Contact dermatitis can affect dentists, orthodontists, technicians, nurses and the patients. The increase of dental patients in recent years caused an increase in reports of dermatitis and other allergies in patients and in dentists too. With changes in dental materials through years, allergy and contact reactions in persons in contact with new allergens had been increased. So dentists and dermatologists should be aware of new allergens and try to avoid contact with these materials as possible. This review is performed to increase the knowledge of medical personnel about this issue with description of each allergen.

Background and aim: Contact dermatitis is an inflammatory skin response due to contact with environmental materials manifested as acute or chronic eczema. Patch test is the standard test to recognize responsible allergen. The objective of this study was to evaluate the frequency of false positive patch test responses in patients with Exited Skin Syndrome (ESS).Materials and methods: Fourteen patients older than 12 years with allergic contact dermatitis who had more than one positive reaction in first patch test were re-tested with the same allergens at the time of remission of their eczema. The patches were removed after 48 hours and responses read according to ICDRG guidelines.Results: The patients included 5 men and 9 women with a mean age of 34.92 years. The most common allergens in first patch test were: nickel sulfate (10), cobalt chloride (5), colophony (4), potassium dichromate, PTBF, fragrance mix and MCI/MI (3 each). In the repeated test, the most common positive responses were: nickel (10), cobalt and colophony (4 each), potassium dichromate and fragrance mix (3 each). In 6 of 14 patients the results of second test was different from first one. Three of these patients had active eczema at the time of first test, which in 2 of them one positive response and in one of them, 2 positive responses became negative in second test.Conclusion: It is recommended that patch test be repeated after a while in patients with multiple positive reactions in first test, particularly after remission of active eczema.

Background: Latex allergy is a major occupational disease with prevalence nearly 5-17% among the health care workers. Objective: To determine the prevalence of latex glove allergy and its contributing factors among operation room staff. Patients and Methods: In this study, 512 operation room staff were evaluated for latex allergy, using a complete questionnaire. Those suspected to have latex allergy underwent these tests: Eosinophils counting, measurement of serum total and latex specific IgE, latex skin prick test, latex and glove additives patch test. Results: From evaluated staff, 178 (34.8%) had a history of sensitivity to latex gloves, from which 59 persons underwent the tests voluntarily. According to the results of the tests, 13 (22%) had type I allergy to latex, 3 (5.1%) had type IV allergy to latex and 9 (15.3%) had both allergies. There were no significant relationship between latex allergy and age, sex, job, season, family and personal history of allergies. Significant relationship was found between type I allergy to latex and allergy to kitchen gloves and also between type IV allergy and allergy to other plastic clothing. Conclusion: Prevalence of latex allergy in this study is much higher than similar studies, which demands more evaluation to determine the contributing factors.

Atopic dermatitis (AD) is a chronic, inflammatory and pruritic skin disease with a prevalence of 10-20%. Recent studies suggested the effect of selenium on immunoregulation in AD. In this study we report 4 cases of atopic dermatitis according to Hafniin and Rajka criteria. Serum selenium levels were increased and serum total IgE were decreased in all patients. These results show that selenium is in the cells, therefore selenium could be a suitable and effective treatment. Further studies are required with increased subjects, different dosages and treatment duration to reach more definite results.
