title: Contact allergy to dimethacrylate.
abstract: Contact allergy to methacrylates is uncommon. We present a 55-year-old woman with a 10-year history of persistent pruritus and burning sensation of the gums every time she wore her dentures. Initially she developed swelling and erythema of the face soon after the dentures were placed on the gums. These symptoms abated after a barrier liner was applied between her gums and the dentures. However, the burning sensation and pruritus of the gums progressively worsened and she started to develop blisters on the gums. The skin allergen patch test was 3+ positive with erythema, edema, papules, ulceration, and pruritus for the denture component dimethacrylate. The diagnosis was supported by the patient's medical history, notably positive patch test, and complete amelioration of the symptoms upon cessation of dimethacrylate denture usage.
