Three cases of dental technician's pneumoconiosis related to cobalt-chromium-molybdenum dust exposure

Abstract

Dental technician's pneumoconiosis (DTP) is a rather recent finding in subjects exposed to the dust generated in dental laboratories producing metal-framed removable partial dentures from alloys based on cobalt, chromium, and molybdenum. This study presents details of the first three Swedish cases of DTP with some emphasis on the diagnostic procedures and the dust exposure. A follow-up of at least 5 years from diagnosis is included.
