CHRONIC urticaria often is a most puzzling process of obscure origin, since it may arise from many different causes. It is customary to consider the role of infection, emotions, and also allergy to common substances in the environment, particularly drugs. The relation of active dental infection to chronic urticaria frequently is sought, yet there are few detailed reports of the incidence and importance of such a relationship.1 We therefore undertook to study chronic urticaria in a group of patients who had been given complete dental examinations, to see how often dental infection occurred, and the effect of eradication of dental infection when present.
Method of Study
Records of 100 patients with chronic urticaria who had been referred to our dental department were reviewed to determine the incidence of dental infection present, and whether or not there was a correlation between appropriate dental treatment and the course of the urticaria.
Criteria. For the purpose of this study, chronic urticaria is defined as persistent or recurring urticaria, with or without angioedema, of more than four weeks’ duration. The eruption had been present for many weeks or months in most cases; up to 10 years in several cases, and intermittently from childhood in a few adults. The cause was obscure in all cases. Some patients had been referred to the dental department in the search for foci of infection, and some patients had been referred because of dental symptoms and signs noted at the time of the initial complete examination.
