Profile: Henry Schein-Dentina GmbH specializes in the areas of endodontics, oral surgery, orthodontics and periodontics. Our extensive line of dental, medical and pharmaceutical products, combined with our equipment sales and service, makes us a complete medical company. Our dental's oralCDx is a brush biopsy used to assist in oral cancer detection, especially in benign-appearing lesions. This chair-side test is simple to perform, takes only a few minutes and takes the guesswork out of the oral examination.
