Oral cavity, including the lips, is permanently exposed to a wide spectrum of potential allergens during dental treatment, oral hygiene

and also in connection with flavorings and conservants in pharmaceutical products and cosmetics. The aim of the study was to assess

a sensitizing potential of dental materials and other oral contactants using standard patch tests. The greatest frequency of sensitization in

343 patients with various clinical presentations of oral discomfort was confirmed to dental metals nickel sulfate (11,4 %), goldsodiumthiosulfate

(9,6 %), palladium chloride (8,5 %), mercury (6,7 %), potassium dichromate (6,1 %), amalgam (5,5 %), cobalt chloride (4,9 %) and

balsam Peru (7,6 %). Twenty substances with the highest percentage of positive reactions were proposed as an oral screening series.
