自1985年6月我们共观察并治疗了流电作用引起口腔粘膜苔藓样病变11例,其中3例未复查,1例观察时间短,其余病例均在去除口腔内金属修复体后1—5个月内病变全部消失或好转。其中女性7例,男性4例,年龄在22岁～54岁。发病时间:在银汞充填后10天～5个月,在相应颊粘膜出现白色病变,这些口腔粘膜白色病变临床上象一个白斑,并且直径不小于5mm、不能用钝的器械擦掉,并没有一种明确的分类,而扁平苔藓在病损则有典型的wickham氏条纹,组织学上出现过度角化,上皮萎缩基底层液化变性,基底膜增宽,结缔组织中出现淋巴渗出。
Since June 1985, we observed and treated 11 cases of oral mucosal moss-like lesions caused by galvanic currents, of which 3 cases were not reviewed and 1 case was short. The remaining cases were removed 1-5 times after oral metal restoration All lesions disappeared or improved over the month. Among them, there are 7 females and 4 males, aged from 22 to 54 years old. Onset time: 10 days to 5 months after the amalgam filling, white lesions appear in the corresponding buccal mucosa, white lesions of these oral mucosa clinically as a white spot, and the diameter of not less than 5mm, can not be erased with a blunt instrument, and not A clear classification, and lichen planus lesions in the typical Wickham's streak, histological hyperkeratosis, epithelial atrophy basal liquefaction, basement membrane widening, lymphoid exudate in connective tissue.
