Abstract

A dental assistant developed sensitivity to dental restorative materials within 3 months of starting to use them. They contained the epoxy acrylate BIS-GMA, which is the most commonly used dimethacrylate monomer in dental composite restorations. She was positive to a patch test with BIS-GMA, which was the probable allergen, and epoxy resin, but this substance was not present in the materials used, as shown by high performance liquid chromatography. The patient was also allergic to the disinfectant Desimex i containing dodecyl diaminoethyl glycine.
