Galvanic shockororal galvanism is a term used for the association of oral symptoms due to electric currents occurring between different types of metal used in amalgamdental fillings and their interactions with the electrolytesinsaliva.[1][2] Other than individual sensitivity to amalgam, which can produce oral lesions, no associated adverse effects to amalgam have been found.[3][4] However, Mutter in a German study concluded that "removal of dental amalgam leads to permanent improvement of various chronic complaints in a relevant number of patients in various trials".[5]
The condition of galvanic shock was originally proposed in 1878,[6] and became well known in Sweden during the 1970s and 80s, because of a campaign to raise awareness, and replace dental amalgam fillings containing mercury with other compounds such as ceramicorpolymer restorations.[2]
