Hypersensitivity from dental acrylates in a patient previously sensitized to artificial nails.

This article focuses on hypersensitivity from dental acrylates in a patient previously sensitized to artificial nails. A 63-year-old female patient planned to restore her teeth. A temporary crown composed of dimethacrylates and mono-, di-, triglycerin- dimethacrylate-phosphates was fabricated. The night after this intervention the patient experienced painful blisters, oral erythema and oedema of the inner lip on the adjacent mucosa. The symptoms aggravated severely and she visited her dentist 2 days after the second intervention. The dentist prescribed oral corticosteroids that gave only partial relief. The patient has been wearing for years artificial fingernails of the acrylic type without complaints. However when questioned she admitted having had an eczematous reaction to sculptured nails of the photobonded type 3 years before.
