长期以来,人们普遍认为如果认真遵守根管治疗术的三个基本原则,最后的治疗结果肯定是成功的,这三个基本原则是:1.根管的彻底清理,2.根管的消毒,3.根管的完全充填。如果偏离了这些原则,几乎肯定会引起根管治疗失败。根管充填历来被认为是根管治疗最重要的部分,假定根管经过很好地清理和消毒,完全充填应当产生良好的结果。这一结论是以下列理论为基础的:1.如果根管充填不好,在根充料和根管壁之间的空隙可能藏有细菌和组织碎片,它们将成为尖周组织刺激物。2.假如允许空隙存在于根管根尖
For a long time, it is generally accepted that the final outcome of treatment is certainly successful if the three basic principles of root canal therapy are meticulously followed: 1. thorough root canal clean-up, 2. root canal disinfection, 3. Complete filling of the root canal. Deviations from these principles will almost certainly lead to failure of root canal treatment. Root canal filling has always been considered the most important part of root canal treatment, assuming that the root canal is well cleaned and sterilized, full filling should produce good results. This conclusion is based on the following theories: 1. If the root canal filling is not good, the space between the root canal filling and the root canal wall may harbor bacterial and tissue fragments that will become perineal tissue irritants. 2. If the gap is allowed to exist in the apical root canal
