Amalgam filling on first molar. In dentistry, amalgam is an alloy of mercury used to fill teeth cavities. [1] It is made by mixing a combination of liquid mercury and particles of solid metals such as silver, copper or tin.
Amalgam is a metallic filling material composed from a mixture of mercury (from 43% to 54%) and a powdered alloy made mostly of silver, tin, zinc and copper, commonly called the amalgam alloy. [16] Amalgam does not adhere to tooth structure without the aid of cements or use of techniques which lock in the filling, using the same principles as a ...
The two case studies illustrate the method's conservative nature and present a viable option for patients with enamel infractions who would prefer not to undergo more invasive procedures. [16] In another article, it emphasizes how the detection of enamel cracks has greatly improved due to recent technological advancements like transillumination ...
The composition of dental amalgam is controlled by the ISO Standard for dental amalgam alloy (ISO 1559). [12] The major components of amalgam are silver, tin and copper. [12] Other metals and small amounts of minor elements such as zinc, mercury, palladium, platinum and indium are also present. [12]
The history of dental treatments dates back to thousands of years. [1] [2] The scope of this article is limited to the pre-1981 history.The earliest known example of dental caries manipulation is found in a Paleolithic man, dated between 14,160 and 13,820 BP. [3]
Oral galvanism, amalgam disease, or Galvanic shock was a term for the association of oral or systemic symptoms to either: electric currents between metal in dental restorations and electrolytes in saliva or dental pulp. [45] [46] [47] Any existence of galvanic pain or association of either currents or mercury to presence of symptoms has been ...
[6] [8] [9] The unit failed to gain wide popularity due to several factors, including the inability of air abrasion to prepare the well-defined margins and walls needed for the amalgam restorations used at the time, the lack of high-velocity suction available for powder control, and the introduction of the time-saving air turbine drill. Air ...
Systematic reviews and meta-analyses show that there are no differences between ART/HVGIC restorations in terms of longevity in primary teeth (for both single- and multiple-surface lesions) compared to the conventional methods using either amalgam [19] [20] [21] or resin composite. [22] [23]
