791 patients, among them 59 dental technicians and 732 other patients, were tested with the denture material series (DMS) recommended by the German Contact Dermatitis Research Group (DKG) in the hospitals of the Information Network of Departments of Dermatology (IVDK) between January 1990 and July 1993. Most frequently, positive reactions occurred to cadmium chloride in both groups. However, there was no evidence at all for relevance of these reactions. Benzoyl peroxide (BPO) ranked 2nd in patch test positivity. Although not statistically significant, reactions were more frequent in dental technicians, who might be exposed to BPO the in working environment. Methyl methacrylate (MMA) and triethylene glycol dimethacrylate (TEGDMA) were common sensitizers in dental technicians but not in other patients. This finding, too, has its explanation in the working process of manufacturing dental prostheses.
1990年1月至1993年7月期间，在德国皮肤科部门信息网络（IVDK）的医院中，对791名患者进行了测试，其中包括59名牙科技术人员和732名其他患者，使用德国接触性皮炎研究小组（DKG）推荐的假牙材料系列（DMS）。两组中最常见的阳性反应均为对氯化镉的反应。然而，没有任何证据表明这些反应具有相关性。过氧化苯甲酰（BPO）在斑贴试验阳性率中排名第二。虽然无统计学意义，但牙科技术人员中的反应更为频繁，他们可能在工作环境中接触到BPO。甲基丙烯酸甲酯（MMA）和二甲基丙烯酸三乙二醇酯（TEGDMA）是牙科技术人员中的常见致敏原，但在其他患者中并非如此。这一发现同样可以在假牙制造的工作过程中得到解释。
