The aim of this study was to evaluate the technical quality of root canal treatment (RCT) performed by preclinical undergraduate dental students at the Dental College of Taibah University KSA.
In this study, 259 extracted teeth were treated endodontically by preclinical students of the College of Dentistry, Taibah University, KSA, from 2013 to 2015. The evaluation criteria were root canal obturation length, root canal obturation density (homogeneity), and root canal obturation taper. A specific score (0, 1, or 2) was assigned to each parameter.
Of 259 endodontically extracted teeth, 138 (53.3%) had RCT of unacceptable technical quality, 42 (16.2%) had treatment of slightly acceptable technical quality, 50 (19.3%) had treatment of acceptable technical quality, and 29 (11.2%) teeth had RCT of perfectly acceptable technical quality. There were no significant differences ( > 0.05) in the technical quality of root canal obturation among types of teeth.
The results of this study showed that there were varied levels of technical quality of root canal treatment performed by preclinical undergraduate dental students, and the outcome varied between unacceptable, slightly acceptable, acceptable, and perfectly acceptable. The unacceptable cases were the most common, representing more than half of all cases, and the perfectly acceptable cases were the least common. There is an urgent need to improve the endodontics teaching programmes in the College of Dentistry of Taibah University. This research should be repeated in the future to evaluate improvement in the performance of RCT by undergraduate dental students in Taibah University.
本研究旨在评估沙特阿拉伯王国泰巴赫大学牙科学院本科临床前牙科学生进行根管治疗（RCT）的技术质量。
在本研究中，2013年至2015年期间，沙特阿拉伯王国泰巴赫大学牙科学院的本科临床前学生对259颗拔除的牙齿进行了根管治疗。评估标准为根管充填长度、根管充填密度（均匀性）和根管充填锥度。每个参数都被赋予一个特定的分数（0、1或2）。
在259颗接受根管治疗的拔除牙齿中，138颗（53.3%）的根管治疗技术质量不可接受，42颗（16.2%）的治疗技术质量尚可接受，50颗（19.3%）的治疗技术质量可接受，29颗（11.2%）牙齿的根管治疗技术质量完全可接受。不同类型牙齿的根管充填技术质量之间无显著差异（>0.05）。
本研究结果表明，本科临床前牙科学生进行的根管治疗技术质量存在不同水平，结果在不可接受、尚可接受、可接受和完全可接受之间有所不同。不可接受的病例最为常见，占所有病例的一半以上，而完全可接受的病例最少见。迫切需要改进泰巴赫大学牙科学院的牙髓病学教学计划。未来应重复此项研究，以评估泰巴赫大学本科牙科学生根管治疗表现的改善情况。
