Chronic urticaria due to dental eugenol.
A case is reported of a patient with chronic urticaria. The correlation between the symptoms and dental treatment gave rise to the supposition that a root canal cement was causing the trouble. A causal relationship with eugenol, a cement constituent, could only be established through provocative oral ingestion. There is a high probability that the oral provocation tests to eugenol are relevant. Nevertheless, caution is needed when dealing with chronic urticaria.
