Oral Allergy Syndrome (OAS) is a type of cross-allergy in people allergic to pollen, manifested by inflammation, itching, burning and redness of the oral mucosa and lips after eating raw vegetables containing the PR-10 allergen, including: apples, cherries, strawberries, tomatoes, peaches and many others. This is a particularly important issue for the dentist as he or she is often the first person to come into contact with a patient suffering from OAS. The role of the dentist in the management of OAS is to make an initial diagnosis and refer the patient to an allergist. The diagnosis of OAS is based on a medical interview, skin testing and IgE antibody testing. Treatment of OAS includes an elimination diet, the use of antihistamines or steroids for more severe forms of OAS, and immunotherapy. A patient with OAS requires interdisciplinary care from doctors of many specialties including periodontists, allergists and laryngologists.

Key words: allergy, oral mucosa, interdisciplinary treatment.
