Background: Anaphylaxis is not common in dentistry, but poor anaphylaxis management may lead to mortality. Objective: The aim of this study was to evaluate dentists’ knowledge and preparedness to manage anaphylaxis. Materials and Methods: The study was designed as an online survey. It included questions about anaphylaxis management practices and the availability of equipment and medications in dental facilities. An online survey link was sent to members of the Turkish Dental Association (TDA). Results: A total of 952 TDA members responded to the survey. Fifty-seven point seven percent of dentists knew that adrenaline is the first choice drug to treat anaphylaxis. Fifty-two point four percent of dentists knew that intramuscular injection is the correct route of administration and 41.7% of dentists knew the correct dose to treat anaphylaxis. Only 15.3% of responding dentists answered all three questions correctly. Dentists who had previously been trained in the diagnosis and treatment of anaphylaxis performed better on questions about the first-choice drug, administration route, and dosage, when compared to untrained dentists (p<0.05). Of the responders, only 4.9% of dental facilities possessed complete medications and equipment capabilities to treat anaphylaxis. Conclusion: The majority of responding dentists did not seem to be aware of anaphylaxis management and did not have adequate equipment and medications for treatment of anaphylaxis in their dental facilities. There is an urgent need for undergraduate and post graduate education programs to increase dentists’ ability to manage anaphylaxis. The availability of emergency anaphylaxis medication and equipment in dental facilities should be ensured.
