根尖孔外根面细菌生物膜的形成与难治性根尖周炎有关。然而，除了根外生物膜之外，还有其他几个因素会导致牙髓失败。本研究的目的是确定在日本的一般做法根管治疗失败的原因。通过检查2009年4月至2013年3月的病历，选择了由全科医生诊断为难治性根尖周炎并要求在大坂大学牙科医院进行牙髓治疗的患者。根管治疗失败的原因进行了鉴定。共选择103颗牙齿，76颗牙齿完成根管治疗。18颗牙齿需要拔牙后或没有牙髓治疗。六颗牙齿需要根管治疗后根尖切除术。一颗牙齿需要半切。一颗牙齿需要有意再植。1颗牙需粘连再植。治疗失败的主要原因是根尖开放（24颗）、穿孔（18颗）和根折（13颗）。在六颗需要根尖切除术或拔牙的根尖开放牙齿中，根外生物膜可能与牙髓失败有关。大多数根管治疗病例被全科医生诊断为难治性根尖周炎，而不是根外生物膜的任何其他因素的影响。本文的在线版本（10.1186/s12903-018-0530-6）包含补充材料，可供授权用户使用。
Bacterial biofilms that develop on root surfaces outside apical foramens have been found to be associated with refractory periapical periodontitis. However, several other factors cause endodontic failures apart from extraradicular biofilms. The aim of this study was to identify the factors causing endodontic failures in general practices in Japan. Patients diagnosed as having refractory periapical periodontitis by general practitioners and who requested endodontic treatment at Osaka University Dental Hospital were selected by checking medical records from April 2009 to March 2013. Factors causing endodontic failures were identified. A total of 103 teeth were selected, and 76 teeth completed root-canal treatment. Tooth extractions were required for 18 teeth after or without endodontic treatment. Six teeth required apicoectomy after endodontic treatment. One tooth needed hemisection. One tooth needed intentional replantation. One tooth needed adhesion and replantation. The main causes of treatment failure were open apices (24 teeth), perforation (18 teeth), and root fracture (13 teeth). In six teeth with open apices that required apicoectomy or extraction, extraradicular biofilms may have been related to endodontic failure. Most endodontic cases diagnosed with refractory periapical periodontitis by general practitioners were compromised by any other factors rather than extraradicular biofilms.
