The aim of this study was to evaluate the radiographic technical quality of endodontic treatment performed by undergraduate students at the School of Dentistry, Faculty of Medicine, University of Novi Sad, Serbia.
Electronic records of 220 patients treated by final-year undergraduate students during the school year 2011/2012 were examined, and the final sample consisted of 212 patients, 322 teeth, and 565 root canals. The criteria for overall radiographic adequacy of root canal fillings were defined as the presence of adequate length and density and absence of iatrogenic errors (ledge, fractured instrument, untreated canal, and apical transportation). Chi-square test was used to determine statistical significance between different parameters.
Adequate root canal fillings were found in 74.22% of the teeth. The percentage of root fillings with adequate length and density was 89.73% and 92.6%, respectively. Fractured instruments and ledges were present in 16 root canals (2.8%), while the presence of missed canal and apical transportation was observed in 2 cases, each (0.3%).
Overall, the technical quality of root canal fillings performed by undergraduate students was satisfactory.
本研究旨在评估塞尔维亚诺维萨德大学医学院牙科学院本科学生进行的牙髓治疗的影像学技术质量。
检查了2011/2012学年本科最后一年学生治疗的220例患者的电子记录，最终样本包括212例患者、322颗牙齿和565个根管。根管充填总体影像学充足的标准定义为长度和密度合适且无医源性错误（台阶、器械折断、未处理根管和根尖移位）。采用卡方检验确定不同参数之间的统计学显著性。
74.22%的牙齿根管充填合适。长度合适和密度合适的根管充填百分比分别为89.73%和92.6%。16个根管（2.8%）存在器械折断和台阶，而各有2例（0.3%）观察到存在遗漏根管和根尖移位。
总体而言，本科学生进行的根管充填技术质量令人满意。
