title: Chronic beryllium disease in a dental laboratory technician.
abstract: Workers involved in the manufacture of dental prostheses are exposed to a number of potentially harmful substances capable of inducing lung disease. In this report, we describe a dental laboratory technician who developed chronic beryllium disease as a result of exposure in the workplace. The diagnosis of chronic beryllium disease was suspected from the clinical, radiographic, and histologic features and confirmed by the in vitro proliferation of lung lymphocytes to beryllium salts. The potential risks of beryllium use in the dental industry have been recognized for some time, but this is the first documentation of chronic beryllium disease in this population of workers. Since chronic beryllium disease may be easily confused with sarcoidosis, awareness of this occupational association is essential in preventing misdiagnosis and in providing appropriate management.
