galvanism

 [gal´van-izm]
1. a unidirectional electric current derived from a chemical battery.
2. the therapeutic use of such a current.
dental galvanism the production of galvanic current in the oral cavity due to the presence of two or more dissimilar metals in dental restorations that are bathed in saliva, or a single metal and two electrolytes (such as saliva and pulp tissue fluid); sometimes the current may be high enough to irritate the dental pulp and cause pain.

gal·va·nism

(gal'vă-nizm),
1. Direct current electricity produced by chemical action, as by a battery.
2. Oral manifestations of direct current electricity occurring when dental restorations with dissimilar electric potentials (for example, silver and gold) are placed in the mouth; characterized by pain or development of small areas of leukoplakia.
Synonym(s): voltaism

2. the therapeutic use of this current, particularly for stimulation of nerves and muscle.galvan´ic

dental galvanism  production of galvanic current in the oral cavity due to the presence of two or more dissimilar metals in dental restorations that are bathed in saliva, or a single metal restoration and two electrolytes, saliva and pulp tissue fluid, thus producing an electrolytic cell and an electric current. When such restorations touch each other, the current may be high enough to irritate the dental pulp and cause sharp pain. The anodic restoration or areas of a restoration are subject to electrolytic corrosion.

galvanism

n.
1. Direct-current electricity, especially when produced chemically. Also called voltaism.
2. Therapeutic application of direct-current electricity, especially the electric stimulation of nerves and muscle.

Galvani,

Luigi, Italian physician and anatomist, 1737-1798.
galvanic bath - water bath that is charged with galvanic current.
galvanic current - continuous one-direction electric current.
galvanic skin response - skin's response to electric stimulation. Synonym(s): electrodermal response
galvanic-faradic test - an electrodiagnostic test of muscles.
galvanism - oral manifestations of direct current electricity occurring when dental restorations with dissimilar electric potentials (such as silver and gold) are placed in the mouth. Synonym(s): voltaism
galvanometer - an instrument used to measure current.

negative galvanism

application of direct electrical current to cauterize exposed nail matrix; its effectiveness as an ablation agent depends on the magnitude and duration of applied current
