Oral allergies to dental materials.

Oral allergies represent a pathological entity not well known nor diagnosed by dental health professionals. The purpose of this work is to present an information relative to the multidisciplinary steps to be done to solve allergy problems. Three clinical examples of contact oral allergies (to mercury, or gold, or methacrylates) are presented, as to illustrate signs and symptoms of an oral allergy to the more frequent dental materials implied.We discuss the problem of oral allergies from what is known from the scientific literature. We stress the importance of a multidisciplinary approach to take into account patients with an oral allergy, with participation of specialists from dental and dermatologic fields.
