Abstract:

A wide variety of materials are used in dental applications and are often faced with allergic reactions. Aliments containing nickel, although they are the most common contact allergens, are widely used in orthodontic materials. Nickel is the most typical antigen that causes allergic contact dermatitis, a delayed type IV hypersensitivity reaction, and can cause intra/extraoral allergic reactions. Oral clinical findings and symptoms of nikel allergy are burning, dental hyperplasia, labial desquamation, angular celitis, erythema multiforme, periodontitis, stomatitis with mild to severe erythema, papules peri-oral erythema, loss of flavor or metallic flavor, swelling and tongue side pain. Nickel allergy is common in society and has a higher rate of occurrence in women. When taking medical and dental anamnesis, patients must be questioned in terms of allergy. The dentist should pay attention to this allergy during orthodontic treatment, know its findings, if it occurs, make it necessary to diagnose and direct it to a specialist. In cases diagnosed with nickel allergy, materials that do not contain nickel should be used. This article discusses the topics of nickel allergy epidemicology, diagnosis, nickel allergy in patients with orthodontic approach and the comparison of nickel content of orthodontic materials.
