作者引用两个新的临床指标:需外科治疗的牙数(Tooth Status,TS_1)与治疗后保存的牙数(Teeth Saved,TS_2),结合牙周袋深度(PD)与上皮附着水平(AL)的改变来作为衡量牙周病治疗措施好坏的标准。材料和方法选择暗视野显微镜下螺旋体数量大于20％的33例成人牙周病患者。经牙周基础治疗后,随机分成两组,进行双盲试验。实验组15例,口服甲硝唑250mg每日三次,共一周;对照组18例,给予安慰剂。试验后4～6周、1年和2年分别记录TS_1,TS_2,PD和AL。
The authors cite two new clinical indicators: Tooth Status (TS_1) and Teeth Saved (TS_2), which combined PDL with epithelial attachment (AL) Change as a measure of the treatment of periodontal disease is good or bad standards. Materials and Methods 33 cases of adult periodontal disease with more than 20% of spirochetes under dark-field microscopy were selected. After periodontal basic treatment, were randomly divided into two groups, double-blind test. The experimental group of 15 cases, 250mg metronidazole orally three times a day for a total of one week; the control group of 18 patients given placebo. TS_1, TS_2, PD and AL were recorded 4 to 6 weeks, 1 year and 2 years after the test.
