title: Management of diffuse tissue argyria subsequent to endodontic therapy: report of a case.
abstract: A case of severe mucogingival argyria secondary to leakage around and corrosion of silver cone root canal obturations and apical amalgam restorations is presented. Following removal of the silver points and re-treatment of the root canals, periradicular surgery was performed to remove the amalgam root-end restorations and reduce the amount of dispersed metallic particles in the subcutaneous tissues. Subsequent free gingival grafting created an esthetically pleasing and biologically acceptable result.
