A 15-year-old girl is at the allergy clinic for evaluation of suspected allergic reaction to dental braces. Braces were placed by an orthodontist 2 months ago, and within a week, she started to feel oral itching and gagging. No history of nickel or latex allergy.
Physical Examination showed mild gingival erythema and dry lips.
What could be the cause of symptoms?
Delayed hypersensitivity to dental braces materials (nickel, cobalt, etc) is rare but described in the literature. Typically, patients have oral or perioral lesions.
What would you recommend?
Regarding the suspected delayed hypersensitivity to dental braces materials (nickel, cobalt, etc), the following is recommended:
- TRUE patch test
- ask the orthodontist to provide the materials of the braces to be added to the patch test
