【摘要】：根管治疗是牙髓病和根尖周病的主要治疗手段,而根管治疗成功与否很大程度上取决于根管预备的质量。在根管预备之前,首先要设计良好的髓腔入口并建立连续光滑的根管疏通通道,这个过程即为根管的初步预备。根管初步预备使清洁和成形根管的器械能够顺畅进入根管,可避免器械分离,为此专门用于建立根管光滑通道的器械应运而生。当下,根管初步预备器械凭借其独特的作用和良好的成形能力发展较为迅速,本文就根管初步预备器械的发展现状作一综述,旨在给牙髓病和根尖周病的治疗提供一些建设性的建议。
[Abstract]:Root canal therapy is the main treatment of pulp disease and periapical disease, and the success of root canal treatment depends on the quality of root canal preparation to a great extent, before root canal preparation. First of all, we should design a good pulp cavity entrance and establish a continuous smooth root canal dredging channel. This process is the initial preparation of the root canal. The initial preparation of the root canal enables clean and shaping instruments to enter the root canal smoothly. It can avoid the separation of instruments. For this reason, the instruments used specifically for the establishment of smooth channels of root canals came into being. At present, the primary instruments for root canal preparation have developed rapidly by virtue of their unique role and good forming ability. This article reviews the development of primary root canal preparation instruments in order to provide some constructive suggestions for the treatment of pulp disease and periapical disease.
