Lai gan jautājums ir strīdīgs par to cik liels dzīvsudraba daudzums organismā ir patiešām kaitīgs, pētījumi parāda, ka nelielos daudzumos tas tomēr nonāk pacienta organismā pat tikai plobmbju lietošanas procesā – ir paaugstināts dzīvsudraba daudzums matos, asinīs, urīnā. Saskaņā ar pētījumiem tas var kaitēt dažiem cilvēkiem vairāk nekā citiem.

Abstract: .... Two key studies known as the Children’s Amalgam Trials are widely cited as evidence of safety. However, four recent reanalyses of one of these trials now suggest harm, particularly to boys with common genetic variants. These and other studies suggest that
susceptibility to mercury toxicity differs among individuals based on multiple genes, not all of which have been identified. These studies further suggest that the levels of exposure to mercury vapor from dental amalgams may be unsafe for certain subpopulations. Moreover, a simple comparison of typical exposures versus regulatory safety standards suggests that many people receive unsafe exposures. Chronic mercury toxicity is especially insidious because symptoms are variable and nonspecific, diagnostic tests are often misunderstood, and treatments are speculative at best. Throughout the world, efforts are underway to phase down or eliminate the use of mercury dental amalgam.

Ja dzīvsudrabs nenonāk pacienta organismā, tad pasakiet kā dzīvsudraba daudzums matos korelē (ir sakarība) amalgama plombju skaitam???

The hair mercury content increased significantly with the number of dental amalgam fillings, explaining partially the higher levels in the mothers …..--------------------------------------
Atkal pētījums par to, ka dzīvsudraba saturs urīnā augstāks tiem, kuriem ir plombas.

RESULTS:
Urinary mercury levels were statistically significantly higher in participants with amalgam surfaces, with an average difference of 0.55 μg/g-creatinine. Per amalgam surface, we estimated an expected increase of 0.04 μg/g-creatinine. Measured urinary mercury levels were also statistically significantly higher in participants with dental amalgam surfaces following the oral administration of 2,3-dimercaptopropane-l-sulfonate (DMPS) and meso-2,3-dimercaptosuccinic acid (DMSA) which are used to mobilize mercury from the blood and tissues.

CONCLUSIONS:
Our findings suggest that mercury exposure from amalgam fillings adversely impact health and therefore are a health risk. The use of safer alternative materials for dental fillings should be encouraged to avoid the increased risk of health deterioration associated with unnecessary exposure to mercury.

Conclusions The long-term presence of dental amalgam (at least 5 years) did not result in any remarkable changes in the levels of mercury and tin in the pulp tissue; however,
there were increases in the level of mercury in the blood circulation even five years following the placement of the restoration.

Five hundred and seven children, 8-12 yr of age at baseline, participated in a clinical trial to evaluate the neurobehavioral effects of Hg from dental amalgam tooth fillings. ………..

These findings suggest increased susceptibility to the adverse neurobehavioral effects of Hg among children with common genetic variants of COMT, and may have important implications for strategies aimed at protecting children from the potential health risks associated with Hg exposure.

Te eksperimenti ar laboratorijas žurkām – korelācija starp „amalgamu” un mutes audu bojājumiem pēcnācējiem. Pētnieki gan arī attiecina to uz clivēkiem iesaka jaunajām māmiņām atturēties no amalgāma ielikšanas vai izņemšanas mazuļa gaidīšanas laikā.

CONCLUSIONS: There is a positive correlation between blood mercury levels and oral tissue response in mothers, however, the negative impact of mercury on oral tissues of offspring rats was due to high mercury levels in their mothers' blood during pregnancy.
We would recommend that women should - as far as possible - postpone having dental amalgam filling placed or removed during pregnancy to avoid its harmful effect on the foetus. Further clinical studies are recommended to test our findings in man.

The results of our study suggest that dental amalgams contribute to ongoing kidney damage at the level of the PTs in a dose-dependent fashion.

Our data provide evidence that low exposure to Hg from dental amalgam fillings exerts an effect on kidney tubular functions in children.
