[Allergic reactions to orthodontic materials and a protocol for the management of patients].

Performing orthodontic treatment in patients presented with history of allergy is not frequent, but still not unusual. It is absolutely necessary that the orthodontist realizes the possibility of patient's hypersensitivity towards the various orthodontic materials, especially the ones which contain nickel. Information regarding previous allergic reactions, reference of the patient for epicutaneous patch testing and modification of the treatment plan are important components of the proper management of such patients in the orthodontic practice.
