One of the complications of using metallic filling in mouth is galvanic symptom. When two or several non-homogenous dental materials with different electric potentials lie near, the side effects are metallic taste feeling, irritated feeling in membrane, erythematous region, and gingivitis desquamate. The aim of this study was to assess the presence of symptoms of electro galvanic in Iranian samples.Materials & Methods: This descriptive study was conducted on two groups of 150 patients, 189 female (63%) and 111 male (37%). Assessment was done by oral examinations and filling the questionnaires for records of probable of electro galvanic symptoms. Statistic analysis was done by SPSS.Results: The results indicated that the presence of galvanic phenomena in the case and control group was 82% and 5.3%, respectively. Among them, the most prevalent symptom was metallic taste feelings and the rarest clinical manifestation was erythematic in buccal and lingual mucosa surfaces.Conclusion: According to the results of this study, direct contacts of metallic filling  lying side by side or face to face in proximity of electrolysis solution (saliva) is effective in occurring of galvanic phenomena.
