Allergic Reaction to Zirconia Ceramic Bridge Cementation Using a Dental Adhesive Resin Cement: a Case Report

Resin materials are commonly used in various dental treatments in patients with metal allergies. Recently, some reports have revealed the association between resin materials and allergic reactions. However, no study has assessed the association between dental adhesive resin cements and allergic reactions. We present the case of a 56-year-old woman with a history of allergic reaction to pollen, iodine, and platinum and some metals. She received periodontal and prosthodontic treatments for 4 years. In the middle of May 2019, a zirconia bridge was cemented to the right molar region of the upper jaw using a dental adhesive resin cement. Two days later, she complained of pain in the tongue, swelling and blistering of the lips, and respiratory stenosis. At the end of May, her temporary bridge was adjusted, and she immediately experienced symptoms similar to those she had after the zirconia bridge cementation. The patient was suspected to have an allergic reaction to the resin. Thus, she underwent an allergy patch test for different dental materials, including some adhesive resin cements. The patch test results revealed a positive allergic reaction to tooth primer on days 2, 3, and 7 and to light-cured adhesive resin paste on day 7. Additionally, the test revealed a false-positive reaction to a self-cured acrylic resin on day 7. However, there were no positive reactions to other adhesive resin cements and glass ionomer cements. Some types of adhesive resin cement may induce an allergic reaction in patients sensitive to different materials. In such a case, we should choose a glass-ionomer cement instead of adhesive resin cement.
