A 59-year-old woman noticed a swelling and redness in the buccal and palatal mucosa 12 h after setting of a temporary crown (TEK) made of self-curing resin at a dental clinic. When she came to our hospital, the edema and redness in the buccal and palatal mucosa around the right upper molar were seen. The TEK had already been removed at the clinic. We suspected an allergy to TEK, and performed a patch test to the chemicals of the resin. The only liquid component of resin showed a positive reaction. Topical glucocorticoid ointment was applied, and the symptoms almost subsided 3 days later.
