Case of oral lichen planus due to dental metal allergy

Abstract

PATIENT: This clinical report describes the treatment of a patient who experienced a hypersensitivity reaction associated with prosthetic restorations fabricated with a silver-palladium-copper-gold alloy. DISCUSSION: Patch testing revealed an allergy to the palladium substrate. Allergic symptoms disappeared from the patient's mucous membrane after all the prosthetic restorations in the patient were replaced with those fabricated using some alternative alloys. The case presented indicates that the release of palladium from prosthesis fabricated with dental metal alloys is able to induce hypersensitivity reactions resulting in soft-tissue changes in the buccal mucosa. CONCLUSION: Dental procedures as a multidisciplinary approach to the care taking of patient are presented.
