نبذة مختصرة : Introduction: Endodontic treatment errors (EEs) can lead to complications and require additional follow- up care. This study aimed to investigate the prevalence of root canal treatment errors among dental students, identifying error types based on radiographic criteria, tooth type, location, and technical errors. Materials & Methods: A cross-sectional study analyzed data from 201 patients who underwent root canal treatment at Ilam University of Medical Sciences between 2021 and 2022. Inclusion criteria were confirmed root disease diagnosis, adherence to standard treatment protocol, availability of radiographs, and complete patient files. The protocol included rubber dam isolation, radiographic length determination, manual file canal preparation, irrigation, obturation with the lateral compression method, and temporary restoration. Two endodontists evaluated filling length, density, convergence, and technical errors such as floor perforation, broken instruments, transportation, ledge formation, and access cavity gouging. Results: The study included 89 male (44.3%) and 112 female (55.7%) dental students with a mean age of 25.36 years. Among the 201 patients (28.9% male, 71.1% female; mean age 35.24 years), 71.6% had fillings of appropriate length, 12.14% short, and 15.9% long. Appropriate density was observed in 67.6%, and convergence in 86.1%. Technical errors included ledge formation (8.5%), floor perforation (1%), access cavity gouging (1.5%), and broken instruments (0.5%). A significant relationship was found between density and tooth type (p<0.002) and convergence and tooth type (p < 0.009). Conclusion: Proper filling, convergence, and density were more frequent in anterior teeth. Maxillary teeth had higher rates of proper filling compared to mandibular teeth. The overall rate of treatment errors was low, likely due to professor supervision. [ABSTRACT FROM AUTHOR]
