Background: Previous studies have reported an increase in the mercury release from dental amalgam restorations, following exposure to electromagnetic fields generated by sources such as mobile phones and magnetic resonance imaging (MRI). It has also been shown that MRI increases microleakage of amalgam restorations. In this study, Helmholtz coils are used for generating pulsed electromagnetic fields (PEMF). Objectives: The purpose of this study was to evaluate the effect of PEMFs on microleakage of amalgam restorations, using a pair of Helmholtz coils. Results: There was no significant difference between the two groups regarding the microleakage score. Conclusions: The results of the present study suggest that PEMF exposure does not have adverse effects on microleakage of amalgam restorations.
