Oral lichenoid lesions related to contact are defined as oral-cavity eruptions with an identifiable etiology, and are clinically and histologically similar to oral lichen planus. Within this group are found oral lichenoid lesions related to contact with dental materials (OLLC), the most common being those related to silver amalgam. Currently, it remains difficult to diagnose these lesions due to the clinical and histopathological similarity with oral lichen planus and other oral mucosa lesions of lichenoid characteristics. In the present paper, we carry out an updated review of the tests for, and the different characteristics of OLLC, which may aid the diagnosis. For this review, we made searches in the Pubmed(R) and Cochrane(R) databases. Among the literature we found several published papers, from which we have used review papers, case papers, cohort studies, case and control studies, and a meta-analysis study. After carrying out this review, we can conclude that the diagnosis of these lesions is still difficult and controversial. However, there are different aspects in the clinical presentation, pathological study and results obtained when replacing suspect materials, which, when taken together, may be useful when establishing the final diagnosis of OLLC.
与接触相关的口腔扁平苔藓样病变被定义为具有可识别病因的口腔腔发作，在临床上和组织学上与口腔扁平苔藓相似。在这一组中发现了与牙科材料接触相关的口腔扁平苔藓样病变（OLLC），最常见的是与银汞合金相关的病变。目前，由于与口腔扁平苔藓和其他具有苔藓样特征的口腔黏膜病变在临床和组织病理学上的相似性，这些病变的诊断仍然很困难。在本文中，我们对 OLLC 的检测和不同特征进行了更新的回顾，这可能有助于诊断。为此，我们在 Pubmed(R)和 Cochrane(R)数据库中进行了搜索。在我们找到的文献中，有几篇已发表的论文，我们从中使用了综述论文、病例论文、队列研究、病例对照研究和荟萃分析研究。经过回顾，我们可以得出结论，这些病变的诊断仍然很困难，存在争议。然而，在临床表现、病理研究和可疑材料替代后的结果方面存在不同的方面，这些方面结合起来，在确定 OLLC 的最终诊断时可能是有用的。
