Dental laboratory technicians may be exposed to a number of toxic materials including metal alloys that have been identified as potential health hazards. Particularly, alloys, such as vitallium, wisil, duralium and vironite which in dentistry are used in the production of crowns, bridges and dental prostheses. The most common constituents of these prostheses are cobalt (45-70%), chromium (25-30%), molybdenum, silica, nickle, tantalum and other metals in different amounts. The objectives of this paper are to describe the technology related to the production of dental prostheses, evaluating the most hazardous working jobs and reporting results concerning the monitoring of cobalt and chromium in the urine of 31 people employed in five laboratories of Bergamo, Italy, where workplace air monitoring has also been undertaken.
牙科实验室技术人员可能会接触到多种有毒物质，包括已被确定为潜在健康危害的金属合金。特别是维它灵、维西尔、硬铝和铁镍合金等合金，在牙科领域用于制作牙冠、牙桥和假牙。这些假牙最常见的成分是钴（45 - 70%）、铬（25 - 30%）、钼、二氧化硅、镍、钽以及其他含量各异的金属。本文的目的是描述与假牙生产相关的技术，评估最具危险性的工作岗位，并报告对意大利贝加莫五个实验室的31名员工尿液中钴和铬的监测结果，同时也进行了工作场所空气监测。
