Abstract:

We report the case of a 23-year-old female dental medicine student with contact dermatitis on her hands caused by methacrylates. Forty-eight-hour closed patch testing showed positive reactions to Ethylenglicol dimethacrylate, 1,6 – Hexanediol diacrylate, 1,4 – Butanediol dimethacrylate, Drometrizole . These are identified as contact allergens. They can be found in the dental materials, but also in the nail polish. It is therefore easy to be exposed to methacrylate in daily life. We measured the skin reaction during the patch test, and noticed that the temperature of the affected skin changes. The highest value was registered when the patches were applied, and the lowest – one week after the treatment.
