Allergic contact stomatitis caused by acrylic resin

Abstract

A llergic contact stomatitis caused by resins, particularly self-polymerizing resins, are rare or are rarely reported.*+ When allergic responses have been reported, the responsible agent appears to be residual monomer which is capable of producing a stomatitis and an angular cheilitis.‘, 6, 7 In a previous report of allergy to residual monomer it was suggested that the “cured” material could be treated to remove the residual monomer so that the restoration could still be used in the treatment of a sensitized patient without further adverse reacti0n.j In that report the patient had erythema multiforme, a symptom complex in which allergy is often the underlying cause. The following report concerns another patient who became sensitive to self-polymerizing resin when a permanent maxillary splint was made. The reaction was erythema multiforme, which was treated by removing the residual monomer. The diagnosis of allergy was corroborated by patch testing.
