不同龈下冲洗方式对合并梅毒的牙周炎患者的治疗效果的对比评价

目的研究不同龈下冲洗方式对合并梅毒的牙周炎患者的治疗效果。方法选择从2011年9月～2012年9月于我院治疗的10例合并梅毒的牙周炎患者（含50颗患牙），按照随机数字表法分为实验组和对照组各5例。对照组采用超声龈下刮治后，采用含有0．2％甲硝唑液的传统冲洗器对患牙进行冲洗。实验组采用超声龈下刮治，同步采用0．2％甲硝唑液进行冲洗处理，分别记录治疗前、治疗7d后的菌斑指数（PL）、附着丧失（AL）、探诊深度（PD）、牙龈出血指数（SBI）四项指标，分别比较两组治疗前后牙周各指标的变化以及两组间治疗前后牙周各指标的差异。结果治疗7d后，实验组和对照组PL、SBI均显著降低；实验组治疗后PL、AL、PD、SBI的降低程度明显优于对照组，差异有统计学意义（P〈0．05）。结论超声龈下刮治同步药物冲洗治疗合并梅毒的牙周炎的临床效果良好，明显优于传统超声龈下刮治后冲洗器给药的冲洗方式。

The treatment effect of different subgingival flushing in extrasyphilitic periodontitis

Objective To study the clinical effects of the different subgingival flushing in extrasyphilitic syphilitic periodontitis patients. Methods Ten cases extrasyphilitic syphilitic periodontitis patients from September 2011 to September 2012 were randomly divided into experimental group and control group, 5 cases in each group.The control group were used ultrasonic subgingival scaling,then traditional washing containing 0.2% metronidazole rinse treatment were used to them.The experimental group were used ultrasonic subgingival scaling, synchronization Q：2% metronidazole liquid flush handle.Before treatment and after 7 days of treatment, plaque index （PL）,attachment loss （AL）, probing depth （PD） ,gingival bleeding index （SBI） were recorded. Various indicators of periodontal changes in the two groups were compared before and after treatment, as well as differences between the two groups befo~＇e and after treatment, periodontal index. Results Seven days after the treatment, PL, SBI of the experimental group and the control group,were significantly reduced; after the treatment PL, AL, PD, SBI of the experimental group reduced significantly than the control group, the difference was statistically significant （P 〈 0.05）. Conclusion The clinical effect of ultrasound subgingival scaling synchronization washout the periodontitis treatment of syphilis is significantly better than conventional ultrasonic subgingival scaling.
