The outbreak of COVID-19 necessitated abrupt transition from on campus, face-to- face sessions to online, distance learning in higher education institutions. The purpose of this study was to investigate the perceptions of postgraduate dental learners and instructors about the transition to distance learning, including the changes to the learning and teaching and its efficaciousness. A mixed-methods approach to research was utilized. All the instructors and postgraduate learners were invited to participate in the online survey. Quantitative data was analyzed using descriptive and inferential analyses on SPSS for Windows version 25.0, and for the responses to the open-ended questions, multi-staged Thematic Analysis was utilized. Both groups of stakeholders: learners and instructors, were quite satisfied with the rapid transition to distance learning due to COVID-19. Instructors were significantly more satisfied than the learners. The stakeholders adapted well to the change. The perception of the stakeholders regarding the case-based scenarios significantly influenced their level of satisfaction. As perceived by the stakeholders, the transition to distance learning entailed advantages and challenges. Going through the experience equipped the stakeholders with lessons learned and enabled them to develop informed opinions of how best to sustain learning and teaching irrespective of how matters unfold in relation to the pandemic. In conclusion, the worldwide dental education community faced unprecedented challenges due to the onset of COVID-19. Yet, in the grand scheme of things, it is important for decision-makers not to miss-out on the worthwhile opportunities, inherent in the experience, to reinforce curriculums, and maximize the learning and teaching.

To evaluate the utility of an individualized template for corrective surgeries for patients suffering from mandibular asymmetry.

Direct oral anticoagulants (DOACs) are increasingly used as alternatives to warfarin because of the superior pharmacokinetic properties. Clinical guidelines on the influences of DOACs for dental procedures have emerged, but all of necessity based on low‐quality available evidence. Herein, we share our experience with a case series, and propose a protocol regarding the management of dental patients taking DOACs.

The aim of this study was to assess the influence of patients' and surgical variables on the onset and duration of action of local anesthesia (LA) in mandibular third‐molar (M3) surgery. Patients scheduled for mandibular M3 surgery were considered for inclusion in this prospective cohort study. Patients’ and surgical variables were recorded. Two per cent (2%) lidocaine with 1:100,000 epinephrine was used to block the nerves for extraction of mandibular M3. Then, the onset of action and duration of LA were monitored. Univariate analysis and multivariate regression analysis were used to analyze the data. The final cohort included 88 subjects (32 men and 56 women; mean age ± SD = 29.3 ± 12.3 yr). With univariate analysis, age, gender, body mass index (BMI), smoking quantity and duration, operation time, and ‘volume of local anesthetic needed’ significantly influenced the onset of action and duration of LA. Multivariate regression revealed that age and smoking quantity were the only statistically significant predictors of the onset of action of LA, whereas age, smoking quantity, and ‘volume of local anesthetic needed’ were the only statistically significant predictors of duration of LA. Further studies are recommended to uncover other predictors of the onset of action and duration of LA.
