Objectives: The interruption to clinical professions' instruction due to closures from the coronavirus disease 2019 pandemic posed a significant hurdle to clinical education and presented a necessity to shift how instruction was delivered to resume educational activities. This study sought to answer the research question: did the transition from in-person to virtual instruction for interprofessional education (IPE) have an impact on students' perceptions of team attitudes and skills to learn and work in interprofessional groups?

Methods: All participating first-year dental and second-year dental hygiene students enrolled in the campus-wide IPE course were invited to complete the Team Skills Scale (TSS) assessment before and after the course for two academic years 2019-2020 and 2020-2021. Paired t-tests were utilized to assess the change in student attitudes and skills from pre- to post-course assessment, and t-tests were used to assess mean differences between student cohorts 2019-2020 and 2020-2021.

Results: Within the student cohort 2019-2020 students reported significant improvement in all TSS items. Within the student cohort, 2020-2021 students reported significant improvement in all but three TSS items. There were only significant differences in mean values for student reported improvement in attitudes and skills for two TSS items between the 2019-2020 and 2020-2021 cohorts.

Conclusions: Dental and dental hygiene students report significant improvement in team attitudes and skills after participation in a campus-wide IPE course. The mode of administration of the course, in-person or virtual, did not have a significant impact on student-reported improvements.

Objectives: This study aimed to evaluate the impact of curriculum modifications on periodontal instrumentation skills development among classes of 2021, 2022, and 2023 during the COVID-19 pandemic.

Methods: The pandemic began and affected the three classes at different stages of their studies. Onsite simulation-based learning (SBL) was employed for the classes of 2021 and 2022; remote SBL was adopted for the class of 2023. Modified clinical education, due to social distancing guidelines, impacted the class of 2021 significantly and the class of 2022 to a lesser extent. A multiple linear regression model was built to examine the association between the fourth-year patient-based scaling competency examination scores and selected predictors.

Results: The classes of 2021 and 2023 showed consistent performances over time, while the class of 2022 exhibited significant variation exhibiting the lowest performance at the second-year practical examination. While the clinical experience of the class of 2021 was significantly less than that of the classes of 2022 and 2023, the fourth-year competency examination scores did not differ across the three classes. The clinic points (p = 0.014) significantly affected the fourth-year competency examination score while student gender (p = 0.18), the first-year (p = 0.736), and second-year (p = 0.198) practical examination scores showed no correlations.

Conclusion: Based on student performance in the fourth-year scaling competency examination, the curriculum modifications due to the COVID pandemic did not affect student learning outcomes. Clinical experience was the most influential determinant of skill development in periodontal instrumentation.

Objective: To test the association between socioeconomic and sociodemographic status of Brazilian dental students with discriminatory experiences suffered by them.

Methods: This multicenter cross-sectional study was conducted with 531 undergraduate dental students from four different Brazilian states. The Explicit Discrimination Scale (EDS) was used to measure the experience of discrimination in several daily situations. A questionnaire about sociodemographic and socioeconomic characteristics, form of admission, and permanence in dental schools was developed and validated by experts and six dental students through cognitive interviews. The EDS and questionnaire were sent to students by an online platform using snowball sampling. Descriptive analysis, bivariate tests, and multiple Poisson regression were performed.

Results: Among the participants, most were female, white, heterosexual, and cisgender. The mean EDS total score was higher among those students who used Brazilian Affirmative Actions for higher education access and permanence (p < 0.005). The multiple analysis indicated that students who were black (prevalence ratio [PR] = 1.484; 95% confidence interval [95%CI]: 1.291-1.705), women (PR = 1.227; 95%CI: 1.030-1.462), had lower monthly income (PR = 1.212; 95%CI: 1.043-1.409) and were lesbian, gay, bisexual, transgender, intersex, queer, pansexual, and plus (LGBTQIAP+) (PR = 1.466; 95%CI: 1.238-1.735) showed a higher probability of discriminatory experiences when compared to white, male and heterosexual students with higher monthly income.

Conclusion: There is a racial and social class pattern among dental students. The exclusionary factors such as black race, female gender, lower monthly income and being LGBTQIAP+ make students more vulnerable to discriminatory experiences.

Objectives: The purpose of this study was to compare student learning of cone beam computed tomography (CBCT) interpretation using immersive virtual reality (VR) and three-dimensional multiplanar (MP) reconstructions.

Methods: Sixty first-year dental students were randomly allocated to two groups, VR and MP, and underwent a one-on-one educational intervention to identify anatomic structures using CBCT data. All participants completed three multiple-choice questionnaires (MCQs) before (T1), immediately after (T2), and 2 weeks following (T3) the intervention. Additionally, pre-survey, post-survey, NASA Task Load Index (NASA-TLX), and presence questionnaires were completed. Analysis of objective measures of performance on MCQs and subjective data from the questionnaires was completed (α = 0.05).

Results: There was a significant increase in test performance and informational recall between T1-T2 and T1-T3 for VR and MP groups (p < 0.001). However, there were no significant differences in performance on MCQs between T2 and T3. Analysis of the Presence questionnaire indicated that the VR group felt decreased distraction (p = 0.013), increased realism (p = 0.035), and increased involvement (p = 0.047) during the educational intervention when compared with the MP group. Analysis of the NASA-TLX indicated that the VR group experienced more physical demand (p < 0.01) but similar cognitive demand when compared with the MP group. Qualitative responses indicated that the VR group had a more dynamic sense of visualization and manipulation compared to the MP group.

Conclusion: Results from this study show that VR is as effective as traditional MP methods of CBCT interpretation learning. Further benefits of VR educational intervention include increased involvement, realism and less distraction.

Purpose/objectives: The aim of this study was to quantitatively investigate the impact of stereoscopic three-dimensional (3D) vision on students' performance when compared with that of two-dimensional (2D) vision in a 3D virtual reality (VR) simulator.

Methods: Twenty-four dental students (second- and fourth-year BDS) were assigned to perform three operative tasks under 3D and 2D viewing conditions on a Virteasy (HRV) simulator. Groups were crossed over and all students performed the same tasks under the alternate viewing conditions. The performance was evaluated by (1) accuracy, (2) outside target area removal, and (3) tooth cutting time, automatically using the generated feedback.

Results: Twenty-one participants completed all sessions. The results revealed a statistically significant effect of 3D vision over 2D vision on students' performance in terms of accuracy (p = 0.035). Stereoscopic 3D vision showed significant effect on outside target area removal in the first task (p = 0.035). Tooth cutting time was the same under both conditions (p = 0.766). The findings revealed improvement in accuracy score and reduction in outside target area removal over the course of the experiment under both conditions. Comparing the difference in 3D effect in the early and advanced learning groups revealed no significant difference among the groups (p > 0.05).

Conclusion: Utilizing stereoscopic 3D vision in the training session improved students' perception of depth which led to more accurate tooth cutting within the target area, and less outside target area removal. However, 3D shows a limited impact on task completion time.

Purpose: This study explored themes previously identified as central to holistic professional school success, as related to traditional academic achievement, resilience, and grit measures.

Methods: This cross-sectional study surveyed third- and fourth-year US dental students. Items addressed themes previously identified as central to professional school success, including need for cognition, patient ownership, collective orientation, grit, and resilience. Traditional academic metrics were also included. Statistical analyses comprised one-way analysis of variance (ANOVA), simple linear regression, and stepwise multiple regression procedures.

Results: A total of 126 students participated (81% response rate). Collective orientation, need for cognition, patient ownership, and resilience did not significantly correlate with grade point average (GPA), whereas grit did, r = 0.29. Need for cognition and patient ownership combined significantly predicted grit with approximately 35% of variance explained. Approximately 25% of variance in resilience scores was accounted for by need for cognition, coupled with collective orientation. Grit and resilience significantly correlated, r = 0.59.

Conclusions: Grit significantly predicted both traditional and alternative metrics of success among dental students, particularly need for cognition and patient ownership. A high need for cognition is consistent among students who display both grit and resilience. Neither resilience nor the alternative measures of success predicted traditional academic metrics.
