TLDR
Analysis of the data from the questionnaires indicated that little or no exogenous exposure to mercury occurred among the two groups.Abstract:
Mercury levels in blood and in mouth air before and after chewing were measured in 47 persons with ana 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.read more

Mercury Exposure and Public Health
TL;DR: Mercury has a long and interesting history deriving from its use in medicine and industry, with the resultant toxicity produced, and the disproved relationship between vaccines and autism related to the presence of the mercury-containing preservative, thimerosal.

Metal release from dental biomaterials.
TL;DR: Examination of corrosion products released from dental alloys in natural or synthetic saliva indicate that mercury released from amalgams could be a substantial part of man's daily intake of this element, e.g. in the initial period following insertion, as well as on a long-term basis.

Intra-oral air mercury released from dental amalgam
M.J. Vimy,F.L. Lorscheider +1 more
TL;DR: It is concluded that intraoral air is a reliable physiological indicator of Hg released from dental amalgam that may reflect a major source of chronic Hg exposure.

Clearance of Mercury (Hg-197, Hg-203) Vapor Inhaled by Human Subjects
TL;DR: Five human subjects inhaled a mixture of stable and radioactive mercury vapor for periods of 14 to 24 minutes and retained an average of 74% of that inhaled mercury, evidence is submitted to show that the retention occurred almost entirely in the alveoli.

The Effect of Dental Amalgams on Mercury Levels in Expired Air
Carl W. Svare,L.C. Peterson,John William Reinhardt,Daniel B. Boyer,Clyde W. Frank,Robert D. Cox +5 more
TL;DR: In situ dental amalgams can increase the level of mercury in expired air, and examined subjects with dental amalgAMS had higher pre-chewing mercury levels in their expired air than those without amalgams.
