Acrylates and Methacrylates Sensitization in Patients with Orthopedic and Dental Prostheses: Asymptomatic Pre-Implant and Symptomatic Post-Implant Testing.

Acrylates and methacrylates are widely used in dental and orthopedic prostheses, false nails, adhesives, glues, and paints, and are strong sensitizers. The aim of our study was to assess the prevalence of acrylate sensitization in patients before the application of dental or orthopedic prostheses or after the application in case of potentially related contact dermatitis. The subjects were tested according to haptens reported in safety data sheets, including methyl methacrylate (MMA) 5%, methyl acrylate (MA) 1%, ethyl methacrylate (EMA) 2%, ethyl acrylate (EA) 1%, butylacrylate 0.
