Urinary mercury levels were determined in 22 dentists and 46 dental nurses and assistants working in 15 private dental offices in West-Germany. For comparison, urinary mercury levels of 29 subjects without occupational mercury exposure were studied. On average, urinary mercury in dental personnel was higher than in the reference group. Individual mercury levels, however, were all significantly below present occupational exposure limits. Urinary mercury was significantly correlated with the number of amalgam fillings in dental personnel as well as in the reference group. Following administration of Dimaval a significant increase of mercury excretion was observed in both groups. Regarding total exposure to mercury in dental personnel, the contribution of mercury exposure from the occupational environment is of the same order of magnitude as their exposure from their own amalgam fillings. Dental nurses were found to be more exposed than dentists. This finding seems to be related predominantly to the larger number of amalgam fillings in dental nurses.
对在西德15家私人牙科诊所工作的22名牙医以及46名牙科护士和助手测定了尿汞水平。为作比较，研究了29名无职业汞接触的受试者的尿汞水平。牙科工作人员的尿汞平均水平高于参照组。然而，个体汞水平均显著低于目前的职业接触限值。牙科工作人员以及参照组的尿汞与汞合金补牙数显著相关。给予二巯丙醇后，两组均观察到汞排泄显著增加。就牙科工作人员的汞总接触而言，职业环境汞接触的贡献与他们自身汞合金补牙的接触处于同一数量级。发现牙科护士比牙医接触更多汞。这一发现似乎主要与牙科护士补牙数较多有关。
