283 - Clinical Implications of Nickel Allergy in Pediatric Dentistry: A Case Report

Abstract: Nickel allergy is a relatively common contact hypersensitivity in children with important implications in pediatric dentistry due to the widespread use of nickel-containing dental materials. Exposure may occur through orthodontic appliances, including braces and wires, as well as stainless steel crowns, potentially leading to localized or systemic allergic reactions. Clinical manifestations can include oral mucosal erythema, ulceration, gingival inflammation, and perioral dermatitis, which may complicate dental treatment and affect patient comfort and compliance.
This case report describes a pediatric patient who developed signs consistent with a nickel hypersensitivity reaction shortly following placement of braces and nickel-titanium wires. Diagnosis and management of the treatment plan are discussed, including material substitution with nickel-free alternatives. The case highlights the importance of thorough medical and allergy histories, and early recognition of hypersensitivity reactions in dentistry. Increased awareness of nickel allergy allows dental providers to minimize adverse reactions while maintaining effective restorative and orthodontic care.
