Suspected Local Anesthetic Allergy of a Child: A Case Report

Local anesthetics (LAs) are essential in dental practice. Although hypersensitivity reactions are especially rare and account for less than 1% of all adverse reactions, exposure to allergens can cause a lifethreatening allergic reaction known as anaphylactic shock [1-4]. We sometimes encounter patients who believe that they have LA allergy on the basis of their experiences of developing various symptoms after injection of LAs. However, we often find it difficult to detect and to diagnose LA allergy partly owing to the low reliability of the allergy tests [5]. Here, we examined the use of LAs in a child with suspected LA allergy.
