title: Dental allergic contact dermatitis:  an interesting case series and review of the literature.
abstract: When patients have persistent oral complaints, it is important to consider allergic contact dermatitis to dental components. We present 3 cases seen at the Ottawa Hospital Patch Test Clinic between 2007 and 2009 with persistent oral lesions. Mercury, methacrylate, and beryllium were found to be the responsible allergens after patch testing. Of note, our case is the fourth reported dental contact dermatitis case to beryllium. Subsequently, a literature review and an examination of reported cases and management strategies were done. There is debate over the necessity of changing dental work after a positive patch-test result. We conclude that it is necessary to do your best to uncover all of the materials used in dental work. Often, material safety sheets do not include all allergens present in products. We advocate that if a positive reaction is found and deemed relevant, then appropriate replacement of the offending agent should be recommended.
