To radiographically evaluate the technical quality of root canal treatment performed by undergraduate dental students and compare the findings with other institution's work.
A retrospective, cross-sectional study was conducted at the Academy Dental Teaching Hospital involving postoperative periapical radiographs of patients who were endodontically treated by batch #14 undergraduate dental students of final year (2013-2014) from UMST, Sudan. The total number of the students was 21, while periapical radiographs fulfilling the required criteria were 173. The radiographs of each case were evaluated in terms of length, density, and taper of the root canal filling. Procedural errors such as presence of a ledge, perforation, and a separated instrument were also recorded. Chi-square test was used to determine statistically significant differences between variables, with the level of significance set at ≤ 0.05.
The overall quality of performed root canal treatment was adequate in almost half (55.5%) of the evaluated teeth. The length and taper of the root canal filling were found to be significantly associated with maxillary and mandibular posterior teeth with = 0.018 and 0.006, respectively. No associations were found between the density and presence of separated instrument in the maxillary and mandibular posterior teeth, = 0.314 and 0.480, respectively.
The radiographic quality of root canal treatment performed by undergraduate students of batch #14 UMST was acceptable in 55.5% of the cases. Special emphasis must be placed on the educational methods and training of students for providing root canal treatment on molar teeth.
通过影像学评估牙科本科学生进行根管治疗的技术质量，并将结果与其他机构的工作进行比较。
在牙科学院教学医院进行了一项回顾性横断面研究，纳入了苏丹喀土穆大学牙科学院2013 - 2014学年最后一年的14班本科牙科学生进行牙髓治疗的患者的术后根尖片。学生总数为21名，符合要求标准的根尖片有173张。对每个病例的根尖片从根管充填的长度、密度和锥度方面进行评估。还记录了诸如台阶、穿孔和器械分离等操作失误。采用卡方检验确定变量之间的统计学显著差异，显著性水平设定为≤0.05。
在几乎一半（55.5%）的评估牙齿中，所进行的根管治疗总体质量是足够的。发现根管充填的长度和锥度与上颌和下颌后牙显著相关，分别为P = 0.018和0.006。在上颌和下颌后牙中，未发现密度与器械分离之间的关联，分别为P = 0.314和0.480。
喀土穆大学14班本科学生进行的根管治疗的影像学质量在55.5%的病例中是可接受的。必须特别强调对学生进行磨牙根管治疗的教育方法和培训。
