[{'content': 'The following radiographic finding is associated with: \nSelect and explain. \nA. Fibrous dysplasia, B. Paget’s disease, C. Hyperparathyroidism, D. Osteoma', 'role': 'user'}, {'content': 'Answer: B \nExplanation: The\xa0bone\xa0progresses through\xa0an\xa0osteolytic\xa0and\xa0osteoblastic\xa0phase,\xa0which\xa0usually occur simultaneously, but with the osteoblastic phase being ultimately more dominant. Thus, the radiographic appearance is that of an increased radiopacity of the jaws. The\xa0bone\xa0tends\xa0to\xa0become\xa0more\xa0granular\xa0in\xa0appearance\xa0and\xa0the\xa0lamina\xa0dura\xa0is obscured or difficult to identify. Here the bony trabeculae, particularly in\xa0the\xa0posterior\xa0part\xa0of\xa0the\xa0body\xa0of\xa0the\xa0mandible,\xa0may\xa0show\xa0linear\xa0striations.\xa0In addition, the teeth may show hypercementosis. A more classical appearance is that\xa0of\xa0granular looking bone\xa0containing\xa0scattered\xa0islands\xa0of\xa0dense\xa0or\xa0fluffy-looking bone, particularly in the region of the tooth apices.\nKey Concepts', 'role': 'assistant'}]
