Allergic reactions are relatively rare in the dental office. Nevertheless, it is important for the dentist to be able to identify allergic reactions and to act accordingly. The type of allergic reactions may be immediate (Type I), for instance related to latex, penicillin, or food components, or delayed (Type IV), for instance related to amalgam, gold, palladium, composite, or nickel. In most cases, the clinical features described below are sufficient for the correct diagnosis.
