          Abstract

          Statement of problem

          Synchronous online prosthodontic courses became a popular learning mode during the 2020 COVID-19 pandemic crisis. Nonetheless, the extent of learner participation and completion of these courses remains unknown.

          Purpose

          The purpose of this study was to assess learner behaviors in synchronous online prosthodontic continuing education lectures in China during the 2020 COVID-19 pandemic.

          Material and methods

          All live online prosthodontic courses held by an online dental school in China from February to May 2020 were retrieved. The no-cost lectures could be accessed anonymously and viewed repeatedly on the day of broadcast. Learning behavior data (teacher speaking time, audience total, timing of first visit to the online classroom, viewing time, and completion rate) were obtained. Learning progress was calculated by dividing viewing time by teacher speaking time. When a learner progressed through 95% of a lecture, the lecture was considered completed.

          Results

          A total of 41 781 learners participated in 18 online prosthodontic courses, which had a mean duration of 77.2 ±15.8 minutes. For each lecture, 2321 ±1454 participants attended, with 510 ±404 participants completing each session. There were 13 098 participants (31.35%) who viewed the lectures for less than 1 minute. Approximately half of the participants viewed the lectures for less than 10 minutes, with their learning progress failing to pass 10%. The average completion rate was 21.97%, with variation in completion rate dependent on when a learner first visited the online classroom. Significant differences were found among the lecture completion rates and the timing of the first visit to the online classroom ( P<.001).

          Conclusions

          Synchronous online prosthodontic education courses in China had a high number of participants but low learning progress and completion rates during the 2020 COVID-19 pandemic.

            Coronavirus Disease 2019 (COVID-19): Emerging and Future Challenges for Dental and Oral Medicine

            The epidemic of coronavirus disease 2019 (COVID-19), originating in Wuhan, China, has become a major public health challenge for not only China but also countries around the world. The World Health Organization announced that the outbreaks of the novel coronavirus have constituted a public health emergency of international concern. As of February 26, 2020, COVID-19 has been recognized in 34 countries, with a total of 80,239 laboratory-confirmed cases and 2,700 deaths. Infection control measures are necessary to prevent the virus from further spreading and to help control the epidemic situation. Due to the characteristics of dental settings, the risk of cross infection can be high between patients and dental practitioners. For dental practices and hospitals in areas that are (potentially) affected with COVID-19, strict and effective infection control protocols are urgently needed. This article, based on our experience and relevant guidelines and research, introduces essential knowledge about COVID-19 and nosocomial infection in dental settings and provides recommended management protocols for dental practitioners and students in (potentially) affected areas.

              The impact of the COVID-19 epidemic on the utilization of emergency dental services

              Background/Purpose To assess how the current COVID-19 epidemic influenced peoples' utilization of emergency dental services in Beijing, China. Methods The first-visit patients seeking emergency dental services before or at the beginning of the COVID-19 epidemic were retrieved. Their demographic characteristics and the reasons for visiting were recorded and analyzed. Results There were 2,537 patients involved in this study. Thirty-eight percent fewer patients visited the dental urgency at the beginning of the COVID-19 epidemic than before. The distribution of dental problems has changed significantly. The proportion of dental and oral infection raised from 51.0% of pre-COVID-19 to 71.9% during COVID-19, and dental trauma decreased from 14.2% to 10.5%. Meanwhile, the non-urgency cases reduced to three-tenths of pre-COVID-19. Conclusion Within the limitation of this study, the COVID-19 epidemic had a strong influence on the utilization of emergency dental services.
