“…Saliva has been used to assess mercury release from amalgam fillings for adults with complaints self -related to amalgam ( Lygre et al, 1999 ). The median of mercury concentration in saliva was 9.5 g /l and therewith far beyond the findings of the present study.…”

Mercury levels measured in urine, hair, and saliva of 245 German children ( 8 -10 years old ) are reported. Mercury concentrations in urine ranged between < 0.1 and 5.3 g / l [ geometric mean ( GM ) 0.26 g / l or 0.25 g / g creatinine; median for both, 0.22 in g / l and g / g, respectively ]. Using multiple linear regression analysis, two predictors have been found accounting for 25.3% of the variance of mercury levels in urine: the number of teeth with amalgam fillings ( 23.2% ) and the number of defective amalgam fillings ( 2.1% ). The mercury content in hair ranged from < 0.06 to 1.7 g / g ( GM 0.18 g / g; median 0.18 g / g ). The frequency of fish consumption, the smoking habits of the parents, and the age of the children accounted for 20.4% of the variance of mercury levels in hair. The correlation between the hair mercury content and urine mercury concentration was low ( r = 0.297 ). Mercury levels in saliva ranged between < 0.32 and 4.5 g / l ( median 0.16 g / l ). The mercury concentration in saliva was below the limit of quantification of 0.32 g / l in more than 70% of the samples. Mercury analysis in urine is suitable to estimate mercury exposure due to amalgam fillings, whereas hair mercury better reflects mercury intake by fish consumption. Up to now, saliva does not seem to be a suitable tool to monitor the mercury burden, at least not at low exposure levels.

“…The slow release of Hg from amalgams is known to select for Hg-resistant bacteria in the gut [59]. Ag is also released [42] and Ag-resistant oral bacteria were recently reported [14]. Furthermore, it appears that Ag release from Wlm processing, mining sites, and dental amalgams are large sources of Ag in human wastewaters where selection for Ag resistance might also occur (e.g.…”

Silver products have been used for thousands of years for their beneficial effects, often for hygiene and in more recent years as antimicrobials on wounds from burns, trauma, and diabetic ulcers. Silver sulfadiazine creams (Silvazine and Flamazine) are topical ointments that are marketed globally. In recent years, a range of wound dressings with slow-release Ag compounds have been introduced, including Acticoat, Actisorb Silver, Silverlon, and others. While these are generally accepted as useful for control of bacterial infections (and also against fungi and viruses), key issues remain, including importantly the relative efficacy of different silver products for wound and burn uses and the existence of microbes that are resistant to Ag+. These are beneficial products needing further study, although each has drawbacks. The genes (and proteins) involved in bacterial resistance to Ag have been defined and studied in recent years.

“…Others have shown that a considerable part of the Hg in saliva is present as amalgam particles [18], and that Hg levels in saliva do not correlate with concentrations in blood and urine [19].…”

“…Because Hg in saliva can vary depending on the presence of dental amalgams containing the element [18], two individuals were tested: one with dental amalgams and one without. Mercury concentrations for the saliva controls (before chewing) were 30.6 AE 2.3 ng mL À1 and 1.5 AE 0.5 ng mL À1 for the individual with and without dental amalgams, respectively.…”
