Galvanic interaction between titanium and gallium alloy or dental amalgam

摘要

Objectives: The objective was to examine in vitro the galvanic interaction between titanium and a high-copper dental amalgam or a gallium-based direct filling alloy ag different area ratios, and to relate the observed interactions to the electrochemical characteristics of the alloys. Methods: the tested materials were cast titanium, a single-composition, spherical high-copper amalgam, and a gallium-based direct filling Alloy. Polarization curves were recorded.
