[PMID: 39036025 PMCID: PMC11260050 DOI: 10.11604/pamj.2024.47.166.39321] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Accepted: 01/18/2024] [Indexed: 07/23/2024] Open
Abstract
Introduction the three-dimensional fluid-tight obturation of the root canal system ends the endodontic treatment process and the technical quality of obturation of the root canal (RC) is a determinant of the outcome of the treatment. This final stage of RCT is critical in the outcome of treatment, thus the need to have adequate and quality obturation. The audit of the performance of students in this aspect evaluates performances and identifies where there is a need for improvement. Therefore, we set out to evaluate the quality of root canal obturation performed by undergraduate and postgraduate clinical dental students. Methods a cross-sectional study that evaluated the root canal obturation performed by undergraduate and postgraduate students in a teaching hospital, for 1 year. The radiographic evaluation was done by calibrated assessors. The radiographs were viewed under magnifying lenses (x3.5). The adequacy of length and homogeneity of the density of obturation were the outcome variables assessed in all the categories of teeth treated among patients who are 18 years and above, seen during the study period. Results eighty-four maxillary and 36 mandibular teeth were root-filled in 97 patients with a mean age of 37.6 years ± 14.7 SD. A good proportion (47.5%) of the root fillings were done by the postgraduate doctors. Most of the canals (69.4%) had acceptable lengths while density was acceptable in only 37.7%. Slightly over half of canals with acceptable length (64 out of 127; 50.4%) were reported in teeth with single canals (p=0.000) likewise with density (28;40.6%). Overall acceptable length and root filling density was 28.9% and there was no statistical significance in the performances of the operators in relation to the length of root filling (p=0.109), and density (p=0.55). Conclusion the overall acceptable length and root filling density was 28.9% among both undergraduate and postgraduate students. The adequacy of root canal filling may be dependent on experience, the complexity of the tooth, and the method of instrumentation.

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.

The Assessment of Quality of the Root Canal Filling and the Number of Visits Needed for Completing Primary Root Canal Treatment by Operators with Different Experience. Bioengineering (Basel) 2022; 9:bioengineering9090468. [PMID: 36135014 PMCID: PMC9495316 DOI: 10.3390/bioengineering9090468] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2022] [Revised: 08/12/2022] [Accepted: 09/10/2022] [Indexed: 11/17/2022] Open
Abstract
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.

Abstract
BACKGROUND This study was aimed to evaluate the application of WeChat-based flipped classroom in root canal filling teaching in a preclinical endodontic course. METHODS A two-group comparative study was designed. The pre-class test, on-site quiz, and root canal filling on extracted premolars were performed by students from a lecture-based classroom group (LG, n = 30) and a WeChat-based flipped classroom group (WFG, n = 30). Results of the Pre-class test and on-site quiz were analyzed by independent samples t-test. Post-filling radiographs were taken and evaluated by a specialist in oral radiology who was blinded to grouping. Results of root canal fillings were analyzed by the Pearson chi-square test. Student responses in questionnaires were analyzed by Fisher's exact test. RESULTS The students in WFG could get significantly higher scores in the on-site test and make better performances in root canal filling than those in LG. In terms of questionnaires, students from WFG were perceived to be more motivated to learn, better to understand the knowledge, better to improve communication and clinical skills, easier to perform root canal filling but spending more time. CONCLUSION The WeChat-based flipped classroom teaching can have a better effect than lecture-based teaching on root canal filling learning for students with limited endodontic experiences.

Abstract
OBJECTIVE The aim of this article is to evaluate the quality of filling in endodontically treated root canals using the lateral condensation technique and modified lateral condensation technique. MATERIALS AND METHODS Thirty-two single-rooted teeth were divided into two groups that were assigned by simple randomization according to the filling technique. Once the endodontic treatment was performed, a periapical radiograph was taken to assess the quality according to the radiographic density and tomography was taken to evaluate the quality according to the tomographic volume of spaces, compared with the post-preparation biomechanical tomography. Finally, we performed a statistical analysis (Student's t-test) to evaluate whether there were differences between the types of filling. RESULTS Radiographic radiodensity was 182.89 ± 9.81 and 186.72 ± 6.97 HU for teeth treated with the lateral condensation technique and modified lateral condensation technique, respectively. The void volume was 3.75 ± 2.35 and 2.43 ± 1.18 mm3 for teeth treated with the lateral condensation technique and modified lateral condensation technique, respectively. CONCLUSION No significant differences were found between the techniques for both filling quality parameters.
