[Occupational allergic contact eczema in a dental assistant].
Occupational contact eczemas are very frequent in dental assistants. We present the case of a 46-year-old woman with pruritic, flaky, erythematous-edematous lesions, with indistinct borders, on the backs and sides of the fingers, which had been developing for several months. The skin tests performed with the GEIDC (Spanish Contact Dermatitis Research Group) standard battery, the Chemotechnique dental screening series and her own products showed positivity to nickel sulfate, cobalt chloride, potassium dichromate, gold sodium thiosulfate, the liquid used in endodontics known as "eugenol," fragrance mix and colophony. Eugenol is a perfumed product that is used in cements and sealants for endodontics and periodontology. There are 5 articles regarding cases of occupational allergic contact eczema from this product in dentists or nurses and assistants who work in dental clinics.
