Why do solder joints in sometypes of Orthodontic appliances like space maintainers turn black?
Solder joints in orthodontic appliances like space maintainers can turn black due to the formation of corrosion products, primarily from the interaction of moisture and saliva with the metal. This can occur if the solder contains non-precious metals that are more prone to oxidation. Additionally, the presence of plaque or food debris can accelerate corrosion, leading to discoloration. Over time, these factors can compromise the integrity of the solder joint, potentially affecting the appliance's functionality.
