Segment Reporting Disclosure [Text Block] | NOTE 9 — SEGMENT AND GEOGRAPHIC DATA Operating segments are reported in a manner consistent with the internal reporting provided to the chief operating decision maker. The chief operating decision maker, who is responsible for allocating resources and assessing performance of the operating segments, has been identified as the Chief Executive Officer (the “CODM”). The Company conducts its business through two reportable segments: Dental and Medical. These segments offer different products and services to different customer base. The CODM assesses the financial performance of the segment and decides how to allocate resources based on Product sales, net, and Operating income (loss). The Company provides general corporate services to its segments; however, these services are not considered when making operating decisions and assessing segment performance. These services are reported under “Corporate Services” below and these include costs associated with executive management, investor relations, patents, trademarks, licensing agreements, new instruments developments, financing activities and public company compliance. The following tables present information about our reportable and operating segments for the three months ended March 31, 2025, and 2024:
