Mercury levels in blood and in mouth air before and after chewing were measured in 47 persons with and 14 persons without dental amalgam restorations. Questionnaires relating to exogenous sources of mercury exposure were administered to both groups. Differences in the mouth air mercury levels before and after chewing were statistically significant in the group with amalgams, but not in the group without amalgams. Analysis of the data from the questionnaires indicated that little or no exogenous exposure to mercury occurred among the two groups. Blood mercury concentrations were positively correlated with the number and surface area of amalgam restorations and were significantly lower in the group without dental amalgams.
对47名有牙科汞合金修复体的人和14名没有牙科汞合金修复体的人，测量了咀嚼前后血液和口腔空气中的汞含量。两组都进行了与汞暴露外源相关的问卷调查。有汞合金修复体组咀嚼前后口腔空气中汞含量的差异具有统计学意义，而无汞合金修复体组则无此差异。问卷调查数据分析表明，两组外源汞暴露很少或几乎没有。血汞浓度与汞合金修复体的数量和表面积呈正相关，且无牙科汞合金修复体组的血汞浓度显著更低。
