title: [Clinical and microstructural comparative studies on fillings made from gallium-tin-nickel alloys and from silver-tin amalgam].
abstract: The filling material "Gallodent" has been clinically controlled for a period of one year. Scanning electron microscopic examinnations revealed greater surface porosity with negligible microleakage and better marginal adaptation as compared to amalgam. Early corrosion phenomena required re-polishing every three months. This disadvantage and the brittleness of the gallium-tin-nickel alloys hinder, at present, these alloys from superseding high-silver amalgams.
