title: Delayed extraoral hypersensitivity to dental composite material.
abstract: Despite their similarities to acrylic resins, composite resins have not been reported to cause allergies. This report documents the case of a patient who experienced several delayed hypersensitivity reactions associated with epoxy-based materials, including dental composite resin. Patch testing confirmed her hypersensitivity to the composite materials. Removal of the composite restorations and replacement with acrylic restorations did not trigger further allergic reactions. Dentists using composite resin materials should be aware of both the possibility of delayed extraoral manifestations of hypersensitivity to those materials and the management of these patients.
