目的通过对下颌第二磨牙X线术前片诊断C形根管准确率的研究,以期给临床医师提供一定的参考。方法选择2006-2009年我院牙体牙髓科门诊就诊的132例患者的134颗因急慢性牙髓炎或根尖周炎需作根管治疗的下颌第二磨牙,均为经根管治疗后,由经治医师根据探查,术前片,诊断丝片,术后片的结果,诊断为C形根管者。由工作十年以上富有工作经验的牙体牙髓专业医师10人,随机分为2组。A组仅通过术前片盲法判断及记录判断结果。B组通过每一患者完整病例资料盲法判断及记录判断结果。结果仅通过术前片诊断C形根管准确率为77.61%。结论术前X线片对下颌第二磨牙C形根管诊断的准确率高达77.61%,仔细阅读术前X线片,可以为临床工作提供重要依据,正确指导临床医疗工作。
Objective To study the accuracy of C-shaped root canal diagnosis of premolar X-ray of mandibular second molars in order to provide clinicians some reference. Methods A total of 134 mandibular second molars (132 mandibular second molar for acute or chronic pulpitis or periapical periodontitis) were enrolled in this study. Of the 132 patients treated in our dental pulp clinic during 2006-2009, By the physician based on exploration, preoperative films, diagnostic films, the results of postoperative films, the diagnosis of C-shaped root canal who. From the work of more than 10 years of work experience in dental pulp 10 professional physicians, were randomly divided into two groups. Group A only through preoperative film blind judgment and record the judgment results. Group B passed the blind judgment of each patient’s complete case data and recorded the judgment result. Results The accuracy of C-shaped root canal diagnosis by preoperative slice was 77.61%. Conclusions The accuracy of preoperative X - ray diagnosis of C - shaped root canal in the second molar of the mandible is as high as 77.61%. A careful reading of the preoperative X - ray can provide an important basis for clinical work and guide the clinical medical work correctly.
