Purpose/objectives Self-assessment is an essential skill for dental professionals. Understanding global trends in self-assessment can highlight the learning needs of students across a diversity of cultural backgrounds. The aim of this study is to compare the self-assessment ability of dental students in the United States and Japan, where cultural backgrounds may differ. Methods Students in the United States (n = 176) completed a typodont premolar and anterior Class II and Class III preparation and restoration. Students in Japan (n = 175) completed a typodont premolar crown preparation. Students and faculty then evaluated the student performance using rubrics for each respective procedure. The difference between the student's self-assessment score and the average faculty score (S-F gap) was calculated and the data were analyzed. Results The mean S-F gap was 2.8% in Japan and 7.6% in the United States. This indicates that Japanese students tended to assess themselves closer to their faculty graders than students in the United States. On average, students in both countries scored themselves higher than their faculty graders. Students in the United States more frequently overestimated their performance and students in Japan more frequently underestimated their performance. For students in the lower quartile, the mean S-F gap was 5.1% in Japan and 14.6% in the United States, indicating a large cultural discrepancy in the lower quartile groups. Conclusions Although different preclinical procedures were compared, our findings demonstrated that Japanese students may score themselves more closely to their faculty assessors than students in the United States. Further investigation with more students completing the same preclinical activity will be needed.

Introduction During the COVID‐19 pandemic, dental schools were required to reformat their curricula to accommodate regulations mandated to protect the health of students and faculty. For students enrolled in the Operative Dentistry preclinical courses at the Harvard School of Dental Medicine (HSDM), this modified curriculum included frontloading the course with lectures delivered remotely, followed by in‐person laboratory exercises of learned concepts. The aim of this article was to determine the impact that the modifications had on student performance and student self‐evaluation capabilities. Materials and methods Thirty‐eight students were introduced to this restructured course. Their performance in a final multiple‐choice (MC) examination, four preclinical laboratory competency assessments (class II amalgam preparation and restoration, class III composite preparation and restoration) and their self‐assessment of these preclinical competency assessments were then compared with the pre‐COVID pandemic (P‐CP) classes from years 2014 to 2019 (n = 216 students). Linear regressions were performed to determine differences in mean faculty scores, self‐assessment scores, student‐faculty score gaps (S‐F gaps) and absolute S‐F gaps seen between the class impacted by the pandemic and the P‐CP classes. Results The results demonstrated that students during the COVID‐19 pandemic (D‐CP) had a higher average faculty score in all four preclinical laboratory competency assessments and in the final MC examination. In addition, the S‐F gap was smaller in this cohort as compared with the P‐CP classes. Conclusion Despite the challenges of restructuring the preclinical curricula, D‐CP students performed better than their P‐CP predecessors in multiple facets of this Operative Dentistry course including self‐assessment accuracy.

PURPOSE/OBJECTIVE Self-assessment is a fundamental skill for dentists and other health care providers. It enables these professionals' ability to critically evaluate the quality of their clinical work and improve through self-directed learning. Researchers have investigated how gender affects self-assessment skills and have shown that male students tend to overestimate their performance while female students tend to underestimate theirs as compared to peer or faculty assessment. The goal of this study was to evaluate how the self-assessment skills of dental students differ by gender in operative preclinical dentistry. METHODS Third-year dental students (N = 208, Class of 2016-2021) self-assessed their work using the same rubrics as faculty on four operative dentistry competency examination procedures: Class II amalgam preparation and restoration and Class III resin-composite preparation and restoration. Two calibrated full-time faculty graded all procedures independently. The Student self-assessment-Faculty grade (S-F) gap scores were calculated and statistically analyzed. RESULTS Overall, both genders overestimated their self-assessment for all four procedures as compared to actual scores given by faculty. Males overestimated more significantly than females for Class II Amalgam preparation, but not for the other three procedures. However, when the S-F gap for all procedures was combined and analyzed together, male students significantly overestimated their self-assessments compared to female students. When female and male students grading scores were stratified into quartiles, there were significantly larger differences between males and females in the lower quartiles, which suggest that difference in self-assessment abilities was more prominent among the lower performing students. CONCLUSION The results of this study demonstrate that gender may affect the accuracy of self-assessment in operative preclinical dentistry.

Introduction A theory-practice gap in pre-doctoral dental education is a common source of stress for dental students. An interactive, small-group, case-based activity was designed to bridge the gap between pre-clinical and clinical experiences. The aim of our study was to assess the effectiveness of the case-based activity by evaluating students' comfort level in operative procedures. Materials and methods Over 5 years, a total of 172 second-year students from the classes of 2017 through 2021 participated in the case-based activity delivered after the completion of the core operative dentistry course. The exercise included a pre-activity online quiz, an in-class case-based session and a laboratory exercise. Students' self-reported comfort levels in performing operative procedures were collected by surveys at three different times. They included the post-course survey distributed after the completion of the core operative dentistry course, the post-activity survey distributed after the completion of the case-based activity, and the follow-up survey distributed after students completed their first operative procedures in clinic. Results There was a 93% response rate. The average rating of all eight statements revealed statistically significant increase in students' comfort level after completing the case-based activity and after performing their first operative procedures in the teaching practice. Conclusion This observation suggests that the case-based activity was effective in raising students' comfort levels. The activity may serve as an important tool in bridging the theory-practice gap between pre-clinical and clinical operative experiences.
