近来研究证实,口腔苔藓样反应(OLR)可发生于与汞合金直接接触的口腔粘膜,用其它材料替换汞合金后,OLR可临床愈合。但缺乏长期研究。 材料和方法 49位患者,男性10例,女性39例,平均年龄52岁。OLR诊断标准:口腔内存在花边状、微突出的网状或丘疹状的白色损害或Wickham纹,病程超过3月。分为两组,Ⅰ组30例,病损局限于与汞合金接触的部位;Ⅱ组19例,病损超出接触区。记录修复体和病损程度,病损部位活检,做皮肤斑贴试验,待伤口
Recent studies have confirmed that OLR can occur in oral mucosa that is in direct contact with the amalgam, and that OLR can be clinically healed after the amalgam has been replaced with other materials. But lack of long-term research. Materials and Methods 49 patients, 10 males and 39 females, mean age 52 years. OLR diagnostic criteria: there are lace-shaped mouth, slightly protruding reticular or papular white lesions or Wickham pattern, the duration of more than March. Divided into two groups, Ⅰ group of 30 cases, the lesion confined to contact with the amalgam sites; Ⅱ group of 19 patients, lesions beyond the contact area. Record the degree of restoration and lesions, lesion site biopsy, skin patch test done until the wound
