Background
Palladium belongs with rhodium, ruthenium, iridium, and osmium to the platinum
group of metals. These elements have considerable corrosion resistance
and are considered precious metals. Because of its relatively low cost,
palladium is one of the most used precious metals. Palladium occurs in
nature alloyed with platinum, gold, and as selenide. Palladium is a good
electrical and heat conductor.
Dental gold, silver, and copper alloys may contain 10% of palladium,
whereas white gold for fine jewelry may contain even 20%.
Vincenzi et al. patch-tested 2300 consecutive patients with paladium
chloride. One hundred seventy one (7.4%) were allergic and 169 were also
nickel-allergic. One hundred and fifty-six of the 171 patients were female.
Wahlberg and Boman showed that palladium was a more potent sensitizer than
nickel in guinea pigs.
