The criteria typically used include the incidence of procedural mistakes and obturation characteristics, such as length and density. Apical periodontitis in root canal treated teeth (RCTT) is a significant public health problem. Apical periodontitis in root canal treated teeth (RCTT) is a significant public health problem. Epidemiological studies are conducted to explore the frequency of the Periapical status of RCTT in several populations. Many authors have examined the effect of RCT and coronal restoration qualities on the occurrence of apical periodontitis. While some researchers exhibited that periapical health relied on coronal restorations quality, others presented that it depended on the technical quality of RCT. On the other hand, some studies have proposed that success depends on both of them. This is a retrospective study done using the patients’ files and examination of post-operative radiographs (Periapicals). Convenient sampling was done and 333 patients’ files were selected from Muneseya clinics after seeking approval from the Research center and clinic director. Underfilling, overfilling and PA radiolucencies did not show any statistically significant differences based on dentistry levels. However, a statistically significant difference was observed when comparing the prevalence of voids (p-value: .002), which showed that the highest number of voids were seen among patients treated by level 9 students (50%).
It was found that the Overall quality of root canal fillings by undergraduate students is unsatisfactory.
