Abstract
Introduction: Occupational allergic con- tact sensitization is common in dental personnel. Some of the most common occupational allergens in dental practi- ce are some formaldehyde-releasers, formaldehyde and glutaraldehyde. Aim: The aim of the present study was to evaluate the rate of contact sensitization to formaldehyde, quater- nium-15, imidazolidinyl urea, diazolidinyl urea, and to glutaraldehyde in students of dental medicine and dental patients. Material and methods: A total of 50 partici- pants were included in the study: 40 students of dental medicine exposed to formaldehyde-releasers, formal- dehyde and glutaraldehyde during the course of their education; 10 dental patients without occupational exposure to the latter substances served as a control group. All of them were patch-tested with the studied allergens. Results: The sensitization rate to formaldehyde was significantly higher in the group of dental patients if compared to the one of dental students ( 2 = 5.37; p =

Occupational allergic contact sensitization is common in dental personnel
We consider the importance of exposure to diazolidinyl urea, quaternium-15, imidazolidinyl urea and glutaraldehyde during the course of practical education in dentistry for the onset of sensitization
Occupational allergic contact sensitization is common in dental personnel, since in their daily activities they are exposed to the numerous chemical agents
Summary
Occupational allergic contact sensitization is common in dental personnel. Occupational allergic contact sensitization is common in dental personnel, since in their daily activities they are exposed to the numerous chemical agents. Preservatives were identified as the most common cosmetic contact allergens in several recent studies [5, 6], but they are applied in various materials used in everyday dental practice as well. They can be classified into three broad categories: antimicrobials, antioxidants, and ultraviolet light absorbers. The antimicrobial agents can be further divided into formaldehyde preservatives, formaldehyde-releasers, and non-formaldehyde-releasing preservatives
