ABSTRACT
OBJECTIVES:
The aim of this study has been to evaluate the rate of contact sensitization to some rubber allergens and to bisphenol A (BPA) amongst students of dental medicine and dental patients. MATERIAL ANDMETHODS:
A total of 50 participants were included in the study 40 students of dental medicine exposed to the studied rubber allergens and BPA-based dental materials 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 rubber allergens and bisphenol A.RESULTS:
Highest was the sensitizing action of carba mix, followed by benzoyl peroxide and mercapto mix. The sensitization rate for carba mix was significantly higher for dental students as well as for the whole studied population, if compared to the one for thiuram mix (Chi2 = 12.9, p < 0.001; Chi2 = 13.9, p < 0.001), bisphenol A (Chi2 = 8.9, p < 0.001; Chi2 = 11.9, p < 0.001), toluenesulfonamide formaldehyde resin (Chi2 = 10.7, p < 0.001; Chi2 = 13.9, p < 0.001) and benzoyl peroxide (Chi2 = 4.7, p = 0.03; Chi2 = 5.8, p = 0.016), and for dental patients, if compared to the one for mercapto mix (Chi2 = 7.07, p = 0.008). Concomitant positive skin patch-test reactions to carba mix and to benzoyl peroxide, and to all the studied allergens were established.CONCLUSIONS:
Carba mix could be outlined as a sensitizer of paramount importance for dental students as well as for dental patients. Benzoyl peroxide was the second ranked sensitizer for dental students. Positive skin patch-test reactions to bisphenol A and toluenesulfonamide formaldehyde resin were established only among the group of dental students.
