Dental amalgams, 228 table

Total mercury concentrations in breast milk from other countries and exposure scenarios were 3.6 2.2 ppb for an urban population in Tokyo, Japan (Fujita and Takabatake 1977), 0.6 0.4 ppb for Swedish women that were fish consumers with 12 dental amalgams (Oskarsson et al. 1996), 0.2-6.3 ppb (range) for Swedish women that consumed fish (SkerfVing 1988), and 9.5 5.5 ppb for an urban population of women in Madrid, Spain (Baluja et al. 1982) (Table 5-17). Some of the highest levels were reported in fish eaters, and about 20% of the total mercury content of the milk was methylmercury. The median and... 

Diagnosis is by estimation of blood and urine mercury concentrations (Table 1). Long-term monitoring of exposure, such as may be necessary with those working with dental amalgam, may be carried out using hair or nail clippings. 

The MGC test confirmed the quasi-perfect cytocompatibility of the of Pd, Au, Ti powders and of alloys containing respectively these metals, since the number of MGC in exposed cultures was identical to that in control cultures (Table 5.4 Figures 5.3 and 5.4). However, cultures exposed to pure Ni, Co, Ag and to Ni-rich alloys and dental amalgams developed eight- to ten-fold increases of MGC with respect to control cultures (Table 5.4 Figures 5.3 and 5.5). The inflammatory effect of silver is confirmed in the Ag32Pd57 alloy. Stainless steel without a major influence on cell viability induces inflammatory reactions comparable to those produced by Cr. 

Table 16.2 [31] summarizes the exposure of a hypothetical average person to the three principal forms of mercury. The largest numbers are associated with dental amalgam and the eating of fish. While estimates of the intake of mercury vapor from dental fillings show rather extreme variations [31,32], they are said to account for90-99%...
