“…Poor technical quality of root fillings has also been reported in many studies that evaluated the performance of students when using hand files (8)(9)(10)(11). Rafeek et al (11) found that the percentage of "acceptable" root fillings was as low as 10.9%, which was close to the 13% reported previously (10).…”

AimTo determine whether final-year undergraduate dental students achieved better shaping outcomes using the new ProTaper Next system (PTN) to prepare root canals for the first time compared with the existing ProTaper Universal system (PTU) on which they had trained. A secondary aim was to explore the attitudes and preferences of the students to both systems. Materials and MethodsForty students prepared one simulated S-shaped canal using PTN and another with PTU.Images of the canals were saved before and after preparation, and the outcomes assessed included the formation of aberrations and the amount of resin removed at specific points along the canal length. Student opinions relating to PTN and PTU were collected via a questionnaire completed immediately after using the systems. For statistical analysis, the McNemar test was used to compare the incidence of aberrations, and a paired t-test was used to analyse the width measurements. Responses to the questionnaire were analysed using frequencies. Thus, McNemar's test was used for paired binary data and the marginal homogeneity test for categorical data when more than two categories was used. Finally, the overall preferences (either PTN or PTU) were analyzed using the sign / binomial test, which is a standard statistical test that allows us to determine if the proportion preferring one or the other is equal or not. ResultsCanal ledges were formed in 30% of the canals prepared with PTU, whereas no ledges were formed with PTN (P < 0.001). A middle constriction, a form of canal aberration, was created by both systems, although it occurred significantly (P = 0.006) more often with PTN. The "number of files" was judged by students to be significantly higher (P < 0.001) for PTU compared to PTN. Even though using PTN for the first time, students were more likely to recommend the system to other students for preparing S-shaped canals than PTU (P = 0.018), and preferred to use PTN in the future (P < 0.001). ConclusionsThe students who had previous experience with the use of PTU were able to produce comparable shaping outcomes when they used PTN for the first time. For preparation of Sshaped canals, the students preferred PTN over PTU in terms of the number of files and would prefer to use it in future.

Aim. 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. Materials and Methods. 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. Results. 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%). Conclusions. Overall, the technical quality of root canal fillings performed by undergraduate students was satisfactory.

This study evaluated the technical quality of root canal treatment (RCT) and detected iatrogenic errors in an undergraduate dental clinic at the College of Dentistry, Taibah University, Saudi Arabia. Dental records of 280 patients who received RCT between 2013 and 2016 undertaken by dental students were investigated by retrospective chart review. Root canal obturation was evaluated on the basis of the length of obturation being ≤2 mm from the radiographic apex, with uniform radiodensity and good adaptation to root canal walls. Inadequate root canal obturation included cases containing procedural errors such as furcal perforation, ledge, canal transportation, strip perforation, root perforation, instrument separation, voids in the obturation, or underfilling or overfilling of the obturation. In 193 (68.9%) teeth, RCT was adequate and without procedural errors. However, in 87 (31.1%) teeth, RCT was inadequate and contained procedural errors. The frequency of procedural errors in the entire sample was 31.1% as follows: underfilling, 49.9%; overfilling, 24.1%; voids, 12.6%; broken instruments, 9.2%; apical perforation, 2.3%; and root canal transportation, 2.3%. There were no significant differences (p > 0.05) in the type or frequency of procedural errors between the fourth- and fifth-year students. Lower molars (43.1%) and upper incisors (19.2%) exhibited the highest and lowest frequencies of procedural errors, respectively. The technical quality of RCT performed by undergraduate dental students was classified as ‘adequate’ in 68.9% of the cases. There is a need for improvement in the training of students at the preclinical and clinical levels.
