Abstract:
Epoxy resin based on Diglycidyl-ether-Bisphenol-A has been commonly used in dental fillings and dentures. Epoxy resin is a well known low molecular weight chemical sensitizer, but contact urticaria from epoxy resin has been infrequently reported despite it's wide use in dental practice. We report a case of a 48-year-old housewife who presented a recurrent episode of perioral erythema and angioedema associated with dental work. These symptoms, which occurred within 2 hours of having dental fillings, were aggravated with repeated dental procedures for a period of several days. Her symptoms improved after removal of dental fillings. Her contact urticaria to epoxy resin was reproduced by patch test with AH26 root canal sealer containing Bisphenol-A type epoxy resin. Delayed type reaction to epoxy resin was also noted. Her symptoms did not reoccur after use of another type of root canal sealer.
