AIM
The aim of the present study was to evaluate radiographically the technical quality of root canal filling performed by postgraduate students with a new single-file Nickel-Titanium System (F6 Skytaper Komet) in clinical practice.
METHODS
Records of 74 patients who had received endodontic treatment by postgraduate students at the School of Dentistry, Faculty of Medicine, University of Pavia in the period between September 2015 and April 2016 were collected and examined: the final sample consisted 114 teeth and 204 root canals. The quality of endodontic treatment was evaluated by examining the length of the filling in relation to the radiographic apex, the density of the obturation according to the presence of voids and the taper of root canal filling. Chi-squared analysis was used to determine statistically significant differences between the technical quality of root fillings according to tooth's type, position and curvature.
RESULTS
The results showed that 75,49%, 82,84% and 90,69% of root filled canals had adequate length, density and taper respectively.
CONCLUSIONS
Overall, the technical quality of root canal fillings performed by postgraduates students was acceptable in 60,78% of the cases.
目的
本研究旨在通过影像学评估研究生在临床实践中使用新型单根镍钛系统（F6 Skytaper Komet）进行根管充填的技术质量。
方法
收集并检查了2015年9月至2016年4月期间在帕维亚大学医学院牙科学院由研究生进行牙髓治疗的74例患者的记录：最终样本包括114颗牙齿和204个根管。通过检查充填物相对于影像学根尖的长度、根据有无空隙评估充填的密度以及根管充填的锥度来评估牙髓治疗的质量。采用卡方分析来确定根据牙齿类型、位置和弯曲度的根管充填技术质量之间的统计学显著差异。
结果
结果显示，分别有75.49%、82.84%和90.69%的充填根管长度、密度和锥度合适。
结论
总体而言，60.78%的病例中研究生进行的根管充填技术质量是可接受的。
