Assessment of the quality of root canal fillings performed on extracted teeth by undergraduate dental students in a sample from Saudi Arabia. BMC MEDICAL EDUCATION 2024; 24:157. [PMID: 38374029 PMCID: PMC10875893 DOI: 10.1186/s12909-024-05136-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Accepted: 02/05/2024] [Indexed: 02/21/2024]
Abstract
BACKGROUND The educational process in the field of endodontics commences with preclinical exercises to enhance students' proficiency in cleaning, shaping, and performing root canal fillings. Therefore, this study aimed to radiographically evaluate the technical quality of root canal fillings performed by preclinical students on extracted teeth at the College of Dentistry, University of Ha'il, Saudi Arabia. METHODS A total of 788 extracted human teeth received root canal treatment by undergraduate students. The samples were then gathered and radiographically assessed using the three quality criteria of length, density, and taper. The category of root canal fillings was classified as either acceptable or unacceptable. The criteria for evaluating the acceptability of filling quality were defined based on the presence of adequate length, density, and taper. The effectiveness of root canal fillings was also evaluated in relation to the tooth type, sex, and treatment year. The agreement between the examiners was evaluated using Cohen's kappa test, and the relationship between the research variables was determined using the chi-squared test. The significance threshold was set at 0. 05. RESULTS The overall quality of root filling was determined to be satisfactory in 532 (67.5%) of 788 endodontically treated extracted teeth. The majority of the research sample (88.1%) had enough length, 89.6% had adequate density, and 86.4% had acceptable taper. The quality of anterior teeth was substantially better than that of posterior teeth (p < 0.001). Our findings showed that the quality of root canals was better in 2022 than it had been in earlier years (p = 0.001). The three RCT quality criteria differed significantly when compared between sexes (p = 0.002). CONCLUSIONS The quality of the root canal fillings completed by undergraduate students was rated as acceptable. The findings of the research suggest that the implementation of routine assessments to evaluate the technical competence of undergraduate dental students performing root canal treatments could provide significant insights into the efficacy of the curriculum requirements.

Cone-Beam Computed Tomography Assessment of Prevalence of Procedural Errors in Maxillary Posterior Teeth. BIOMED RESEARCH INTERNATIONAL 2023; 2023:4439890. [PMID: 38116330 PMCID: PMC10730252 DOI: 10.1155/2023/4439890] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Revised: 11/06/2023] [Accepted: 11/29/2023] [Indexed: 12/21/2023]
Abstract
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.

Endodontic mishaps during root canal treatment performed by undergraduate dental students: An observational study. Medicine (Baltimore) 2021; 100:e27757. [PMID: 34964733 PMCID: PMC8615340 DOI: 10.1097/md.0000000000027757] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/05/2021] [Accepted: 10/27/2021] [Indexed: 01/05/2023] Open
Abstract
Endodontic mishaps during root canal treatment (RCT) are considered to be one of the most commonly encountered errors, which affect the quality of treatment and may have dangerous health implications for patients.The present study was conducted to assess the frequency and types of endodontic mishaps in root canal-treated teeth performed by undergraduate dental students.A total 404 endodontically treated teeth were performed by undergraduate dental students of King Khalid University College of Dentistry, Abha, Kingdom of Saudi Arabia. The radiographs of the endodontically treated teeth were studied for a period of 6 months, and the related demographic data were collected from patient files.The most commonly identified mishaps were related to obturation, where the maximum number of cases (68.1%) had under-obturated root canals. More endodontic mishaps were performed by students in level 9 education. The upper left 2nd molar teeth had a higher frequency of mishaps, and molars were found to have more access-related mishaps. Lastly, access-related and instrument-related mishaps had a low frequency of occurrence.The majority of endodontic mishaps found in the study sample were related to root canal obturation. The undergraduate students at level 9 were less proficient in conducting RCTs with many endodontic mishaps when compared to the cases performed by students at higher levels. The study suggests relevant guidance for dental students while performing RCTs, especially during obturation of the root canals.

Abstract
BACKGROUND Dental students are future dentists. Continuous assessment and improving of the educational curricula will ensure excellent academic performance of dental students and thus providing the community with the best treatment modalities. The aim of this study was to evaluate the root canal filling quality performed in extracted teeth by preclinical undergraduate Yemeni dental students. METHODS Root canal treatment was performed by undergraduate preclinical dental students on 331 extracted human teeth including 741 roots. The teeth were then collected and evaluated radiographically based on three criteria of quality (length, density, and taper). Cohen's Kappa test was used to assess the agreement between the examiners and Chi-squared test was used for the association between the study variables. The level of significant was set at α < 0.05. RESULTS The results of the study revealed that the overall quality of roots canals fillings was poor. However, more than half of the study sample (53.4%) had adequate length, 13.1% had adequate density, and 14.2% had adequate taper. Anterior as well as single-rooted teeth had significantly better quality than posterior and multi-rooted teeth, respectively. The root canal fillings quality mandibular teeth was better than of maxillary teeth with no significant difference (P > 0.05). CONCLUSION The findings of the study emphasize the need of improving the endodontic course in the preclinical level and more advanced techniques and instruments should be incorporated.
