Objective: The aim of the study was to assessment of technical quality of 9562 endodontic cases treated by heterogeneous groups with different clinical experience. Material and methods: This retrospective study reviewed the dental records of 8590 patients (9562 endodontic cases and 13203 root canals including 3340 retreatment root canals) treated by fourth-year undergraduates, fifth-year undergraduates, endodontic program students, and endodontic specialists between December 2017 and December 2018 at the Department of Endodontics of Necmettin Erbakan University Faculty of Dentistry in Konya. The length, density, and taper of root fillings, the acceptable technical quality of the root filling criteria, and the presence of procedural errors, were recorded. Chi-square tests with a significance level at p=0.05 were used for statistical analysis. Results: Acceptable root fillings were found in 71.5% of endodontic cases. Clinical experience showed statistical differences in the root filling quality among fourth-year undergraduates, fifth-year undergraduates, endodontic program students, and specialists (52, 63.1, 77.9 and 86.5% respectively). Fractured instruments and missed canals were noted in 9.8% and 0.57% of cases treated by endodontic program students significantly more than the other clinical experiences. No statistical differences were found among the clinical experiences in other procedural errors. No statistically significant differences were found between age range and gender in additional root canals. Statistically significant differences were observed between the number of root canal retreatments in terms of age range and gender. Conclusions: Clinical experience affects the technical quality of root canal treatments. Fractured instruments and missed canals, especially by endodontic program students, should be given more attention.
