A new method to prevent the corrosion of dental metals, during disinfection using functional water: sacrificial protection.
OBJECTIVE
This paper demonstrates a simple method using sacrificial protection for preventing the corrosion of dental metals.


METHODS
Dental metals are directly connected or/and wound with a pure commercial aluminum/zinc wire/plate with high ionization tendency, before their immersion into oxidizing functional water.


CONCLUSIONS
Dental materials such as Co-Cr alloy wires, stainless steel, and Au-Ag-Pd alloys did not corrode when this method was used. Thus, this method is very simple and effective for preventing corrosion of dental metals during disinfection using functional water.
