Polymetallism and oral galvanism - Kawther Bel Haj Salah

Objective: the concretization of the galvanic current created by a coupling of metallic alloys used in dentistry. Materials and methods: For our in vitro study, we prepared six samples of alloys used in dentistry, to play the role of electrodes, and two electrolyte solutions, whose temperature, pH and electrical conductivity were previously measured. In the laboratory of the electric department of the ENIM, we realized a chemical pile constituted by a GBF (in alternating current), an ammeter and..
