The purpose of this review was to evaluate allergic manifestations to dental local anaesthetic (LA) in children and to propose an algorithm for the diagnosis of LA allergy, in order to minimise the number of children who are wrongly categorised as allergic.
Material and methods
A comprehensive literature survey was performed on LA allergy in children before a dental treatment. In proposing a diagnostic algorithm, evidences from literature have been integrated with personal experience.
Data from literature showed that overall less than 1% of young patients tested for suspected LA have a positive subcutaneous test and have a positive diagnosis. A complete diagnostic procedure should include: clinical history reported by patients, objective medical records, results of skin tests and provocation test with the suspected drug. Patients with negative skin tests should perform a subcutaneous challenge, while patients with a positive skin test should be tested for a different unrelated LA.
Allergy to LA is a rare condition. A complete diagnostic algorithm will allow to identify paediatric patients correctly.
