Abstract:

Urticaria affects ¼ of people at least once in a lifetime. It is a clinical reaction turned by many factors, causing the liberation of vasoactive substances such as kinines, prostaglandins and histamine. Chronic urticaria is classified according its duration to less or more than 6 weeks. Foci of infection in the oral cavity and its relationship with the general health of the patient have been long studied. The oral cavity is considered as intersection of dentistry and medicine and “the window to general health”. Infection from the oral cavity may create or aggravate general health.

We present a clinical case of a 49-years old female patient with chronic urticaria, presented with the typical multiple urtics located mostly on the lateral surfaces of the abdomen – bilaterally. The major complaint was severe itching and burning sensation on the skin.

The patient is referred by colleagues from the Clinic of Clinical Allergology, UMHAT “Alexandrovska hospital”, Medical University-Sofia to the Department of “Imaging and Oral Diagnostics”, Faculty of dental medicine, Medical University-Sofia, to perform a consultation due to the presence of focal infection of dental origin and specific testing for sensitization to dental materials in the oral cavity. The patient underwent dental focal diagnostic protocol. We remarked active dental focus tooth 46. It was endodontically retreated under antibiotic protection and after that chronic urticaria disappeared.
