The aim of the present study was to evaluate the quality of root canal treatment performed by undergraduate dental students at the University of Khartoum. Assessment was by examination of periapical radiographs of completed endodontically treated teeth, performed by undergraduate dental students. A total of 166 postoperative periapical radiographs compromising 265 roots were included. The quality of endodontic treatment was examined in relation to the length of the root filling in relation to the radiographic apex, the density of the obturation according to presence of voids and the taper of root canal fillings. Adequate length of the root filling was found in 34.7% of the maxillary teeth and in 10.9% of mandibular teeth in this study. Adequate density was found in 38.87% of maxillary and 16.98% of mandibular teeth and appropriate taper was found in 40% of maxillary and 16.6% of mandibular teeth. Overall 24.2% in all evaluated teeth were found to have a root filling of an acceptable quality. This result may be because of insufficient preclinical endodontic training of the students' operators or because of the introduction of students to endodontic clinical practice late in their program.
本研究的目的是评估喀土穆大学牙科本科生进行根管治疗的质量。评估方式是由牙科本科生对已完成牙髓治疗的牙齿的根尖片进行检查。总共纳入了166张术后根尖片，涉及265个牙根。从根管充填长度与根尖片根尖的关系、根据有无空隙判断的充填密度以及根管充填的锥度等方面对根管治疗质量进行了检查。在本研究中，发现上颌牙根管充填长度合适的占34.7%，下颌牙占10.9%。上颌牙充填密度合适的占38.87%，下颌牙占16.98%；上颌牙锥度合适的占40%，下颌牙占16.6%。总体而言，在所有评估的牙齿中，24.2%的牙齿根管充填质量可接受。这一结果可能是由于学生操作者临床前牙髓治疗培训不足，或者是因为学生在课程后期才开始牙髓临床实践。
