... Information related to endodontic treatment, coronary restorations, periapical conditions, and root integrity was collected. The appropriate apical limit of filling was established as one at which the filling-apex distance was between 0 and 2 mm, and inadequate in case of subfillings greater than 2 mm (Sjögren et al., 1990;Farzaneh et al., 2004;Heling et al., 2001;İlgüy et al., 2013;Lee et al., 2012;Liang, Li, Wesselink, Wu 2011;Peak et al., 2001;Ridell et al., 2006;Smith, Setchell, Harty, 1993;Tani-Ishii, Teranaka, 2003), overfillings or untreated root canals. In the case of the lateral limit of filling, it was considered inadequate when it was greater or much lower than the proportion of one third of the width of the root evaluated, or even in the case of untreated root canals. ...
Cone Beam Computed Tomography has become an important part of endodontic practice as it allows the visualization and manipulation of three-dimensional images. The present study aimed to evaluate the periapical condition of endodontically treated teeth through the analysis of computed tomography scans. This is a retrospective cross-sectional study in which 707 teeth were analyzed. The different dental groups, the presence of an intraradicular retainer, coronary restoration, root fracture, and root resorption, as well as the apical and lateral limits of the filling and the quality of the filling, were evaluated. The data were tabulated and then statistically treated through descriptive analyses and associations. The Kolmogorov-Smirnov and chi-square tests were used, and the significance level was 95% (p≤0.05). Of the total number of teeth analyzed, the maxillary incisors were the most prevalent (27.7%), followed by the maxillary premolars (18.8%) and the mandibular molars (15.1%). Significant associations were observed between the presence of alterations in the periapex and the apical limit (p=0.001), the lateral limit of the filling (p=0.000), the quality of the filling (p=0.030) and the presence of root resorption (0.000). It is concluded that unsatisfactory filling of root canals is a relevant factor for the presence of periapical diseases.
... Therefore, it is imperative to make every effort to minimize such incidents. The assessment of endodontic treatments conducted by dental students has been a central theme in numerous studies, exploring various facets and dimensions including treatment outcome, 9 quality of treatment, 10 factors associated with treatment quality, 11 students' perception of difficulties, 12 and their confidence level to treat difficult cases. 13 To the best of our knowledge, there are only two studies 14,15 that have evaluated the endodontic performance of dental students in the United Arab Emirates (UAE). ...
Aims and background: To assess the procedural errors committed by undergraduate students at RAK College of Dental Sciences, during root canal treatments and the factors associated with these errors. Materials and methods: In this cross-sectional study, 180 self-administered questionnaires were distributed, each comprising 26 questions, among 4th and 5th-year students. Participants were requested to report their endodontic mishaps based on feedback from their supervisors. The questionnaire assessed the frequency and types of procedural errors, considering patient, operator, and tooth-related factors. Data were collected tabulated and analyzed using the Chi-square test. Results: A total of 124 root canal-treated teeth exhibiting iatrogenic errors done by students were assessed. Out of which, 53% were performed by 5th-year students, and 69% were conducted by female operators. About 62% of errors occurred in the upper teeth and 68% in the posterior teeth. The most prevalent errors during the rubber dam isolation step were soft tissue trauma (21%) and isolation leakage (20%), significantly associated with limited mouth opening, excessive salivation, and tooth malalignment (p < 0.05). Apical blockage (15%) emerged as the most frequent error during instrumentation phase, showing a significant association with canal dimension and curvature (p < 0.05). For access cavity and obturation phases, under-extended cavity (9%), and under-extended filling (11%) were the most reported errors, respectively. Conclusion: Tooth isolation emerges as a particularly challenging aspect for dental students, particularly when dealing with patients exhibiting limited mouth opening and excessive salivation. Clinical significance: Clinical instructors should caution the undergraduates about the heightened risk of endodontic procedural errors when dealing with patients exhibiting limited mouth opening, excessive salivation, tooth misalignment, and narrow canals. Addressing these challenges is crucial for enhancing the proficiency of undergraduate students in performing successful root canal treatments.
... These factors contribute to elevated stress levels and can result in a loss of confidence among students during root canal treatment, leading to suboptimal outcomes [2]. A key factor in determining students' abilities is the quality of their endodontic treatment, which is frequently evaluated as part of the assessment of their competency [3]. Recent assessments have shown a considerable percentage of students performing subpar endodontic operations, which raises questions about the effectiveness and caliber of their clinical training [4,5]. ...
Background
This study aimed to determine the confidence of senior dental students in Qassim University’s undergraduate dentistry program in Saudi Arabia regarding their capacity to perform endodontic procedures. The study’s objective was to pinpoint areas of weakness and offer suggestions for potential improvement of endodontic and clinical training for dental students.
Methodology
Using anonymous survey forms, 120 senior dental students were surveyed. Students’ self-reported levels of confidence in performing various endodontic procedures, such as periapical radiographs, rubber dam placement, endodontically treated tooth restoration, anesthesia, broken instrument removal, and endodontic retreatment, were studied in this survey. A Likert-style rating scale of 1 to 5 was used in the survey, with 1 denoting high confidence and 5 denoting low confidence.
Results
The majority of senior dental students at Qassim University reported high levels of confidence in taking periapical radiographs, with 64.04% indicating a high level of confidence. The second most assured field was rubber dam installation, with 47.6% of students expressing high levels of assurance. Confidence levels were noticeably lower during more difficult procedures such as endodontic retreatment and the removal of broken instruments. While 12% of students expressed high confidence in endodontic retreatment, only 3.46% of students expressed high confidence in removing broken instruments. According to Pearson’s correlation (r = 0.352, p = 0.001), there was a significant and favorable correlation between competency level and confidence in performing various endodontic procedure-related steps.
Conclusions
The study’s findings suggest that senior dentistry students at Qassim University might benefit from additional training and assistance in some endodontic treatment areas. The lack of confidence displayed during more challenging procedures, such as the removal of broken instruments and endodontic retreatment, demonstrates the need for additional training and supervision in such cases. The results of this study may be useful for educators in other dental colleges who wish to consider developing new teaching techniques, utilizing simulators and digital learning tools, and increasing opportunities for hands-on training and supervision to improve dental students’ self-confidence and skills.
... A CBCT study in the German population reported an extruded sealer in 8.1% of endodontically treated teeth [36]. Extrusion of all kinds of root-filling material was observed between 1.09% and 31.8% in previous studies [9, [36][37][38][39][40][41]. Although it is difficult to distinguish gutta-percha from root canal sealer radiographically, studies examining sealer extrusion reported a prevalence of 6.9-8.12% ...
... Although these studies used periapical radiography, their results were close to the current study (12.61%). Similarly, in some studies where all maxillary and mandibular premolars were evaluated together, extrusion was reported between 4.59% and 23% [38,40,41,43,45]. The fact that these studies did not distinguish between root and canal counts when obtaining information can be used to explain the large variation in percentage. ...
... Çulha E, Tunç F xx using CBCT images. In previous studies that have experienced this challenge, "overfilled", "overextended", "over apex", "long filling", and "inadequate obturation" have been used to describe extruding root canal filling material, regardless of gutta-percha or root canal sealers [9, [36][37][38][39][40][41]. There was only one study that specifically used the term "sealer puff" for the extrusion of root canal sealers [36]. ...
Objective: Overfilling a root canal has a negative influence on the prognosis of teeth with apical periodontitis. This study proposed to assess extruded sealer and gutta-percha in single-rooted teeth within a Turkish subpopulation using cone-beam computed tomography. Methods: The study included cone-beam computed tomography scans of 2,346 endodontically treated teeth with a single root and foramen from a private dental clinic's archive. Teeth were divided into four groups: maxillary anteriors, mandibular anteriors, mandibular premolars, and maxillary second premolars. Two endodontists analyzed the scans at all planes and recorded information pertaining to tooth number, tooth type, and presence of extrusion. To examine the data, a chi-square test with a 0.05 p-value was performed. Results: Extrusion was detected in 256 (10.91%) of the single-rooted teeth. There was significant difference among the groups (p<0.05). Extrusion was significantly higher in the maxillary anteriors than in the other tooth groups. Maxillary second premolars had lower extrusion compared to the other tooth groups. There was no statistical relationship between the maxillary anterior tooth groups and the presence of extrusion (p=0.338). Conclusion: Maxillary anteriors had higher root canal filling material extrusion than the other tooth groups, while maxillary second premolars had lower extrusion.
... Similar to previous studies, a periapical X-ray examination was performed to evaluate the quality of root canal fillings. [28][29][30] The data indicated that the root canal fillings in the face-to-face training group ended at an ideal apical distance and were significantly more homogeneous than those in the online group. The degree of taper that the two groups examined was also similar. ...
Purpose:
The aim of this study was to evaluate the competency of undergraduate students in following the principles of access cavity preparation and the radiographic quality of root canal filling in maxillary molar teeth in either online or face-to-face education courses during the novel coronavirus disease 2019 (COVID-19) pandemic.
Methods:
A total of 178 extracted maxillary molar teeth that underwent endodontic dental treatment by undergraduate students who completed the endodontic preclinical practice course online or face-to-face during the COVID-19 pandemic were retrospectively analyzed. A visual access cavity examination determined the form, width of the cavity, deroofing of the pulp chamber, and the presence of a perforation. Root canal fillings were examined radiographically on periapical radiographs for length, homogeneity, taper, and the presence of iatrogenic defects. Statistical analysis was performed using the chi-square test.
Results:
The incidence of incorrect form, wide cavities, and perforation was statistically higher in the online group than in the face-to-face group (p < 0.05). It was determined that root filling length and homogeneity were more successful in the face-to-face group (p < 0.05). When evaluated for iatrogenic errors, the presence of broken instruments was found to be significantly higher in the online group (p < 0.05). There was no significant difference between the groups in other iatrogenic errors and the taper of the root canal filling (p > 0.05).
Conclusion:
The students who underwent face-to-face education were more successful in accessing cavity preparation and root canal fillings than the students who undertook online education.
... Te success rate of endodontic treatments performed by general dentists is reportedly 60% to 75% [4]. Procedural errors are among the main factors responsible for the suboptimal success rate of endodontic treatments performed by general dentists [5,6].

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.
... [18] Conflicting results were also reported by other studies [19,20] and these variations were due to differences in the clinical teaching practices as well as different criteria used for the radiographic assessment. [21] The apical length parameters in this study were fairly achieved with 92.1% of the canals filled to the acceptable length, in within 0-2 mm from the apex. The combination of radiograph and apex locator as used in this study ensures that the root canal is adequately cleaned and filled to the acceptable working length. ...
... The RCT that was performed to a high technical standard as having both adequate length [40] and homogeneity, will ensure the healing of the periapical pathosis and produce a predictable long-term success. [21,41,42] This is confirmed by the results of the present study. About 92% of the acceptable obturation quality evaluated from this study was presented with a healthy periapical (P < 0.005). ...
Introduction: Root canal treatment (RCT) and its coronal restoration should be regularly assessed to ensure a successful treatment outcome. The aim of the current study is to evaluate the relationship between the obturation technical quality and coronal restoration in the clinical and radiographic outcome of RCT provided by Malaysian undergraduate students. Materials and Methods: A total of 143 root-treated teeth from 136 patients were evaluated through clinical examinations and periapical radiographs with a mean follow-up period of 2.4 (standard deviation = 1.59) years. The quality of the coronal restoration was classified according to modified United States Public Health Service criteria and the technical quality of the obturation was assessed based on two variables: length and density. Periapical status was evaluated according to periapical index scores. Results: About 64% of the teeth were classified as healthy with a significant reduction of apical periodontitis from 70.3% preoperatively to 36% at reassessment (P < 0.001). About 92.1% of obturation was of acceptable length, whereas 5% underfilled and 2.9% overfilled. Teeth with acceptable obturation length were five times less likely associated with apical periodontitis than the inadequately filled ones. 90% of canals had adequate obturation density with no significant association to apical periodontitis. Teeth restored with intracoronal restorations had 50% more chance of developing apical periodontitis. Inadequately restored teeth and teeth with poor obturation quality were associated with three times more likely apical periodontitis occurrence. The quality of endodontic treatment and the coronal restoration significantly influenced the periapical status (P < 0.001). Conclusion: The radiographic obturation quality and coronal restorations of the RCTs performed by the undergraduate students in a Malaysian public dental school were acceptable in 63.8% of cases with a 64% favorable outcome.

... In prior studies (8,17,18), it was noted that molar teeth were the most commonly treated with RCT, a finding that aligns with the results of this study, where the molars with RCT and PL constituted 58% of the total cases. In addition, this study, which included participants from various countries, discovered no appreciable differences between the groups of teeth with RCT and PL. ...
... 9 The quality of the endodontic treatment is a significant parameter for evaluating students' proficiency. 10 Recent researches that assessed the outcome, and quality of endodontic procedures have highlighted a high percentage of under par endodontic treatments carried out by students. 11,12 This is a matter of concern as the quality of clinical training of students in any subject is reflected in their competency and self-confidence. ...
Objective:
The study aimed to evaluate undergraduate dental students' self-perceived confidence in carrying out Endodontic procedures and correlating it with their performance in Endodontic clinics.
Methods:
The correlational study was conducted on fifth year dental students at Qassim University, Saudi Arabia. The self-perceived confidence of students was assessed by using Endodontic Self-Perceived Confidence Scale (ESCS). The students' endodontic clinical performance scores were obtained from the department head. Data were analyzed by IBM SPSS-23.0. Descriptive statistics were recorded as percentages, frequencies, and mean. Chi-square test was used for gender-wise comparison of all items of ESCS, Student t-test was used for comparing means and Pearson correlation coefficient was utilized for exploring correlation.
Results:
Over all response rate was 91.8%. Students exhibited the highest confidence level for achieving rubber dam isolation (4.57±0.66) while the lowest confidence level was documented for the treatment of teeth with immature apices (2.82±0.95). The mean self-confidence score of male students on ESCS was higher than the female students (P-value=0.18). However, mean endodontic clinic score of female students was significantly higher than the male students (P-value=0.02). The insignificant correlation was noted between the students' mean confidence scores and endodontic clinical performance scores (P-value=0.82).
Conclusions:
The insignificant correlation between self-perceived confidence and clinic scores raises significant caveats for utilizing the self-assessment in the aforementioned group. Hence, the students should be adequately trained in self-assessment to prepare them for lifetime learning. Additionally, clinical instructors by creating a supportive learning environment should help students to deal with their shortcomings.
... In this investigation, not only the extrusion of gutta-percha cones but also any amount of sealer beyond apex was considered as overfilling. Various studies have investigated the radiographic quality of root canal fillings performed by clinical dental students [17,[37][38][39][40][41]. In this research, the adequate length and density of RCT performed by 4thyear students were found in 81.71% and 92.86%, respectively. ...
... A very similar distribution was presented by other scientists [24,36,81]. According to other studies, two-thirds of treated teeth by 4th and 5th year students were premolars and molars [23,37], while one study presented a uniform distribution of teeth treated by students [38]. According to the ESE undergraduate curriculum guidelines for endodontology [10], students should gain adequate experience in the treatment of anterior, premolar, and uncomplicated molar teeth. ...
The main goal of root canal treatment (RCT) is to eradicate or essentially diminish the microbial population within the root canal system and to prevent reinfection by a proper chemo-mechanical preparation and hermetic final obturation of the root canal space. The aim of this study was to assess the quality of the root canal filling and the number of visits needed for completing RCT by operators with different experience, including dentistry students (4th and 5th year), general dental practitioners (GDPs), and endodontists. Data from medical records of 798 patients were analyzed , obtaining 900 teeth and 1773 obturated canals according to the inclusion and exclusion criteria. A similar number of teeth was assessed in each group in terms of density and length of root canal filling and number of visits. The larger number of visits and the lower quality of treatment was observed for 4th year students than for other groups (p < 0.05); in contrast, the endodontists needed the lowest number of visits to complete RCT and more often overfilled teeth than other operator groups (p < 0.05). Interestingly, no statistical difference in quality of root canal filling was noted between 5th year students, GPDs and endodontists. The treatment of lower teeth demanded statistically more visits than that of upper teeth (p < 0.05). The results of the study emphasize that most of the root canal filling performed by operators was considered adequate, regardless of tooth type, files used and number of visits.
