While manufacturing or repairing dentures, dental technicians (DTs) are exposed to uncured plastic resins, mainly acrylates and methacrylates, as liquids or powders, and to metals such as cobalt, palladium, and gold, all of these materials being potential contact allergens . Improved skin protection at the workplace has reduced allergen exposure and the frequency of occupational dermatitis in DTs in the last decades . Nevertheless, allergen contact with the hands, forearms or face still occurs , either because of the wearing of insufficiently protective gloves, or because of airborne dust exposure during the grinding of freshly cured plastic or metal parts. In addition, wearing elastic protective gloves carries the risk of sensitization to rubber chemicals .On the basis of a study on occupational contact dermatitis (OCD) in DTs, and data of the German Contact Dermatitis Research Group (DKG) and the Information Network of Departments of Dermatology (IVDK) from the 1990s , the DKG recommends patch testing DTs with suspected OCD with the baseline series and the DKG test series ‘dental technicians’ and ‘dental metals’ , which have undergone only marginal changes during the last 15 years.
