evidence: Several learning modalities have been implemented to improve learning about Traumatic Dental Injuries (TDIs) worldwide. Free online courses about TDIs might be an effective and convenient approach for equipping Syrian dentists with essential competencies during the Syrian crisis. Therefore, this qualitative study with a descriptive phenomenological method was undertaken to explore the lived experience of Syrian dentists enrolled in an online course about TDIs and investigate areas requiring improvement. [...] Syrian dentists can benefit from online courses if constraints and various learning needs are addressed during the design and delivery of online courses. Future work is still required to identify other effective instructional modalities that equip Syrian dentists to overcome challenges and enhance their learning.
