Abstract
A 38-year-old dentist developed hand dermatitis associated with the handling of a self-curing resin used in the making of temporary crowns. After several unsuccessful medical interventions, including treatment for dermatophyte infection and psoriasis, patch testing showed positive reactions to both the self-curing resin and ethylene glycol dimethacrylate, one of its principal components, but a negative reaction to methyl methacrylate, a common component in other self-curing resin products. Chemical substitution with another selfcuring resin, containing methyl methacrylate but not ethylene glycol dimethacrylate, was successfully used.
