The aim of this audit was to evaluate the technical quality of undergraduate de novo endodontic competence cases in the Dublin Dental University Hospital (DDUH) compared to European standards.
A radiographic analysis of the number of canals in student 'competence' cases (completed 2009-2010) that met the accepted technical criteria for an ideal root canal treatment was carried out. The benchmark was formulated using accepted European guidelines. Several technical factors were analysed including the apical extent of obturation (within 2mm of radiographic apex), the presence of voids, technical errors and the presence of untreated roots. One hundred and nineteen root canals were initially selected in 78 teeth; however, five teeth were excluded from analysis as the postoperative radiograph was either missing or not diagnostic.
Single-rooted teeth demonstrated voids in 36% of root fillings, and 69% were filled to within 2mm of the apex and there were no detectable technical deficiencies. Multi-rooted teeth demonstrated voids in 38% of root fillings; 60% were filled to within 2mm and 94% of canals demonstrated no deviation from the original canal. Combined results demonstrated that 49% of all the single-rooted teeth and 17% of all the multi-rooted teeth were acceptable within the technical parameters identified in the guidelines.
Analysis of individual technical criteria revealed areas in which the quality was acceptable and others in which it could be improved. Although the overall results appeared poor, they were similar to previous studies of the technical quality of undergraduate root canal treatment.
本次审核旨在将都柏林牙科大学医院（DDUH）本科新生牙髓病治疗能力病例的技术质量与欧洲标准进行比较评估。
对符合理想根管治疗公认技术标准的学生“能力”病例（2009 - 2010年完成）的根管数量进行影像学分析。使用公认的欧洲指南制定基准。分析了几个技术因素，包括充填的根尖范围（在影像学根尖2mm范围内）、空隙的存在、技术错误以及未治疗牙根的存在。最初在78颗牙齿中选取了119个根管；然而，有5颗牙齿被排除在分析之外，因为术后X光片缺失或无法诊断。
单根牙的根管充填中有36%存在空隙，69%的根管充填至根尖2mm范围内，且未发现可检测到的技术缺陷。多根牙的根管充填中有38%存在空隙；60%的根管充填至根尖2mm范围内，94%的根管未偏离原始根管。综合结果表明，在指南确定的技术参数范围内，所有单根牙中有49%、所有多根牙中有17%是可接受的。
对各项技术标准的分析揭示了质量可接受的领域以及可改进的领域。尽管总体结果似乎不佳，但与之前关于本科根管治疗技术质量的研究结果相似。
