Abstract:In the restoration of lost or misaligned dental pieces, dissimilar dental alloys are frequently used in the oral cavity, which form galvanic couples that corrode due to the effect of saliva and dentin fluids. In this work, the microstructure of ten non-precious dental alloys was analyzed by optical microscopy, the open-circuit corrosion potential of each alloy was measured against a saturated calomel electrode, they were subjected to accelerated corrosion processes in aerated artificial saliva and plotted the … Show more
