Oral lichenoid lesions associated with amalgam restorations: report of two cases Lesões liquenóides bucais associadas a restaurações de amálgama: relatos de dois casos
نویسندگان
چکیده
Purpose: Dental amalgam has been used as a dental restoration for more than 165 years. However, some patients with these restorations may present oral lichenoid lesions (OLL). OLL are chronic oral mucosal contact reactions to dental amalgam. Their diagnosis usually is based on the direct contact of the affected mucosa with the amalgam restorations, clinical appearance, and lack of migrations. A patch-test for mercury can be performed to confirm the diagnosis. Thus, the objective this work was to discuss the occurrence of this disease and your possibilities of existing differential diagnostic.
