Successful coating of an allergenic acrylate-based dental prosthesis*1

Background: Most dental prostheses are currently made of acrylate compounds. Therefore, patients sensitized to acrylate compounds may have difficulties in finding prostheses. Objective: A patient with allergic prosthesisinduced stomatitis who was able to use the prosthesis after her allergenic acrylate-based dental prosthesis had been coated with a UV light—cured acrylate lacquer is reported. Methods: The patient was patch tested with the standard series, the dental screening series, the (meth)acrylate series, the plastics and glues series, and commercial prosthesis materials. Patch testing was performed with a 48-hour occlusion time and readings after 2 days and 3 or 4 days. Results: On patch testing, the patient had allergic patch test reactions to methyl methacrylate (MMA), 2-hydroxyethyl methacrylate, 1, 4-butanedioldiacrylate, and ethylene glycol dimethacrylate. Her prosthesis was then coated using a UV light—cured acrylate lacquer containing MMA, and she could wear the prosthesis without adverse side effects. Conclusions: Evidently, the surface of the UV light—cured, acrylate-based prosthesis polymerized so completely that residual MMA caused no clinical symptoms. UV light—cured coating of allergenic acrylate prostheses is recommended for patients with allergic problems from acrylate compounds.
