Metal ion release from silver soldering and laser welding caused by different types of mouthwash.

Objective: To compare metal ion release from samples welded with silver soldering and laser welding when immersed into mouthwashes with different ingredients.

Materials And Methods: A total of 72 samples were prepared: 36 laser welded and 36 silver soldered. Four samples were chosen from each subgroup to study the morphologic changes on their surfaces via scanning electron microscopy (SEM).
