不同充填技术根管充填的CBCT分析(体外研究)

摘要

简介:根管充填的作用是防止再感染，封闭根管间隙。许多根管充填技术已经发展起来，以实现根管系统的三维封闭。研究目的:评价三种不同的CBCT充填技术对根管充填质量的影响。材料与方法:取30颗拔除的人单根牙，采用ProTaper Next旋转系统确定工作长度、清洁及整形。根据闭孔技术将牙齿随机分为3组(n=10)。第一组采用侧侧压实技术进行根管充填。第二组采用单锥技术进行根管充填(ProTaper F3)。第三组采用菖蒲加杜仲胶墨盒充填根管。所有组使用的树脂基密封剂是相同的。结果:CBCT在根尖、正中、冠状面三个层面进行了评估。 The result showed that with lateral compaction and single cone technique voids present more at the middle and coronal third. With Calamus technique more voids at the coronal part. The comparison of the obturation techniques showed no significant differences between the three groups. Conclusion: from our result we can conclude that all the systems showed minimum voids at the apical part rather than the middle and coronal part. There was no significant difference between obturation techniques. There wasn’t any system showed obturation void-free.
