Garre's osteomyelitis radiographic appearance shows

  1. Periosteal reaction

  2. Loss of lamina dura

  3. Thickening of cortex

  4. Widening of periodontal ligament space

The correct answer is: Thickening of cortex

Garre's osteomyelitis is a serious bacterial infection that affects the bones in the jaw and causes a thickening of the bone cortex. This is visible on radiographs as a radiopaque (light-colored) band surrounding the affected bone. Options A, B, and D are all incorrect because they do not specifically describe the thickening of the cortex, which is the main characteristic of Garre's osteomyelitis. Periosteal reaction is the formation of new bone tissue in response to injury or infection, but it does not specifically indicate Garre's osteomyelitis. Loss of lamina dura is a radiographic finding that can be seen in periodontal disease, but it is not specific to Garre's osteomyelitis. Widening of the periodontal ligament space can be a sign of many different dental conditions and does not directly relate to
