National Dental Examining Board of Canada (NDEB) Practice Exam

When a patient falls on their chin and fractures the right subcondylar region, the most likely symptoms would be pain and tenderness. This is because the subcondylar region is the bony projection just below the joint of the jaw and connects to the skull. Therefore, it is a sensitive area and experiencing pain and tenderness is a common response to a fracture in this region. None of the other options, such as trismus (difficulty opening the mouth), swelling, numbness, discoloration, bleeding, or infection, are directly related to a fracture in the subcondylar region and are therefore incorrect.
