Participation in an existing massive open online course in dentistry during the COVID-19 pandemic.

The coronavirus disease 2019 (COVID-19) pandemic presented unprecedented challenges and interruptions to education at all levels. As many across the world were required to stay at home, virtual educational resources were developed and relied upon to provide all levels and subjects of instruction. Introduction to Dental Medicine, a massive open online course in dentistry, experienced an increase in enrollment during the start of the pandemic and learners displayed a positive reception to the information provided. Introduction to Dental Medicine was particularly well positioned as a resource during the pandemic given its availability, established nature, and the wide accessibility of course material. As disruptions to normal activities continue, this and other virtual educational methods may continue to play a central role in education and exposure to dentistry.
