| 摘 要： | 目的 探讨根管预备后残留细菌对根管治疗预后的影响。方法 选取50颗患慢性根尖周炎的单根管牙,分为实验组和对照组。实验组21颗患牙采用逐步后退法及超声冲洗预备根管,根管预备后取样做细菌培养, 立即充填根管,一次性完成根管治疗。对照组采用常规根管治疗方法治疗。根管治疗后6个月、1年及2年复查。结果 ①两组患牙根管治疗预后无明显差异。②实验组患牙根管预备后残余细菌与根管治疗预后无明显关系。 ③患牙术后疼痛与根充情况和术前症状无明显关系。结论 近期观察见经过彻底的根管预备,根管内微量残余细菌对根管治疗预后无明显影响。

| Abstract: | OBJECTIVE: To study the effect of the left bacteria on the root canal therapy. METHODS: 50 single-rooted teeth with chronic apical periodontitis were divided into two groups, one was instrumented with step-back technique and 2.5%NaOCl ultrasonic irrigation for 3 min, then filled with Thermafil. Samples were taken after instrumentation to culture. The other was treated with traditional RCT at three visits. RESULTS: In 24 months the apical radiolucency were greatly reduced in all cases. There weren't significant relationship among the postoperative pain and the left bacteria, the degree of the obturation or the pre-operative symptoms (P > 0.05). CONCLUSION: The effect of left bacteria in root canal filled with Thermafil wasn't observed. |
