Influence of Method of Teaching Endodontics on the Self-Efficacy and Self-Perceived Competence of Undergraduate Dental Students

Exploring Undergraduate Students' Perspectives on Endodontic Treatment: A Cross-Sectional Study in Makkah

Background Students at two universities in Saudi Arabia found endodontics or root canal treatment (RCT) difficult due to challenges in the procedures. Until now, there has been no evidence that Umm Al-Qura University students face difficulties when performing RCT. Therefore, this study aims to explore students' perceptions of the critical steps in RCT. Methods A survey was conducted among 146 dental students at Umm Al-Qura University, Makkah, Saudi Arabia to assess their perceptions and challenges during RCT. Demographic information was collected in the first section, while the second section focused on identifying difficulties encountered during endodontic treatment stages. All participants provided signed electronic consent, and the study was approved by the university's institutional review board. Chi-squared tests were used to analyze the results. Results In a survey of 123 students, 94 (76.2%) found the endodontic specialty acceptable compared to other dental specialties (P < 0.001). Eighty-eight (71.5%) found RCT on the molars difficult (P < 0.001). Most students, 104 (84.6%), chose to have more clinical training to improve their clinical endodontic skills, and 77 (62.6%) chose to increase the number of instructors per student in the clinic (P < 0.05). Difficulties in performing RCT on premolars and during root canal obturation were statistically correlated with the academic year of the student (P < 0.05). Conclusion Dental students often struggle when performing RCT on molars. Some difficulties during RCT are correlated with the academic year of the student. Finally, from the students' perspective, improving endodontic skills involves providing better clinical training opportunities and increasing instructor-to-student ratios.

Students' performance in clinics and self-perceived Confidence in performing Endodontic procedures: A correlation study

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.

Effect of an endodontic e-learning application on students' performance during their first root canal treatment on real patients: a pilot study

BACKGROUND

E-learning has found its way into dental teaching in general and endodontic teaching in particular. The present study aimed to implement a newly developed multimedia learning application and assess its effect on students' first root canal treatment on real patients. With the COVID-19 outbreak, the application's performance was investigated during the pandemic.

METHODS

A total of 138 students in the initial clinical endodontic course participated in this study. The control group (n = 49) followed the traditional curriculum, including practice on artificial teeth and face-to-face teaching events. In addition to the traditional curriculum, test group 1 (n = 54) had access to an endodontic e-learning application containing videos demonstrating artificial teeth and patient cases. With the COVID-19 outbreak, test group 2 (n = 35) had no face-to-face teaching; however, endodontic patient treatments were included. The quality of students' first root canal treatment on real patients was compared using performance and radiographic assessment items. Statistical analysis was done using Kruskal-Wallis and chi-squared tests. Test groups received a questionnaire to assess the learning application. Test group 2 also completed a COVID-19-specific survey to measure students' perceptions of how the pandemic affected their endodontic education.

RESULTS

The results of endodontic treatments were significantly better for test group 1 (P < 0.001) and 2 (P < 0.001) than for the control group. Likewise, there were significantly fewer treatment errors in test group 1 (P < 0.001) and 2 (P < 0.001). No significant differences were found between test groups 1 and 2. Students of the test groups positively evaluated the e-learning application. Students of test group 2 expressed their fear of negative impacts on their course performance.

CONCLUSION

The e-learning application was well-received and seemed to improve endodontic education. The results imply that the quality of education may be maintained by implementing e-learning to compensate for face-to-face teaching. As no difference was found between online and face-to-face teaching, students' and lecturers' concerns that endodontic education is suffering because of the pandemic may be eased.

Pain and Avoidance during and after Endodontic Therapy: The Role of Pain Anticipation and Self-Efficacy

Background: Pain anticipation has been identified as a predictor of pain and avoidance with respect to endodontic therapy. Self-efficacy is also key to the development and maintenance of health behaviors and achieve patient adherence to treatment. However, the role of self-efficacy has not been studied yet in endodontic treatment. Methods: This study was conducted on 101 patients who needed root canal therapy. They had to fill a questionnaire before treatment registered pain anticipation and self-efficacy; during and after treatment were registered pain intensity and avoidance. Results: Pain anticipation explained pain during (Beta = 0.51, t = 5.82, p ≤ 0.001, [0.34, 0.69]) and after treatment (Beta = 0.38, t = 4.35, p ≤ 0.001, [0.21, 0.55]). Self-efficacy did not have an influence in pain values. Pain anticipation explained avoidance during (Beta = 0.51, t = 3.60, p ≤ 0.001, [0.23, 0.80]) and after treatment (Beta = 0.62, t = 4.29, p ≤ 0.001, [0.33, 0.91]). Self-efficacy had a significant role in avoidance during treatment (Beta = 0.12, t = 2.19, p ≤ 0.03, [0.01, 0.23]) with a strong moderation relationship between pain anticipation and avoidance when self-efficacy was medium (Beta = 0.44, t = 3.24, p = 0.002, [0.17, 0.72]) or high (Beta = 0.84, t = 3.5, p ≤ 0.001, [0.37, 1.33]). Self-efficacy was not significant respect to avoidance after treatment. Conclusions: Self-efficacy is an important variable in endodontic therapy due to their moderating effect between pain anticipation and avoidance behavior during the procedure. It is necessary to improve the results of root canal therapy and reduce patient’s avoidance in order to take into account this variable.

German Dentists' Preferences for the Treatment of Apical Periodontitis: A Cross-Sectional Survey

Currently, there is no standard treatment protocol for apical periodontitis (AP). Thus, restorable teeth might get extracted and replaced prosthetically. This study evaluated German dentists’ preferred AP treatment decisions and the influencing factors for selecting tooth retention by initial/repeated surgical/non-surgical root-canal treatment (RCT) or extraction with/without prosthetic replacement. Through an online-survey, participants (n = 260) rated different treatment options for four case scenarios with AP in anterior/posterior teeth without/with previous RCT. Statistical analysis included the Friedman test for intra-case comparisons and Chi-squared test for factor-associations (p ≤ 0.05). Tooth retention using initial/repeated RCT was ranked first in all scenarios and rated as (very) appropriate by most participants, while implant-supported crowns (ISC) and apicoectomy had the second ratings. ISC were preferred more on posterior teeth or previous root-canal-treated teeth. Rating levels of treatment options displayed significant differences for all case scenarios. Posterior tooth retention by RCT demonstrated a significant association with work experience. Tooth retention with previous RCT displayed a significant correlation with dentists’ privately insured patients. Most dentists preferred tooth preserving with initial/repeated RCT, while others selected non-evidence-based choices. This reflects a lack of consensus of AP treatment decisions in Germany. Fixed treatment guidelines and further evaluation of treatment–decision-correlated factors are recommended for correct treatment planning.
