Aim: The aim of this study is to assess radiographically the technical quality of root canal treatments (RCTs) performed by students at the Dakar Dental School. Materials and Methods: Out of 420 patients who had undergone RCTs, 501 teeth were randomly selected. Forty-eight teeth were excluded and the final sample involved 453 endodontically treated teeth. The length and the density of the root filling were evaluated for each filled root of each tooth. The presence of procedural errors was also evaluated. Descriptive statistics were used for expressing the frequencies of criteria and Chi-square test was used for comparing qualities of RCTs in terms of tooth locations, tooth types and academic level of students. The level of students, the significance level was set at 0.05. Results: From the 453 RCTs, 63.6% were acceptable. The rate of adequate RCTs was higher in the maxilla than in the mandible (P = 0.022) and in the premolars (75.5%) followed by the anterior teeth (69.7%) and the molars (49.2%) (P = 0.026). The difference was not significant in terms of level of students (P = 0.429). Inadequate density was found in 27.8%, whilst underfilling and overfilling were found in 26.5% and 7.3%, respectively. The frequency of procedural errors was 2%. Conclusion: The technical quality of RCTs performed by undergraduate students at the Dakar Dental School using step-back preparation and cold lateral condensation was classified as acceptable in 63.6% of the cases.
