Amalgam, the most prevalent dental restoration material used in dentistry, is potentially toxic because it contains mercury. Recent international publications confirm that mercury is potentially hazardous to dental personnel, who are exposed to mercury vapors both during their work at the office and from amalgam restorations in their own oral cavities. The purpose of our study was to compare urinary mercury levels of dental personnel with a control group, and to explore possible correlations between environmental factors in the dental office and the urinary level of the personnel. Our results indicate that the urinary mercury levels of the tested dental professionals were significantly higher than those of the control group (2.39 +/- 0.319 vs. 0.899 +/- 0.34 micrograms mercury/g creatinine). Of the dental personnel examined, 72% had detectable levels of urinary mercury, compared to 27% of the control group. Although mercury levels in all participants did not exceed the toxic limit, the above findings clearly point to the need for a continuation of this survey.
汞合金是牙科领域使用最为普遍的牙齿修复材料，但因其含有汞，具有潜在毒性。近期国际出版物证实，汞对牙科工作人员具有潜在危害，他们在诊所工作期间以及自身口腔内的汞合金修复体都会使其接触到汞蒸气。我们研究的目的是比较牙科工作人员与对照组的尿汞水平，并探讨牙科诊所环境因素与工作人员尿汞水平之间可能存在的相关性。我们的结果表明，受试牙科专业人员的尿汞水平显著高于对照组（分别为2.39±0.319与0.899±0.34微克汞/克肌酐）。在接受检查的牙科工作人员中，72%的人尿汞水平可检测到，而对照组这一比例为27%。尽管所有参与者的汞水平均未超过毒性限值，但上述发现明确表明有必要继续开展此项调查。
