Nickel allergy in relation to piercing and orthodontic appliances-a population study
Contact Dermatitis, 05/31/2012
Fors R et al. – High nickel–containing orthodontic appliances preceding piercing reduces the risk of nickel sensitization by a factor 1.5–2. The risk reduction is associated with estimated nickel release of the appliance and length of treatment. Sex, age at piercing and number of piercings are also important risk indicators. Research on the role of dental materials in the development of immunological tolerance is needed.
