Allergy to acrylate in composite in an orthodontic patient: a case report

Acrylate allergies have been reported in dental professionals as a result of repeat exposure to various acrylate monomers and in dental patients with removable prostheses or longstanding composite restorations. To date, there is only one report of an allergic reaction in a young patient from small volumes of resin-based orthodontic adhesive. This case report demonstrates a recent case of gingival inflammation and lip oedema attributed to an acrylate allergy arising from the composite adhesive used with fixed appliances. The impact on orthodontic treatment is reported and the wider implications for dentistry are discussed.
