怎样提高根管治疗的成功率（How to improve the success rate of root canal therapy） Irreversible pulpitis occurs when bacterial infection through various channels into the pulp system, inflammation from serous inflammation development into local suppurative inflammation necrosis of all the bacteria through the apical pore diffusion, leading to inflammatory exudate, edema and damage to periapical tissues. The pathological process is interrupted due to root canal treatment operation intervention. From the point of view of etiology, many causes of root canal treatment failure can be classified into two categories: the first is microbial etiology. When root canal therapy fails to prevent the spread of bacteria or re - contamination in the short term, the disease continues to develop from the interruption, indicating a failure of treatment. It can also explain why the root canal treatment rate of infection is lower than that of non infected root canals. The second is a non microbial etiology, mainly in cases of failure after high quality root canal treatment. The purpose of this paper is starting from the first factor, discuss how to improve all aspects of root canal treatment, especially a detailed analysis of the operation process, to improve the quality of treatment, improve the success rate of root canal therapy. Some of them involve quality evaluation criteria. The analysis of the second factors is not included in this article. For root canal treatment, whether the three steps in the traditional idea that the root canal preparation, root canal disinfection and root canal filling, or modern concept advocated by the large taper, lateral or vertical pressure, just from the treatment process, in fact, is a surgical debridement process. Therefore, the root canal system was thoroughly clean is very important, should be regarded as the foundation of the entire treatment process. Closure of the root canal system with filling material is also critical when filling in the root canal followin
