Osteomyelitis of the mandible may follow which events?

Osteomyelitis, or a bone infection of the mandible, can develop as a result of many different factors. This includes radiotherapy, dentoalveolar abscess, and fractures. These events all have the potential to damage the bone and create an entry point for bacteria to enter and cause an infection. Therefore, it is important to treat these conditions promptly to prevent the development of osteomyelitis. The other options (A, B, and C) can be ruled out as the incorrect answers because they only list one possible cause, whereas the correct answer (D) includes all of these events.
