Selected ReportsThree Cases of Dental Technician's Pneumoconiosis Related to Cobalt-Chromium-Molybdenum Dust Exposure: Diagnosis and Follow-up
Section snippets
Case 1
This 50-year-old man (the index case) had worked in various dental laboratories for 30 years and was a regular smoker of 20 cigarettes a day over this period. After 5 years as an apprentice in mechanical dentistry, he worked for 3 years at a storage house and 2 years as an excavator driver in a commercial sandpit. Returning to his profession in 1962, he worked almost exclusively with the manufacture of metal-framed removable partial dentures in CoCrMo alloys until 1985. For the last 13 years of
Discussion
Dental technicians are exposed to a complex mixture of dust particles defined by the type of materials involved. Sporadically, fibrotic lung disease in dental laboratories has been associated with exposure to organic dust,18, 19 but the present concept of dental technician's pneumoconiosis (DTP) is largely confined to the inorganic dust emitted in the production of metal-framed removable partial dentures based on CoCrMo alloys. Several formulas with small variations are available on the market.
