Oral lichenoid reaction, dental amalgam, and tin allergy.

摘要

In their informative brief report on the treatment of oral lichenoid reaction with dental amalgam removal in a patient who received 2 mercury amalgam fillings and in whom a lichenoid contact mucositis subsequently developed, Aggarwal et. al found that their patient had a positive allergic reaction to 2 different amalgam allergens revealed by skin patch testing: pulverized amalgam alloy and tin. These important clinical findings add to the growing evidence of a strong link between allergy to intraoral metals and amalgam associated with oral lichenoid reactions. However, we would like to comment on some issues that are not discussed in this case report but that, in our view, should be considered.
