“…This includes the possibility that the results could be a result of cross reactivity or more likely a broad increase in sensitivity to all allergens as a result of compromised skin barrier condition as is a well-recognised phenomenon in dental industry. (13,14) We presume that the process has a local character. However, the impact area and borders are subject of discussion.…”

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. Background:The allergic contact dermatitis (ACT) is the most frequent manifestation of immunotoxicity in humans. (1) The disease has a strong social and economic effect .(2) ACT is a the 4-th type reaction by the classification of Coombs and Gell. The allergic reactions that we observed in patch-tests, can be measured by the temperature changes of the affected skin.(3,4) The method we applied to measure the patch test reactions, is also applicable for measurement of the intensity of the allergic reaction of the affected skin.(5) However, some studies show that the local lymph nodes are also involved in the reaction.(6) Initially we assumed that our patient`s symptoms are connected with the acrylic products

“…However, the impact area and borders are subject of discussion. The allergic reactions are functions of the immune system, so we can expect the whole immune sults could be a result of cross reactivity or more likely a broad increase in sensitivity to all allergens as a result of compromised skin barrier condition as is a well-recognised phenomenon in dental industry [13,14].…”

Background: Nail biting can increase the risk of infection and abnormal-looking nails. The purpose of the present investigation was to formulate and evaluate anti-nail-biting lacquers consisting of bitter herbal extracts. Methods: The hydroalcoholic extracts obtained from Andrographis paniculata and Tinospora crispa were determined for phytochemical constituents, total phenolic contents, antioxidant activities, anti-inflammatory activities, and cytotoxicities. Anti-nail-biting lacquers were prepared by using herbal extracts (bittering agent), shellac (film forming polymer), ethanol (volatile solvent), and other indispensable additives with continuous stirring. Thus, attempts to enhance the film property and bitterness is accomplished by using polyvinylpyrrolidone K30 as a copolymer and varying concentrations of herbal extracts. Good accepted formulations were established for drying time, pH, viscosity, smoothness of film, film strength, water resistant, and solubility in simulated saliva and then evaluated their bitterness in human volunteers.Results: Phytochemical constituents including tannins, glycosides, reducing sugars, alkaloids, terpenoids, and flavonoids were found present in both extracts while saponins was only detected in A. paniculata extract. Although T. crispa extract exhibited a significantly higher (p < 0.05) total phenolic content and antioxidant activity than A. paniculata extract, it showed lower protein denaturation inhibition property than A. paniculata extract. Because of the potentials of both extracts without cytotoxicity, anti-nail-biting lacquers containing either A. paniculata extract or T. crispa extract were developed and evaluated. Drying time of formulations were 6-11 min with visually seen glossiness of formulation. Formulations of the nail lacquer showed good pH, viscosity, smoothness of film, film strength, water resistant, and solubility in simulated saliva. The formulations displaying no significant cytotoxicity effect on CRL-2076 cells were assessed on healthy human volunteers to compare bitterness and film characteristics. Conclusion: The optimized formulation containing A. paniculata extract could successfully achieve good film forming property and bitterness release which is considered promising for stopping nail biting.
