What radiographic features on a jaw radiograph suggest osteomyelitis in advanced disease?

• A. No radiographic changes
• B. Areas of radiolucent bone with possible sequestra and surrounding sclerosis
• C. Normal lamina dura continuity
• D. Uniform radiopacity of the jawbone

Answer: (B)

Advanced jaw osteomyelitis shows a destructive pattern with bone loss that appears radiolucent, often containing sequestra—dead bone fragments that stand out within the lucent areas. Surrounding this destruction, the bone may respond with sclerosis as part of a reparative process, and there can be involucrum formed around the necrotic zones. This combination of radiolucent areas with sequestra and surrounding sclerosis is the hallmark of advanced disease on a jaw radiograph. The alternatives don’t fit because no changes would contradict active infection, a normal lamina dura continuity would not reflect the destructive process, and uniform radiopacity does not capture the focal bone destruction with dead fragments characteristic of osteomyelitis.
