title: Severe abrasion of composite and amalgam restorations in a patient with lupus erythematosus systemic. Case report.
abstract: A case of repeated severe abrasion of amalgam and composite resin restorations in a patient under treatment for Lupus erythematosus systemic is reported. The patient had a history of audible nocturnal bruxism. Severe roughening occurred within three weeks of placement of the restorations and was related precisely to surfaces in contact with the opposing restored dentition. Examination by SEM revealed an unusual wear pattern of the amalgam restorations.
