An unusual skin reaction following local anesthetic injection. Review of the literature and report of four cases.
Four cases of an unusual skin eruption related to mandibular block injection are presented. The authors suggest an immunologic basis for the reaction, probably to the methylparaben preseravtive, and discuss a possible pathogenic mechanism. The medical-dental literature concerning untoward reactions to lidocaine is reviewed; particular attention is given alleged allergic reactions.
