The aim of this report is to present a clinical case of oral lichenoid lesions associated with amalgam restorations with the presence of desquamative gingivitis for a nine months follow up period.
The histopathologic characteristics and direct immunofluorescence were compatible with Oral Lichenoid Lesion (LLO). Diagnosis was based on a synthesis of all available information, including medical history, clinical examination, histopathology and the results of specific tests, such as the patch test, which confirmed allergy to thimerosal, an organic compound of mercury.
The replacement of amalgam restorations has brought improvements to the instrument, as evidenced by the disappearance of desquamative gingivitis, aspect erythematosus and erosive lesions. The fading does not complete the same, however, indicates the need to continue has been under continuous observation, the patient, having in view the possibility of the existence of an underlying lichen planus.
本报告旨在呈现一例与汞合金修复体相关的口腔苔藓样病变临床病例，并对其进行为期九个月的随访，观察其是否伴有剥脱性龈炎。
组织病理学特征和直接免疫荧光检查结果与口腔苔藓样病变（LLO）相符。诊断基于综合所有可用信息，包括病史、临床检查、组织病理学以及特定检测结果，如斑贴试验，该试验证实患者对硫柳汞（一种汞的有机化合物）过敏。
汞合金修复体的替换使病情有所改善，剥脱性龈炎、红斑和糜烂性病变消失即为明证。然而，症状并未完全消退，这表明鉴于可能存在潜在的扁平苔藓，仍需对患者持续进行观察。
