“…Tese rates were 23.3% and 15.3%, respectively, in a study by Mozayeni et al [38] in a dental school in Tehran, Iran, 21% and 9%, respectively, in a study by Lynch and Burke [39], and 37.3% and 7.8%, respectively, in a study by Ilgüy et al [5] on dental students in Turkey. Nouroloyouni et al [22] also reported that underflling was the most common error in the second and frst mandibular premolars (9.5% compared with 9.2%), respectively. In addition, overflling was the second most common error in this study (6.3%).…”

Objectives. This study assessed the quality of endodontic treatment and the prevalence of procedural errors in permanent mandibular molars using cone-beam computed tomography (CBCT). Materials and Methods. This cross-sectional study was conducted on 328 CBCT scans (182 females and 146 males) of endodontically treated mandibular molars retrieved from the archives of two radiology centers in Ardabil city, Iran, in 2019. Mandibular molars were evaluated on sagittal, coronal, and axial sections regarding obturation length, obturation density (voids), missed canals, broken instruments, apical perforation, strip perforation, ledge formation, transportation, root fracture, root resorption, and periapical lesions by a senior dental student under the supervision of an oral and maxillofacial radiologist and an endodontist. Differences between the frequency of procedural errors and tooth type and gender were analyzed by the chi-square test. Results. The frequency of underfilling, missed canals, overfilling, voids, apical perforation, transportation, ledge formation, broken instruments, root fracture, strip perforation, root resorption, and periapical lesions was 34.8%, 17.4%, 16.8%, 14.3%, 7.3%, 6.1%, 4.3%, 3%, 1.2%, 0.6%, 5.5%, and 46%, respectively. The frequency of root fracture was significantly higher in females than in males P < 0.05 . The prevalence of underfilling was the highest in right second molars (47.2%), followed by right first molars, left second molars, and left first molars P < 0.005 . The frequency of transportation was maximum in right first molars (10%), followed by right second molars, left first molars, and left second molars P < 0.04 . Conclusion. Underfilling, missed canals, and overfilling were the most prevalent procedural errors in mandibular molars in our study population.

“…Te CBCT is also a highly advantageous educational instrument. With the aid of CBCT, the quality of endodontic treatments and iatrogenic errors can be determined utilizing existing archives that reveal the weak points of clinicians, allowing for target-based learning to reduce these weaknesses [22].…”

“…The quality of RCT and incidence of procedural errors can vary between general dentists and endodontists and also among different regions, as documented in several studies [4][5][6][7][8]. Procedural errors can include missed canals (detecting an unfilled root canal by changing the radiographic angle), over-or underfilled canals (overfilling beyond the tooth apex, underfilling by >2 mm short of the root apex), and root perforations (communication between the root canal system and periodontium), as well as instrument separation (presence of a broken piece of instrument in the root canal space or in the periapical area) [9].…”

“…Procedural errors can include missed canals (detecting an unfilled root canal by changing the radiographic angle), over- or underfilled canals (overfilling beyond the tooth apex, underfilling by >2 mm short of the root apex), and root perforations (communication between the root canal system and periodontium), as well as instrument separation (presence of a broken piece of instrument in the root canal space or in the periapical area) [ 9 ]. Previous studies have reported that the most frequent procedural errors were ledges [ 10 ], underfilled canals [ 6 , 11 ], and inadequate radiopacity of the root filling [ 12 ].…”

“…Special care should be taken when working on maxillary posterior teeth, which had a significantly higher error rate when compared to anterior teeth [ 1 ]. Some studies have examined the prevalence of iatrogenic errors involving mandibular premolars and molars in our studied population [ 6 , 22 ]. However, there is also a high frequency of errors in maxillary first molars and other posterior teeth, yet information about them is very limited and has mostly involved root canals performed by dental students and two-dimensional radiographs [ 5 , 7 , 8 , 11 ].…”

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.
