are not limited to, the compatibility of the
upgrades and conversions, availability of personnel to correct capability issues
and similar uncertainties. The disclosure in this section contains information
regarding Year 2000 readiness which constitutes "Year 2000 Readiness Disclosure"
as defined in the Year 2000 Readiness Disclosure Act.
