对于老年牙隐裂伴窦道型慢性根尖周炎,临床上常规行氧化锌丁香油碘仿糊剂根管充填治疗,但术后出现的再感染可导致近60%的患者治疗失败。寻找理想的根管充填材料和方法,彻底封闭根管系统是研究者一直关注的问题。糊剂的使用是根尖封闭质量的关键。本文对70颗牙隐裂伴窦道型慢性根尖周炎采用Cortisomol及氧化锌丁香油碘仿糊剂两次性根管充填治疗,分析1年后的疗效。
For the elderly with occult sinusoidal periapical periodontitis, routine clinical zinc oxide clove oil iodoform paste root canal filling treatment, but postoperative re-infection can lead to nearly 60% of patients failed treatment. Looking for the ideal root canal filling materials and methods, the complete closure of the root canal system has been a researcher’s concern. The use of paste is the key to the apical sealing quality. In this paper, 70 teeth with occult sinusoidal chronic periapical periodontitis were treated with Cortisomol and zinc clove oil-iodoform paste twice. The curative effect after 1 year was analyzed.
