【摘要】目的：采用不同的根管冲洗、消毒药物治疗牙周牙髓联合病变,观察其疗效并与传统药物比较。方法：将68颗患牙随机分为实验组和对照组。在根管治疗中，实验组用替硝唑溶液超声荡洗，盐酸米诺环素消毒；对照组用次氯酸钠溶液超声荡洗，氢氧化钙消毒，两组患牙均用Protaper冠向下预备根管，热牙胶垂直加压充填，并且在根管治疗的同时行牙周系统治疗。对比观察两组患牙基线和牙周治疗后6周、12周的菌斑指数(PLI)、探诊出血指数(BI)、 牙周探诊深度(PD)和临床附着水平(CAL)四项临床指标以及12周后患牙治疗的有效率。结果：①两组患牙在治疗后6周及12周时的PLI、BI、PD、CAL均较基线时有改善(<0.01)，但6周和12周时各项指标之间无差异；②治疗6周后实验组的各项指标改善均优于对照组，差异有统计学意义(<0.05)，但12周后仅PD、CAL两项指标组间有统计学差异(<0.05)；③12周后两组的有效率无差异。结论：采用替硝唑进行根管冲洗、盐酸米诺环素消毒根管,对牙周牙髓联合病变的短期疗效优于次氯酸钠和氢氧化钙常规药物。

【Abstract】Objective: To compare the therapeutic effects of different root canal irrigants and disinfectants on combined periodontal-endodontic lesions. Methods: 68 teeth were randomly divided into the experimental and control group. In root canal therapy, the experimental group was treated under ultrasonic irrigation with tinidazole solution and disinfection with minocycline hydrochloride, whereas the control group was under ultrasonic irrigation with sodium hypochlorite solution and disinfection with calcium hydroxide. All teeth in two groups were therapyed under root canal preparation using the protaper instruments with crown-down techniques and given root canal obturation using warm gutta-percha vertical condensation technique.At the same time of root canal therapy, both groups were treated under systematic periodontal therapy. The plaque index(PLI), bleeding index (BI), probing depth (PD) and clinical attachment level (CAL) were observed at baseline and 6 weeks 、12 weeks after periodontal treatments. And treatment efficiency of two groups was evaluated after 12 weeks Results: ①After 6 weeks and 12 weeks, PLI、BI、PD and CAL of both groups had significantly improved compared with the baseline (p<0.01), However, there was no differences about these four indicators between 6 weeks and 12 weeks ......
