D2.27 - “Chronic Urticaria Following Dental Filling Procedure: A Clinical Evaluation”

Abstract

Chronic urticaria (CU) can arise from various triggers, including medication, food, and environmental factors. This case report details a 37-year-old woman whose chronic urticaria developed following a dental filling procedure. Through careful evaluation and testing, it was determined that the dental material was the primary trigger. Following the removal of the dental filling, the patient experienced significant improvement and resolution of symptoms.

Introduction

Chronic urticaria is characterized by the recurrent appearance of wheals, angioedema, or both, lasting for more than six weeks. Identifying specific triggers is essential for effective management. This case highlights the importance of considering dental materials as potential triggers for chronic urticaria.

Patient History

The patient, a 37-year-old woman, presented with a primary complaint of persistent itching and the presence of hives that began after a dental filling procedure. The symptoms started around one week post-procedure and were accompanied by significant discomfort, impacting her quality of life.

Diagnostic Workup

Initially, the patient underwent evaluation, which included:

Total and Specific Immunoglobulin E (IgE): Results were within normal limits, indicating no significant allergic response based on standard IgE testing.

Skin Test: A subsequent skin test was conducted to identify specific triggers related to the dental filling material. The results confirmed that the dental material was indeed responsible for the development of chronic urticaria.

Management and Outcome

After confirming the trigger, the dental filling was promptly removed. Following the extraction procedure, the patient reported gradual improvement in her symptoms. Over the course of two months, the frequency and severity of urticaria decreased significantly.

At the follow-up visit, the patient was symptom-free, and there were no adverse reactions associated with the dental filling replacement, which utilized alternative materials. The patient's quality of life significantly improved, and she was advised on strategies to avoid similar triggers for future dental procedures.

Discussion

This case highlights the importance of healthcare providers considering dental materials as potential allergens in patients presenting with chronic urticaria. A thorough history and appropriate testing can lead to effective treatment and resolution of symptoms.

Conclusion

Chronic urticaria can be precipitated by specific triggers such as dental fillings. Recognizing and removing the offending material led to the successful management of this patient’s condition. Increased awareness of potential triggers in clinical practice can enhance patient care and outcomes.
