Gallium alloy versus high copper amalgam: a comparative evaluation of corrosion resistance and microleakage in the primary teeth
A.K. Munshi / Amitha M. Hegde / Sajith Bhaskar

In vivo corrosion and in vitro microleakage of a gallium based and a high copper amalgam alloys were evaluated.Twenty-five primary molars each were restored with Galloy and DPI alloy respectively and evaluated, over a period of three months, for various aspects of corrosion in the oral cavity. Additionally ten primary molars were utilized for evaluation of microleakage by dye penetration after having them restored with the two materials. Gallium alloy restorations showed better marginal adaptation, clinically when compared to amalgam restorations. No significant difference was observed for the degree of microleakage around gallium alloy and amalgam restorations.
