Orthodontic headgear related to allergic contact dermatitis: a case report.

A case is reported of a 13-year-old girl who developed a facial rash shortly after orthodontic headgear was fitted. Patch testing revealed that she was strongly allergic to nickel and also allergic to cobalt and chrome. A diagnosis of allergic contact dermatitis was made. Painting the metal buckle of the cervical strap with polyurethane paint prevented further development of her rash, while allowing her orthodontic treatment to progress.
