“…At the institution (Riyadh Colleges of Dentistry and Pharmacy), the students determine the working length using electronic apex locators and confirm it radiographically, and this may account for the relatively high percentages of acceptable length canal fillings. This result is in line with the findings of a recent study (Tchorz et al, 2014) that concluded that the early introduction of electronic apex locators during pre-clinical training improves the quality of root canals performed by undergraduate students in the clinical setting.…”

The aim of this study was to evaluate the outcomes of teaching endodontics to undergraduate students at Riyadh Colleges. This study was undertaken by assessing the technical quality of root canal obturation and the presence of procedural errors in root canal treatment cases performed by the final year dental students in clinics. All of the root canal treatment cases performed by the final year dental students in the 2nd semester of 2012 to 2013 were examined, with a total of 450 root canals from 241 teeth. The quality of root canal obturation was examined in relation to the length of the root filling based on the radiographic apex, the density of the obturation according to the presence of voids, and the taper of root canal fillings. The overall acceptable quality of the evaluated root canals was 36%. Of these canals, acceptable length, density, and taper were reported in 76.6, 46.4, and 73.8%, respectively. Overall, 9.3% of the treated root canals had procedural errors, and majority of these errors were found in canals of posterior mandibular teeth. Apical transportation was the most encountered error; it was found in 3.1% of the treated canals. The technical quality of the root canal treatments conducted by the students in this study was comparable to other studies. However, introducing new techniques and armamentaria might improve this quality.

Aim:To radiographically evaluate the technical quality of root canal treatment performed by undergraduate dental students and compare the findings with other institution's work.Materials and Methods:A retrospective, cross-sectional study was conducted at the Academy Dental Teaching Hospital involving postoperative periapical radiographs of patients who were endodontically treated by batch #14 undergraduate dental students of final year (2013–2014) from UMST, Sudan. The total number of the students was 21, while periapical radiographs fulfilling the required criteria were 173. The radiographs of each case were evaluated in terms of length, density, and taper of the root canal filling. Procedural errors such as presence of a ledge, perforation, and a separated instrument were also recorded. Chi-square test was used to determine statistically significant differences between variables, with the level of significance set at P ≤ 0.05.Results:The overall quality of performed root canal treatment was adequate in almost half (55.5%) of the evaluated teeth. The length and taper of the root canal filling were found to be significantly associated with maxillary and mandibular posterior teeth with P = 0.018 and 0.006, respectively. No associations were found between the density and presence of separated instrument in the maxillary and mandibular posterior teeth, P = 0.314 and 0.480, respectively.Conclusion:The radiographic quality of root canal treatment performed by undergraduate students of batch #14 UMST was acceptable in 55.5% of the cases. Special emphasis must be placed on the educational methods and training of students for providing root canal treatment on molar teeth.

Aim: To assess the root canal filling quality performed by general dental practitioners in Yemen through radiographic evaluation. Materials and Methods: Four hundred fifty-five digital panoramic radiographs were selected from the archive of the Dental Health Center in Sana'a, Yemen. The final sample consisted of 221 patients, 685 teeth, and 977 root canals. The criteria for overall radiographic adequacy of root canal fillings were defined as the presence of adequate length, density and taper, and absence of iatrogenic errors (ledges, transportations and perforations). Chi-square test was used to determine statistical significance between different parameters. Results: This study considered only radiographic criteria for evaluation of the root canal fillings. The percentage of root canal fillings with adequate length, density and taper was 30.8%, 29.6% and 20.7%, respectively. Considering the incidence of iatrogenic errors, perforations were present in 12 root canals (1.2%), while the presence of transportations was observed in 20 root canals (2.0%). However, ledges were no detected in any root canals. Conclusion: The root canal filling quality performed by general dental practitioners in Yemen is poor.

Evaluation of an improved endodontic teaching model: do preclinical exercises have an influence on the technical quality of root canal treatments?

Abstract: The application of an ERCLMD in combination with radiographs is more accurate to determine WL than radiographs alone. Students practiced the use of ERCLMDs with the new model and benefited from this experience when performing their first root canal treatments on patients.
