In Canada, amalgam use is considered safe and effective by some groups. A 2005 position statement from the Canadian Dental Association (CDA) states "current scientific evidence on the use of dental amalgam supports that amalgam is an effective and safe filling material that provides a long-lasting solution for a broad range of clinical ...
Amalgam is typically compared to resin-based composites because many applications are similar and many physical properties and costs are comparable. Dental amalgam has been studied and is generally considered to be safe for humans, [10] [11] though the validity of some studies and their conclusions have been questioned. [12]
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.
[54] [55] Silver is also a component in dental amalgam. Silver acetate has been used as a potential aid to help stop smoking; a review of the literature in 2012, however, found no effect of silver acetate on smoking cessation at a six-month endpoint and if there is an effect it would be small. [56]
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 ...
Unlike amalgam, which just fills a hole and relies on the geometry of the hole to retain the filling, composite materials are bonded to the tooth. In order to achieve the necessary geometry to retain an amalgam filling, the dentist may need to drill out a significant amount of healthy tooth material.
An amalgam is an alloy composed of mercury and other metals.[1] Dental amalgam is produced by mixing liquid mercury with an alloy made of silver, tin, and copper solid particles.[1] Small quantities of zinc, mercury and other metals may be present in some alloys.[1] This combination of solid particles is known as amalgam alloy.[1]
Hal Alan Huggins (1937 – November 29, 2014) was an American alternative dentistry advocate and campaigner against the use of dental amalgam fillings and other dental therapies that he believed to be unsafe. [1] [2] Huggins began to promote his ideas in the 1970s and played a major role in generating controversy over the use of amalgam. [3]
