Introduction. The aim is to objectively compare the root canal treatment quality in training performed using natural and artificial teeth by undergraduate preclinical students. Materials and methods. A total of 265 preclinical procedures performed on natural (134 cases) and artificial teeth (131 cases) over four consecutive projects was assessed. Radiographic evaluations were performed by two experienced endodontists to assess the technical quality of root obturation and the presence of iatrogenic errors. A P value ≤ 0.05 was deemed statistically significant. Results and discussion. Artificial teeth were correlated with a significantly higher number of acceptable cases and significantly fewer iatrogenic errors in comparison with natural teeth. Natural teeth were correlated with significantly more under-filled cases in comparison with artificial teeth with significantly more ledges, which was a significantly correlated cause of under-filling. Conclusions. Artificial teeth are suitable models for preclinical endodontic training, since they ensure predictable technical outcomes in comparison with natural teeth.
