Dentsply Sirona is an American dental equipment manufacturer and dental consumables producer that markets its products in over 120 countries. It has factories in 21 countries. The present company is largely the result of a merger in 1993 in which Gendex Corporation acquired Dentsply International Inc. for $590 million. As an equipment maker, it designs and manufactures laboratory and specialty products relating to dental supplies. With regards to consumable products, it specializes in anesthetics, plaque and gum disease prevention and tooth polishers. It also designs and constructs artificial teeth. It has also been cited as a key player in the future-intra oral flat panel sensor market. Because of the income disparity between wealthy and developing nations, the variety of products in demand differs from region to region. On January 17, 2018, Dentsply Sirona announced the appointment of Donald M. Casey Jr., formerly CEO of the Medical Segment of Cardinal Health, as CEO and a member of the board. In 2018 a Netherlands-based certification company awarded Dentsply the “Top Employer” certification. In 2019 the company joined forces with the American Association for Dental Research to co-sponsor the Student Competition for Advancing Dental Research and its Application. The SCADA aims to bolster students research.
