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.
Better dental health overall coupled with increased demand for more modern alternatives such as resin composite fillings (which match the tooth color), as well as public concern about the mercury content of dental amalgam, have resulted in a steady decline in dental amalgam use [82] in developed countries, though overall amalgam use continues ...
Composites and amalgam are used mainly for direct restoration. Composites can be made of color matching the tooth, and the surface can be polished after the filling procedure has been completed. Amalgam fillings expand with age, possibly cracking the tooth and requiring repair and filling replacement, but chance of leakage of filling is less.
An amalgam dental filling. Dentistry has used alloys of mercury with metals such as silver, copper, indium, tin and zinc. Amalgam is an "excellent and versatile restorative material" [9] and is used in dentistry because it is inexpensive and relatively easy to use and manipulate during placement. It remains soft for a short time so it can be ...
Auguste Taveau (Louis Augustin Onésiphore Taveau) was a French dentist born in Le Havre, the 28th of August 1792. [1] Date and place of his death are still unknown. In 1826, he was among the first to use amalgam as a dental restorative material, [2] although he had originally developed it as early as 1816.
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 ]
When amalgam fillings are drilled for height adjustment, repair or replacement, some mercury-containing amalgam is inevitably washed down drains. (See Dental amalgam controversy - Environmental impact) When amalgam fillings are prepared by dentists, improperly disposed excess material may enter landfills or be incinerated. Cremation of bodies ...
He is also known for his principles of tooth preparations, in which he outlines the proper methods to prepare teeth for fillings. These cavity preparations used principles of engineering and material sciences to maximize strength and retention of the amalgam filling and minimize fractures as well as tooth anatomy, to minimize pulp exposure.
