“…The results of the present study indicated that separated instruments were found mostly in the MB1 canal of maxillary first molars. This finding is consistent with previous investigations [27][28][29][30][31][32]. A higher rate of separated instruments in first molars than in premolars can be explained by their more difficult access as well as the presence of greater anatomical complexities [29].…”

“…The present study showed that a range of procedural errors occurred that could readily be detected using CBCT imaging. The overall patterns reported through CBCT evaluation in the present study reinforce the findings of previous studies based on periapical radiographs, with underfilling being the most common procedural error, especially in the MB1 canal of maxillary first molars [10,12,[26][27][28][29][30][31][32][33]. Underfilling of root canals in maxillary molars can be explained by their more complex anatomy with narrow and curved root canals and an increased probability of ledge formation compared to maxillary premolars [29].…”

A range of procedural errors can occur when performing endodontic treatment on posterior teeth. These errors may decrease the success rate in endodontic practice. This study assessed the prevalence of procedural errors and the quality of endodontic treatments in maxillary molars and premolars using cone-beam computed tomography (CBCT). CBCT scans from two private radiology centers were assessed retrospectively to ensure the same calculated sample size of 327 teeth for each of the four maxillary posterior tooth types (a total of 1,308 endodontically treated teeth). Image sets were evaluated for procedural errors categorized as follows: obturation length (overfilling or underfilling by >2 mm short of the root apex), missed canals, perforations, strip perforations (with extrusion of material into the furcation area), separated instruments in the root canal space, and root fracture. Data were analyzed with SPSS version 20 (SPSS Inc., Chicago, IL, USA), and frequency data was assessed using the Monte Carlo test at the 0.05 level of significance. The procedural errors most commonly reported in the present study were from most frequent to least frequent: underfilled canals (50.0%), missed canals (27.5%), overfilled canals (12.5%), apical perforations (5.0%), separated instruments (3.1%), and root fractures (1.9%). No strip perforations (with extrusion of material into the furcation area) were seen in the study (0%). Underfilled and missed root canals were the most frequent procedural errors identified in the present study. These findings underline the importance of more consideration of critical working length management during all stages of root canal treatment, greater awareness of root canal anatomy, and the use of imaging and diagnostic devices that enhance the ability to identify and treat root canals both safely and effectively.

The aim of this study was to evaluate the technical quality of endodontic access cavities performed by M1 and M2 students during the clinical teaching of endodontics. The study population consisted of patients who came for consultation in the clinic of the Conservative Odontology-Endodontics Department of the Institute of Odontology and Stomatology of Dakar. The inclusion criteria were for teeth for which endodontic treatment was indicated and an access cavity was performed for the first time and exclusively by a student as part of the clinical training in endodontics. A survey form was drawn up containing the following headings: contour shape, visibility of canal entrances, body shape, and accidents along the way (stop, perforations, or flattening of the pulp floor). The chi-squared test was used to compare quantitative and qualitative variables and the significance level was set at p<0.05.A total of 139 endodontic access cavities were made by students (56.8% by Master 2 (M2) students and 43.2% by Master 1 (M1) students). Of these, 35% of the access cavities made by M1 students were acceptable versus 44% acceptable for M2. The difference was statistically significant (p<0.05).It appears from this study that the rate of technically acceptable access cavities made by the students of the Institute of Odonto-Stomatology of Dakar was insufficient. Thus, modifications must be made in the preclinical and clinical training program of Endodontics students.
