OMS case studies
OMS · Put your knowledge to work in context.
The OMS exam is a multiple-choice assessment built around oral and maxillofacial surgery and the disciplines that surround it in everyday practice. Candidates are typically dentists preparing for a scope-of-practice or specialty-adjacent credential, or clinicians who want an independent check of their knowledge across surgical, medical, and restorative topics. The OMS case studies are 5 cases and about 5,015 words.
