Abstract
Reports of allergies related to dental treatment are increasing and the dental materials used are often limited. Herein, we present the case of a patient who had drug eruptions after receiving treatment using multiple dental materials. We performed a patch test on the dental materials, identified the cause of the condition, and provided effective treatment.
Blister formation on the buccal mucosa and skin eruption with keratinization of the dorsum of the hand were observed. Based on the biopsy and clinical findings, the symptom noted on the dorsum of the hand was diagnosed as a fixed drug eruption. However, the cause was unknown. As the patient reported that the symptoms worsened after dental treatment, we decided to perform a patch test using dental materials; based on the results, the oral symptom was diagnosed as contact dermatitis, and the patient’s condition was caused by dental cement including eugenol or methacrylate. Thus, the material was replaced with one whose safety was confirmed by a patch test. The symptoms in the oral cavity were relieved and the symptoms noted on the back of the hand were resolved.
