Impact of Dental Procedures on Hereditary Angioedema Attacks: An Exploratory Observational Study.

Swelling related to dental procedures was common among the studied HAE patients. Unwarranted medications used before HAE diagnosis for dental post-procedural symptoms were replaced by adequate HAE-specific medications in most patients with established HAE diagnosis. A statistically significant proportion of patients refrained from undergoing dental interventions, and some of them were refused dental care by oral health professionals due to fear of HAE attacks.
