Objective: To analyze the length of root canal fillings in endodontic treatments performed by undergraduate students at the Faculty of Dentistry at Finis Terrae University in 2022. Methodology: Observational, descriptive, and cross-sectional study, in which control radiographs of endodontic treatments performed by undergraduate students of the Faculty of Dentistry of Finis Terrae University in 2022 were collected through information obtained in a data collection sheet. The radiographs were analyzed using the Planmeca Romexis ® Viewer program and the obturation length was classified according to the criteria described by Barrieshi-Nusair. Then, the obturation length was described according to the following variables: tooth type, location in the oral cavity and the school year of the students. The analysis was performed using the statistical program SPSS. Results: A total of 104 endodontic canals were analyzed, of which 88.5% obtained an acceptable length filling, 6.7% overfilled and 4.8% underfilled. Regarding the school year of the students, in 4th year, 77.8% of endodontic treatments with adequate obturation length were found; in 5th, 89.4%; and in 6th, 90%. In mandibular tooth, 89.3% were acceptable; in the maxillary tooth, 88.2%. In the incisor group, 83.3% obtained an acceptable length filling, 100% in canines and 89.1% in premolars. Conclusions: The results obtained in the study were like others found in Chile, higher than some described in the Middle East and lower or like those found in Europe. In all the variables, the percentage of adequate obturation length was higher (77.8% for 4th, 89.4% for 5th, 90% for 6th, 89.3% for lower jaw, 88.2% for upper jaw, 83.3% for incisors, 100% for canines and 89.1% for premolars). This percentage of adequate treatments may be due, among other factors, to the use of the electronic apical locator and the support of specialists during undergraduate training and the execution of endodontic treatment.
