Introduction and objective: There are still few studies that accurately address endodontic success and which failures actually impact the endodontic treatment outcome. Determine success rate and predictive factors for successful endodontic treatment and retreatment by undergraduate students of the same learning level. Materials and methods: The preservation records (12 months) of the endodontic treatments performed in the Faculty of Dentistry of Pelotas were verified, indicating the success or failure of the treatment. Predictive variables in the outcome of successful endodontic treatment or retreatment were: tooth, number of channels, dental crown, symptoms, pulp diagnosis, radiographic periapical index. The treatment-related variables were: instrumentation technique, number of sessions and apical instrumentation limit. Results: 136 endodontic treatments were performed with a follow-up of at least 12 months. The evaluation showed that endodontic success was influenced by the number of sessions (P = 0.015), initial diagnosis and dental group (P = 0.014). It was also observed that the higher the initial radiographic periapical index, the worse the endodontic prognosis (P < 0.001). Conclusion: The success rate of endodontic treatment was 96.7% for cases of vital pulp, 87.5% for cases of pulp necrosis and 92.9% for retreatments. These indices were influenced by type tooth, initial diagnosis, initial radiographic periapical index and the number of visits used in the treatment.
