AbstractOral cavity and perioral area are constantly exposed to a variety of antigens, including food and additives, which have a potential role in the development of different oral mucosal and perioral cutaneous diseases since they can cause hypersensitivity reactions. Oral and perioral diseases mainly include angioedema, burning mouth syndrome, cheilitis, gingivostomatitis, oral lichenoid reactions, and perioral dermatitis. Previous studies were focused on delayed-type oral allergies by performing patch testing but did not include tests for immediate-type allergic reactions. Therefore, the objective of this study was to determine common nutritive and additive allergens in the prevalent oral and perioral diseases by using skin prick tests. Our study evaluated 230 participants, i.e. 180 patients with oral/perioral diseases (angioedema, burning mouth syndrome, cheilitis, gingivostomatitis, oral lichenoid reactions, and perioral dermatitis), and 50 healthy control subjects. The results of skin prick tests showed that immediate-type allergic reactions to food and additives were mostly seen in patients with burning mouth syndrome (40%) and cheilitis (33.3%), whereas allergies were least frequently observed in perioral dermatitis (10%) and gingivostomatitis (20%). Fruits, mushrooms, and vegetables were the most frequent causes of nutritive allergies in oral and perioral diseases. The most commonly identified additive allergens were glutaraldehyde, citric acid, and sodium glutamate. Study results suggest the possible association with nutritive and additive allergies be considered in cases of persistent oral mucosal or perioral skin disease accompanied by respective medical history.
