When patients have persistent oral complaints, it is important to consider allergic contact dermatitis to dental components. We present 3 cases seen at the Ottawa Hospital Patch Test Clinic between 2007 and 2009 with persistent oral lesions. Mercury, methacrylate, and beryllium were found to be the responsible allergens after patch testing. Of note, our case is the fourth reported dental contact dermatitis case to beryllium. Subsequently, a literature review and an examination of reported cases and management strategies were done. There is debate over the necessity of changing dental work after a positive patch-test result. We conclude that it is necessary to do your best to uncover all of the materials used in dental work. Often, material safety sheets do not include all allergens present in products. We advocate that if a positive reaction is found and deemed relevant, then appropriate replacement of the offending agent should be recommended.
当患者出现持续性口腔症状时，重要的是要考虑到对牙科部件的过敏接触性皮炎。我们报告了 3 例在渥太华医院斑贴试验诊所 2007 年至 2009 年间就诊的持续性口腔病变患者。经斑贴试验后发现汞、甲基丙烯酸酯和铍是致病过敏原。值得注意的是，我们的病例是第四例报告的铍致牙科接触性皮炎病例。随后，对文献进行了回顾，并对报告的病例和管理策略进行了检查。对于阳性斑贴试验结果后是否有必要更换牙科工作存在争议。我们的结论是，有必要尽最大努力找出牙科工作中使用的所有材料。通常，材料安全数据表并不包括产品中存在的所有过敏原。我们主张，如果发现阳性反应并认为相关，则应建议适当更换有问题的药物。
