Influences of clinical factors on marginal adaptation and residual mercury content of amalgam. 1975

R J Mathewson, and K H Lu

Clinical factors affecting residual mercury and marginal adaptations of amalgam restorations in a private practice environment were investigated. Findings, converted to ridit values, indicated that influencing factors are the training level of the dental assistants, type of amalgamator, accuracy of the timing device, and method of condensation.

D008628	Mercury	A silver metallic element that exists as a liquid at room temperature. It has the atomic symbol Hg (from hydrargyrum, liquid silver), atomic number 80, and atomic weight 200.59. Mercury is used in many industrial applications and its salts have been employed therapeutically as purgatives, antisyphilitics, disinfectants, and astringents. It can be absorbed through the skin and mucous membranes which leads to MERCURY POISONING. Because of its toxicity, the clinical use of mercury and mercurials is diminishing.
