[Mercury release from amalgam into saliva. An in-vitro study].
The aim of the study was to investigate mercury release into salivary fluid and to test whether this release is associated with flow rate, buffer capacity or pH of salivary fluid. Salivary fluid was collected from 18 persons (11 with amalgam fillings, 7 without) and the surface area of the fillings was assessed. Mercury loss in unstimulated saliva was 11.6 ng/min for persons with amalgam and 2.1 ng/min for those without. Multiple regression analysis revealed no association between flow rate, buffer capacity or pH of unstimulated salivary fluid and mercury release.
